Abstract
The pandemic of coronavirus disease 2019 (COVID-19) secondary to the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has bestowed an unprecedented challenge upon us, resulting in an international public health emergency. COVID-19 has already resulted in > 1,600,000 deaths worldwide and the fear of a global economic collapse. SARS-CoV-2 is notorious for causing acute respiratory distress syndrome, however emerging literature suggests various dreaded cardiac manifestations associated with high mortality. The mechanism of myocardial damage in COVID-19 is unclear but thought to be multifactorial and mainly driven by the host’s immune response (cytokine storm), hypoxemia and direct myocardial injury by the virus. Cardiac manifestations from COVID-19 include but are not limited to, acute myocardial injury, cardiac arrhythmias, congestive heart failure and acute coronary syndrome. Cardiac imaging is paramount to appropriately diagnose and manage the cardiac manifestations of COVID-19. Herein, we present cardiac imaging findings of COVID-19 patients with biomarker and imaging confirmed myocarditis to provide insight regarding the variable manifestations of COVID-19 myocarditis via Cardiac MRI (CMR) coupled with CMR-edema education along with recommendations on how to incorporate advanced CMR into the clinicians’ COVID-19 armamentarium.

Background
Coronaviruses are single stranded positive sense RNA viruses with ability for rapid mutation. There are at least six human susceptible coronaviruses that have been identified, among which Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) and Middle East Respiratory Syndrome coronavirus (MERS-CoV) are known to cause severe acute respiratory distress syndrome. SARS-CoV-2 is a novel coronavirus with similar pathogenicity as SARS-CoV and uses the angiotensin converting enzyme 2 (ACE2) receptors to enter human cells [1]. The outbreak of this novel coronavirus first occurred in December 2019 in Wuhan, China and has spread across the world rapidly. The World Health Organization declared it to be a pandemic in March 2020 [2]. The number of cases has increased over the past eight months and as of now, it has reached > 73 million infected and > 1,600,000 deaths across the globe. Although the most common presentation is acute respiratory failure, cardiovascular complications are increasingly reported and are a dreaded manifestation due to increased mortality. While most of the research has so far focused on investigating the causality, pathophysiology, treatment and outcomes of myocarditis in COVID-19 patients, there is paucity of literature on identifying patterns on cardiac imaging in this population. We present cases of COVID-19 myocarditis that have been published with cardiac imaging findings dovetailed with unique aspects of CMR-derived myocardial-edema imaging.
Mechanism of COVID-19-related cardiovascular disease
Coronaviruses, such as MERS-CoV are known to cause myocarditis [3]. Due to similarities in pathogenicity of MERS-CoV and SARS-CoV-2, cardiac involvement with SARS-CoV-2 was suspected and first described in Wuhan, China when 5 out of 41 COVID-19 patients were found to have acute myocardial injury [4]. Myocarditis is considered to be an important cause of acute myocardial injury in these patients and has been identified on cardiac autopsies from the National Health Commission PRC, demonstrating myocyte necrosis along with mononuclear leukocyte infiltration in COVID-19 deceased patients [5,6,7]. Moreover, a study in China on recovered COVID-19 patients who had reported cardiac symptoms revealed that 58% of them had evidence of myocarditis on cardiac MRI (CMR), implying that the incidence of myocardial involvement with SARS-CoV-2 is much more common than previously thought in this population [8]. The mechanism for acute myocardial injury and myocarditis is yet to be fully elucidated but is suspected to be secondary to a severe inflammatory response and cytokine storm, resulting in direct myocardial damage (Fig. 1a) [9, 10]. Similarly, this fulminant cytokine release may cause acute coronary syndrome, due to increased oxidative stress, coronary plaque destabilization and rupture [11]. Alternative theories include acute respiratory failure causing oxygen supply-demand mismatch to the myocardium and direct viral entry into cardiac myocytes through the ACE2 receptors [12].
