ResumoIn this survey study of institutions across the US, marked variability in evaluation, treatment, and follow-up of adolescents 12 through 18 years of age with mRNA coronavirus disease 2019 (COVID-19) vaccine-associated myopericarditis was noted. Only one adolescent with life-threatening complications was reported, with no deaths at any of the participating institutions. In this survey study of institutions across the US, marked variability in evaluation, treatment, and follow-up of adolescents 12 through 18 years of age with mRNA coronavirus disease 2019 (COVID-19) vaccine-associated myopericarditis was noted. Only one adolescent with life-threatening complications was reported, with no deaths at any of the participating institutions. Since April 2021, more than 1000 patients have been reported to the Vaccine Adverse Event Reporting System (VAERS) with presumed myopericarditis following administration of the mRNA coronavirus disease 2019 (COVID-19) (Pfizer-BioNTech, Moderna) vaccine.1Centers for Disease Control and Prevention (CDC)Myocarditis and Pericarditis After mRNA COVID-19 Vaccination.https://www.cdc.gov/coronavirus/2019-ncov/vaccines/safety/myocarditis.htmlGoogle Scholar The afflicted patients predominantly have been male and <16 years of age, a vast majority of whom developed clinical features of myopericarditis within a few days after receiving the second mRNA COVID-19 vaccine (Pfizer-BioNTech, BNT162b2) dose.1Centers for Disease Control and Prevention (CDC)Myocarditis and Pericarditis After mRNA COVID-19 Vaccination.https://www.cdc.gov/coronavirus/2019-ncov/vaccines/safety/myocarditis.htmlGoogle Scholar The overall reported incidence of myopericarditis after administration of mRNA COVID-19 vaccine has been estimated to be 4.2 and 32.4 per million doses administered in female and male adolescents 12 through 17 years of age, respectively.2Centers for Disease Control and Prevention (CDC)Advisory Committee on Immunization Practices (ACIP).

A secondary objective of this study was to determine the rate of serious, life-threatening complications (cardiopulmonary arrest requiring resuscitation, need for mechanical circulatory support [extracorporeal membrane oxygenation, Impella or ventricular assist device use], and death) in these adolescents. After we obtained appropriate institutional review board approval, a questionnaire that inquired about the institutional practices regarding diagnosis, treatment, and follow-up of adolescents with VAM was emailed to pediatric cardiologists or pediatric infectious disease specialists at 107 institutions (the top 100 institutions in the US News ranking of pediatric cardiology programs and a few additional programs with which the authors were familiar) across the US between July 9, 2021, and August 9, 2021.11US News and World ReportBest Children's Hospitals for Cardiology & Heart Surgery.https://health.usnews.com/best-hospitals/pediatric-rankings/cardiology-and-heart-surgeryDate accessed: July 5, 2021Google Scholar The survey was forwarded to content experts for face validity.12Harahsheh A.S.