Diagnosing COVID-19 myocarditis: use of cardiac imaging
Myocarditis is defined as inflammation of the cardiac muscle by infectious or noninfectious etiologies [13]. Clinical modalities that are traditionally used to evaluate cardiac injury include cardiac biomarkers (cardiac troponin, creatine kinase MB, C-reactive protein (CRP), N-terminal pro B-type natriuretic peptide (pro-BNP)), non-invasive imaging (electrocardiogram, echocardiogram, nuclear perfusion studies, cardiac CT and CMR), and invasive techniques (coronary angiography, endomyocardial biopsy). Due to the extremely high infectivity rate of this novel coronavirus, careful clinical judgement has been advised by multiple cardiovascular societies on the appropriate use criteria for performing cardiac imaging which is essential in the diagnosis of COVID-19 myocarditis [14,15,16,17,18].
Transthoracic echocardiogram (TTE) is the initial non-invasive imaging modality of choice since it can provide valuable data for diagnosing myocardial infarction, aortic root dissection, pericardial disease or valvular heart disease. Common TTE findings in myocarditis include new left ventricular (LV) wall motion abnormalities, diastolic dysfunction, myocardial edema, intraventricular thrombus, and pericardial effusion [19]. Interestingly, recently published study on echocardiographic findings in COVID-19 patients demonstrated that only a third of the hospitalized patients have normal biventricular function. Although LV systolic function was preserved in majority of patients, LV diastolic and RV function were frequently impaired [20]. On the other hand, a negative echocardiogram is inadequate to definitely rule out myocarditis and in such cases, CMR can be highly valuable.
Since the original first dozen case reports there have been many more, we determined to discover pattern of CMR findings in patients with COVID-19 myocarditis [21,22,23,24, 6, 25,26,27,28,29,30,31,32,33,34,35,36]. It is noteworthy that COVID-19 has shown sexual dimorphism with men having higher susceptibility for infection and complications [37,38,39]. Of the published myocarditis cases that we reviewed [21,22,23,24, 6, 25,26,27,28,29,30,31], 8 (67%) were male, though data regarding mortality was limited. TTE was performed in 11 out of 12 patients and interestingly 5 (45%) were reported to have normal LV systolic function. The most common findings in those with abnormal systolic function included global hypokinesis and moderate to severe LV systolic dysfunction. Acute diastolic dysfunction was reported in one patient and pericardial effusion was present in 3 cases, including one patient with cardiac tamponade requiring emergent pericardiocentesis. Interestingly, nuclear imaging was not performed in any of our discussed case reports.
CMR was performed in 7 out of 12 patients. Short tau inversion recovery and T2-mapping sequences in most of these patients showed significant interstitial myocardial edema. Phase sensitive inversion recovery sequences showed late gadolinium enhancement (LGE) in all but two cases [6, 31, 28]. Interestingly, among the five patients who had normal cardiac function on TTE, three patients (60%) had confirmed acute myocarditis by CMR [22, 27, 31]. Thus, in COVID-19 patients who lack typical diagnostic features in their echocardiogram, the diagnosis of myocarditis can be made by CMR, aligning with prior data suggestive of CMR having more diagnostic accuracy in detecting myocarditis [40].
In one patient, echocardiography with dynamic-3D volume reconstruction was utilized and showed normal apical contraction along with hypokinesia of the mid and basal segments of LV suggesting reverse TakoTsubo pattern. CMR showed diffuse myocardial edema and lack of LGE to suggest myocardial scarring. Subsequent endomyocardial biopsy also exhibited diffuse T-cell lymphocytic infiltrates and interstitial edema with limited foci of necrosis. No replacement fibrosis was detected, suggestive of an acute inflammatory process. SARS-CoV-2 genome was not detected in myocardium during molecular analysis, suggesting an acute virus negative lymphocytic myocarditis associated with SARS-CoV-2 respiratory infection [28].
The diagnosis of myocarditis is often difficult, because myocardial inflammation maybe global, regional or patchy. The presumptive “gold standard” for the diagnosis of myocarditis is myocardial biopsy with pathologic evidence of inflammation. However, even biopsy is not reliable if there is no global myocardial cellular involvement. Unlike echocardiography, nuclear imaging and angiography, CMR is capable of “tissue characterization”, distinguishing scarring, hemorrhage, infarction, infiltrate and tumor from interstitial myocardial edema [41].
Attributes of CMR
CMR does not require radiation exposure, but rather uses magnetic properties and radio waves to generate motion images with excellent wide-field spatial resolution. When placed into a magnetic field, the hydrogen protons of myocardial water molecules effectively can be thought to align into a “due North” orientation (Video 1). A “coil” transmitter sends a radio wave of specific physical characteristics (called a “pulse sequence”) into the myocardium deflecting the hydrogen protons into a “flipped angle” position. When the pulse sequence is terminated, the hydrogen protons immediately go back to “due North” (Video 2), giving off a reflected radio wave which is mathematically converted via a Fourier transform to clinically useful image (Fig. 1b, c). The coil alternates rapidly between transmitter and receiver, to accomplish image acquisition. When coupled with electrocardiographic gating, high quality motion images are generated. By varying the physical properties of the transmitted radio wave pulse sequence, the appearance of cardiac tissues varies, allowing MRI to achieve “tissue characterization” [41, 42].
The workhorse imaging pulse sequence for CMR is steady state free precession (SSFP). SSFP imaging is very useful for assessing structural aspects of myocardial tissue and valve motion. Similar to echocardiography, multiple imaging “slices” are obtained to allow visualization of as many of the cardiac structures as possible. However, CMR has a full field of view and is not limited to a 90° arc of imaging within the confines of a thoracic intercostal space. This advantage of CMR is critically important in being able to fully assess the right ventricle (RV).
Detection of myocardial edema (an indirect marker of inflammation) by CMR uses assessment of hydrogen proton movement as it is forced into and out of the “flip angle” position. The time it takes the hydrogen proton to return from the “flip angle” position to “due North” position in the X–Y axis plane is called the “T1 relaxation time” (Fig. 1d). The time it takes the hydrogen proton to return from the “flip angle” position to “due North” in the Y-Z axis plane is called the “T2 relaxation time”. Because T1 and T2 relaxation times vary with water content, quantification of these relaxation parameters on a pixel-by-pixel basis, with color encoding, yield valuable clinical information about myocardial edema and possible inflammation (Fig. 1e). Increased myocardial water content (i.e. edema) prolongs both T1 and T2 relaxation times. Use of this imaging technique not only allows detection of myocardial edema in myocarditis, but also provides information as to whether the inflammation is global, regional or patchy. If necessary, this information provides valuable guidance for determining an appropriate site for endomyocardial biopsy.
Descriptive cases of COVID-19 myocarditis
In our recent experience, we encountered four emblematic cases revealing the myriad of COVID-19 myocarditis presentations. The first was a 65-year old Caucasian male with multiple cardiovascular comorbidities including paroxysmal atrial fibrillation on systemic anticoagulation but preserved LV systolic function, who presented with flu-like symptoms and rapidly progressed to acute hypoxemic respiratory failure due to PCR confirmed COVID-19 disease, requiring ventilator support. He was initially treated with hydroxychloroquine, azithromycin and plasmapheresis with clinical improvement and was successfully extubated. Daily troponin T levels were checked and were normal until day 10 of admission, when they were found to be elevated and up-trending (peak 0.61 ng/mL), but interestingly, the patient was hemodynamically stable and remained asymptomatic. Electrocardiogram revealed non-specific T wave abnormalities in the anterolateral leads and TTE revealed new LV regional wall motion abnormalities consistent with a reverse TakoTsubo pattern with LV ejection fraction (EF) of 40–45% (Fig. 2). The patient suffered from a pulseless electrical arrest 24 h later and despite successful return of spontaneous circulation following cardiopulmonary resuscitation, his course was complicated with multiorgan failure and eventually expired. Following his resuscitation, pulmonary embolism was ruled out and his decompensation, given the presentation, was attributed to COVID-19 myocarditis. These authors (we) recently published this interesting case [36].