Nonparametric statistical tests were used to evaluate differences in medians, and P values <.05 were considered significant. The details of the institutional review board process, the questionnaire, data analysis, and statistics are provided in Appendices 1 and 2 (available at www.jpeds.com). Fifty-seven institutions (53%) returned a completed survey. As per the US Census Bureau classification, approximately two-thirds of the participating institutions were located in either the Midwest or the South, and a majority had a bed capacity of >200 beds (Appendix 1, Figure 1, A and B ).13US Census Bureau2010 Census Regions and Divisions of the United States.https://www.census.gov/geographies/reference-maps/2010/geo/2010-census-regions-and-divisions-of-the-united-states.htmlDate accessed: August 20, 2021Google Scholar Protocols and guidelines for treatment of adolescents with VAM were developed at 15 (n = 26%) of the participating institutions. Eleven institutions gave permission to publish their protocol. One institution used their multisystem inflammatory syndrome in children protocol for evaluation and treatment of adolescents with VAM. The 9 different VAM protocols used by the remaining 10 institutions are included in Appendix 3 (available at www.jpeds.com [2 institutions located in different geographic regions shared a common protocol]). All 31 institutions that responded to this question reported chest pain (100%) as a symptom of concern following administration of mRNA COVID-19 vaccine. Other concerning symptoms included shortness of breath (n = 27, 87%), chest tightness (n = 18, 56%), palpitations (n = 26, 81%), and fever (n = 16, 50%). The median duration of symptoms that prompted evaluation for VAM was 1 day (range 0-4 days). A majority of institutions reported symptoms after the second dose of mRNA COVID-19 vaccine (Appendix 1). Most institutions used cardiac troponin or creatine kinase myocardial band (98%), use of pro-N-terminal-brain type natriuretic peptide also was common (79%) (Appendix 1). COVID-19 antibody testing was performed by a majority (98%) of the institutions on these adolescents; however, a positive antibody test was included in diagnostic criteria for VAM by only a few (22%, 7/32) (Appendix 1). COVID-19 polymerase chain reaction (PCR) and respiratory viral panel were obtained by 45 (83%) of the institutions at the time of initial evaluation of these adolescents. Twenty-five (47%) of the institutions also obtained a comprehensive myocarditis viral panel during initial evaluation. Only 10 of 28 (36%) of the institutions included negative COVID-19 PCR in the diagnostic criteria for VAM. Most institutions (n = 50, 93%) measured serum C-reactive protein and erythrocyte sedimentation rate concentrations and obtained a complete blood count at admission. A comprehensive metabolic panel and serum D-dimer concentrations were obtained by 45 (83%) of the institutions during initial evaluation. Forty-two (79%) institutions obtained chest radiographs, 52 (95%) obtained echocardiograms, and 26 (47%) obtained a cardiac magnetic resonance imaging scan on adolescents with VAM at the time of initial evaluation. Electrocardiograms were obtained by all 55 (100%) institutions at the time of the initial evaluation. There was marked variability in institutional criteria for diagnosis of VAM. The diagnostic criteria used by the 26 institutions are shown in Appendix 4 (available at www.jpeds.com). A majority of the institutions used a combination of elevated inflammatory and cardiac biomarkers, electrocardiographic and echocardiographic or CMR abnormalities for diagnosis (Appendix 4). A positive antispike COVID-19 antibody titer was included in diagnostic criteria by only 4 (15%) institutions (Table I). The case definitions used by some of the institutions for diagnosis of VAM are shown in Appendix 5 (available at www.jpeds.com).Table ILaboratory, electrocardiographic, and imaging abnormalities considered suggestive of mRNA COVID-19 VAM (n = 26)VariablesNumber of institutions↑CRP/ESR12 (46%)↑BNP or pro-NT-BNP14 (54%)↑Troponin I or T26 (100%)Abnormal electrocardiogram23 (88%)Abnormal echocardiogram21 (81%)Abnormal cardiac MRI15 (58%)+ COVID-19 antispike antibody4 (15%)– COVID-19 antinucleocapsid antibody2 (8%)↑ D-dimer3 (11.5%)BNP, brain-type natriuretic peptide; CRP, C-reactive protein; ESR, erythrocyte sedimentation rate; MRI, magnetic resonance imaging; pro-NT-BNP, pro-N-terminal-brain type natriuretic peptide.