Another interesting case was a 67-year old Caucasian female with history of hypertension, who presented with symptoms of congestive heart failure (CHF). She was found to have LV systolic dysfunction with mild global hypokinesis on echocardiogram along with elevated troponin I levels (0.31 ng/mL). CMR revealed LV systolic dysfunction (EF 30%) and moderate global RV hypokinesis that was not well visualized by TTE. T1 and T2 relaxation mapping were suggestive of myocardial wall edema and LGE was noted on phase sensitive inversion recovery especially involving the RV which was not appreciated on the TTE. Although she was never considered high-risk for SARS-CoV-2 infection per the CDC guidelines, her PCR was positive for SARS-CoV-2, unveiling final diagnosis of acute COVID-19 myocarditis (Fig. 3). With regard to therapy, hydroxychloroquine was not a viable option due to prolongation of the QTc interval. Alternatively, colchicine was initiated due to the substantial biventricular edema and on day nine she was eventually discharged. Colchicine was favored in our patient for an important reason. Hydroxychloroquine is believed to exert its anti-inflammatory effect by interfering with antigen processing, which is required to stimulate CD4+ T cells for an auto-immune response, typical of a cytokine storm [43]. Colchicine does not interfere with stimulation of CD4+ T cells but rather affects white blood cells, causing microtubule depolymerization, which severely limits WBC degranulation. In addition, colchicine directly disrupts the NOD-like receptor protein-3 (NLRP3) inflammasome protein complex, which is a critical component of an anti-inflammatory response [44,45,46]. Moreover, increased resolution of myocarditis, associated with pericarditis, among patients being treated with colchicine was noted by Morgenstern et al. [47].
We encountered a 78-year old Caucasian man patient with multiple cardiac comorbidities but preserved LV systolic function at baseline, who was admitted with flu-like symptoms and acute hypoxemic, ventilator-dependent respiratory failure. He was found to be positive for COVID-19 disease. An electrocardiogram revealed ST segment elevation in the anterior leads along with elevation of troponin T levels to 4.1 ng/mL, and his echocardiogram demonstrated new severe global LV dysfunction with EF of 35% (Fig. 4). Surprisingly, the epicardial coronary arteries were without significant disease on invasive coronary angiogram. This patient eventually expired due to multi-organ failure.
Lastly, a 72-year old Caucasian man with history of hypertension, hyperlipidemia and type 2 diabetes, who was admitted with CHF, was noted to have asymptomatic rising troponin I (peak 0.14 ng/mL), along with anterior T wave inversions on electrocardiogram. Coronary arteriography demonstrated significant stenosis of the proximal LAD and second obtuse marginal branch of the left circumflex artery (LCX), with hypokinetic anterior LV wall, all raising concern about the viability of myocardium in the distribution of LAD. The edema of the LV wall induced by inflammation from COVID-19 myocarditis would increase LV wall tension and thus increase myocardial oxygen demand, potentially exacerbating the ischemia of the underlying coronary atherosclerosis. CMR demonstrated a completely viable myocardium but diffuse myocardial edema on T1 and T2 mapping technique, with global LV hypokinesis (EF 38%), supportive of myocarditis (Fig. 5). This patient was found to have positive PCR for COVID-19. Here, the CMR was instrumental in redirecting care to COVID-19 myocarditis, not to unnecessary coronary artery bypass grafting (CABG) with the further risk of infecting several health-care workers.
Overall, in our experience, CMR showed more diffuse involvement of myocardium in COVID-19 induced myocarditis compared to non-COVID myocarditis. All of our T1 and T2 relaxation time values were quantified from Siemens MyoMap software. Normal T1 and T1 values were obtained from series of normal patients to establish lab normal range (Normal T1 values were 910–930 msec and normal T2 values were 40–43 msec for our lab). More than 2 standard deviation (SD) above our normal range was considered elevated.
Myocarditis versus acute coronary syndrome
Due to concerning clinical presentation in certain patients, SARS-CoV-2 being a potential culprit for coronary plaque rupture and probability to cause myocardial ischemia with pleomorphic mechanisms, clinical judgment is a requisite in decision making as some patients may require invasive angiography to exclude acute coronary syndrome. In a New York City study of COVID-19 patients, 18 patients had ST-segment elevations on electrocardiogram, however, only 8 patients (44%) had clinical myocardial infarction and only 6 (33%) had evidence of obstructive coronary artery disease, whereas the remaining had non-coronary artery related myocardial injury; 13 (72%) of these patients died during their hospitalization [48]. From our reviewed cases with COVID-19 myocarditis, 5 (42%) had ST-segment elevation on initial electrocardiogram, of which 4 underwent coronary angiography and the diagnosis of acute coronary syndrome was excluded in all of them. This has considerable ramifications as the discerning clinician must balance classic teachings with contemporary data both with far-reaching implications for balancing patient care with healthcare protections. In part, this was the impetus for our review and ultimate recommendations.
Outcomes of patients with COVID-19-related acute myocarditis
It is consistently reported that patients with several cardiac comorbidities have much higher likelihood of having myocardial involvement. These patients are usually critically ill on presentation and suffer a high mortality rate [49]. A cohort study from Wuhan, China studying 416 hospitalized COVID-19 patients discovered that 82 patients (20%) had acute myocardial injury and those patients had a very high mortality rate (42 patients, 51%). When compared to patients without myocardial injury, patients with myocardial injury were significantly more likely to have cardiac comorbidities such as coronary artery disease (29% vs. 6%) and heart failure (15% vs. 2%) [50]. Another observational study of 187 COVID-19 hospitalized patients reported that 28% had evidence of myocardial injury. Overall mortality was 23% and was significantly higher among patients who had elevated troponin levels, especially in those with underlying cardiovascular comorbidities [49]. Additionally, a meta-analysis revealed that critically ill COVID-19 patients tend to have abnormal cardiac troponin levels and longitudinal monitoring of troponin levels might be able to predict those at risk for adverse clinical outcomes during the hospital admission [51]. Similarly, as described above, in one of our COVID-19 patients with myocarditis we noticed a new, otherwise unexplained troponin elevation on routine daily blood work on day 10 of hospitalization. An echocardiogram on the same day revealed new LV wall motion abnormalities with reverse TakoTsubo pattern. This was followed by a rapid clinical deterioration and cardiac arrest within 24 h.
It is also noteworthy that due to concerns for transmission of the virus to healthcare workers and other patients, the true incidence of acute imaging-confirmed myocarditis in COVID-19 patients is likely grossly underdiagnosed and underreported. However, based on ample evidence so far, myocarditis appears to be an adverse prognostic sign and is associated with rapid clinical deterioration in these patients. As more literature on COVID-19 myocarditis becomes available, we will be able to identify predictors of myocardial injury and hopefully, effective treatment options for these critically ill patients.
Proposed CMR algorithm for COVID-19 patients
Integrating the published and unpublished data along with our aggregate CMR experience [52], we propose the following algorithm to incorporate CMR in the suspected COVID-19 patients with low to high pre-test probability myocarditis:
-
(1)
If non-ST- elevation myocardial infarction (NSTEMI) via electrocardiogram and invasive /CT coronary angiogram is negative or mildly abnormal, in the setting of normal or abnormal TTE, consider CMR for myocarditis-edema imaging (See Fig. 6a).
-
(2)
If ST-elevation myocardial infarction (STEMI) via electrocardiogram and invasive/CT coronary angiogram is negative or mildly abnormal, in the setting of normal or abnormal TTE, consider CMR for myocarditis-edema imaging (See Fig. 6b).
Economic basis for upfront consideration for CMR
The cost to the US healthcare system for inpatients with suspected or proven COVID-19 is fixed by DRG. However, for outpatients with suspected or proven COVID-19, the cost to the healthcare system of diagnostic imaging is a function of APC determined by Medicare. 2019 Medicare APC reimbursement amounts are provided in Table 1. Using the diagnostic flow chart suggested in Fig. 6, the total cost to the healthcare system to establish a diagnosis of myocarditis via the CMR strategy is $691.75. Using the 2-D echo with stress diagnostic approach for an intermediate pre-test probability CAD patient, the cost to the healthcare system to establish a myocarditis diagnosis is $1686.73. While cardiac MRI is capable of assessing structure, function, perfusion, inflammation and viability in one study, 2-D (with or without stress) echocardiographic-defined myocarditis is effectively a diagnosis of exclusion as it is not capable of assessing inflammation. Accordingly, the cardiac MRI imaging strategy additionally reduces cost to the healthcare system by 59% or $994.98 per patient.
Future directions
To date, published trials have used the hard endpoints for morbidity and mortality. As intimated above, an imaging-based outcome might offer an improved understanding rooted on a pathophysiologic understanding of CMR-based edema imaging. Consequently, based on the known anti-inflammatory effects of colchicine, a large (6000 patients) randomized, double-blind clinical trial in Montreal was initiated comparing colchicine vs. placebo in COVID 19 patients [53]. Extending this notion, based on the herein-described data and our experience, our CMR Research Group is initiating a randomized, double-blind two-arm clinical trial with planned enrollment of 400 COVID-19 patients within 72 h of diagnosis, with trial arms of dexamethasone vs. colchicine (DEXCOL). This study will also assess cardiac biomarkers of troponin, pro-BNP and high sensitivity-CRP in all enrolled patients to assess the true incidence of myocarditis, confirmed with CMR, in COVID-19 positive patients. An interesting aspect of this trial is that it is designed to be a longitudinal study such that entry criteria is based on an outpatient diagnosis, not as traditionally tracked from an inpatient randomization schema. The basis for this non-traditional approach is that it provides the opportunity for a more fundamental understanding of COVID-19 over a longer period of time and an improved understanding for how morbidity and mortality may be affected by a focused attack on the inflammatory cascade with respect to several CMR-based assessments.
Limitations
Our review is limited by the evolving stage of this highly contagious virus, resulting in limited myocarditis data availability. Moreover, cases of COVID-19 myocarditis with available cardiac imaging are highly underreported, likely due to limited testing in order to limit the spread of the virus. Other limitations include the significant heterogeneity of patient selection, study designs and outcomes, which are at high risk to introduce bias. Due to the current pandemic, a significant amount of literature is being published in preprinted form without peer review, adding further limitation. Despite this, the inflammation cascade of COVID-19 triggered myocarditis is an important source of morbidity and mortality and is a source of major clinical and academic focus.
Conclusions
Acute myocarditis is relatively common in critically ill COVID-19 patients. The presentation of these patients is variable including LV systolic and diastolic dysfunction, arrhythmias and acute coronary syndrome. The majority of those cases can be sufficiently diagnosed with TTE, however CMR can be exceptionally helpful in many cases, especially equivocal cases where there is evidence of myocardial injury by cardiac biomarkers but inconclusive by TTE. CMR findings include myocardial edema seen in all patients with evidence of myocarditis, and notably, LGE is reported in the majority patients, consistent with myocardial fibrosis and suggests an independent mortality signal. Yet, we advise, these techniques should be performed with caution, according to the cardiovascular society guidelines, due to the risk of spreading the virus to healthcare workers and other patients as in all cardiac imaging procedures. Nonetheless, especially as the risk of myocarditis is higher in older patients and those with multiple cardiac comorbidities all associated with a very poor prognosis, we propose that advanced imaging, especially CMR can play a pivotal role in risk-prognostication for the COVID-19 patients.