Common electrocardiographic abnormalities thought to be indicative of VAM included isolated diffuse ST-segment elevation (10%) or diffuse ST-segment elevation and T-wave inversion (58%), in addition to other nonspecific T-wave abnormalities (23%). Common echocardiographic and CMR findings that were considered potentially consistent with a diagnosis of VAM are shown in Table II (available at www.jpeds.com). Global ventricular dysfunction, pericardial effusion, and atrioventricular valve regurgitation were the 3 most common echocardiographic abnormalities. A combination of late gadolinium enhancement, myocardial edema, and pericardial effusion was considered suggestive of VAM by 75% of the institutions. Pediatric cardiologists were involved in management of these adolescents, most of whom were hospitalized (Appendix 1). There was wide variability in the first-line medications used to treat adolescents with VAM. A majority (35/54, 66%) of institutions initially treated these adolescents with nonsteroidal anti-inflammatory drugs (NSAIDs). The initial treatment consisted of intravenous immunoglobulin (IVIG) at a few institutions (n = 2, 4%). Other institutions treated with a combination of drugs (Appendix 1). One institution reported only conservative treatment without any specific medication. The criteria used to determine response to therapy were highly variable (Appendix 1). Although corticosteroids and IVIG were indicated as the most common second- and third-line therapeutic agents, there was marked variability (Appendix 1). The median upper limit of duration of hospitalization for the illness was 4 days (range 1-21 days) while the median of the lower limit of hospitalization for the illness was 1 day (range a few hours to 5 days) across 49 institutions. Only one institution cared for an adolescent with VAM who required ventilatory support. Eight institutions indicated using oxygen via nasal cannula and 4 indicated using high flow nasal cannula. Seventeen (34%) institutions reported patients with heart rhythm abnormalities. Six institutions reported at least 1 patient with premature ventricular contractions, 5 institutions reported at least one patient with nonsustained ventricular tachycardia, 2 institutions reported patients with atrioventricular block, and 3 institutions reported a patient with sustained ventricular tachycardia 1 of whom was treated with a beta-blocker. One institution reported a patient with electrocardiographic changes suggestive of ischemia. One institution reported a patient who had cardiac arrest and required cardiopulmonary resuscitation. This patient was supported with extracorporeal membrane oxygenation for 6 days and had normalized cardiac size and systolic function but persistent diastolic dysfunction and diffuse late gadolinium enhancement in the epicardium and mid-myocardium of the left ventricle on CMR by day 10 of hospitalization. No deaths were reported by any of the institutions, and no patient was reportedly supported by Impella or a ventricular assist device. Four institutions recommended return to full activity in <4 weeks, 5 institutions between 4 and 12 weeks, 14 institutions at 12 weeks, and 24 institutions between 12 and 24 weeks. Thirty-two (66%) of the institutions recommended a stress test before return to full activity (Appendix 1). The findings of our study, which included 57 institutions across the US, show that there is marked variability in diagnosis and management of VAM in adolescents. Although the Centers for Disease Control and Prevention has established a case definition for this condition, most of the institutions had formulated their own diagnostic criteria, which included (in addition to receipt of mRNA COVID-19 vaccine) clinical symptoms such as chest pain, shortness of breath or palpitations, laboratory abnormalities such as elevated inflammatory or cardiac biomarkers, electrocardiographic abnormalities, and noninvasive cardiovascular imaging abnormalities following administration of mRNA COVID-19 vaccine.14Centers for Disease Control and PreventionUse of mRNA COVID-19 Vaccine After Reports of Myocarditis Among Vaccine Recipients: Update from the Advisory Committee on Immunization Practices—United States, June 2021.https://www.cdc.gov/mmwr/volumes/70/wr/pdfs/mm7027e2-H.pdfDate accessed: August 28, 2021Google Scholar Most of the institutions reported 1 day as the threshold duration of symptoms after onset following administration of mRNA COVID-19 vaccine to consider evaluation for VAM; however, there was marked variability in responses (range 0-4 days). Similar variability was noted in the initial diagnostic evaluation. Cardiac biomarkers, inflammatory biomarkers, electrocardiograms, and echocardiograms were obtained by most of the institutions during initial diagnostic evaluation. However, there was more variability in using cardiac magnetic resonance imaging, evaluating for other causes of myocarditis, and measuring serum COVID-19–specific antispike and antinucleocapsid antibodies. The treatment of these patients was also widely variable. A pediatric cardiologist was central to management of these patients, with additional support from pediatric infectious disease and other specialists at some institutions. Although NSAIDs were the most commonly used first-line agents for treatment of these patients, steroids and IVIG were the most likely to be used second- and third-line agents, respectively. However, marked variability was noted in the first-line, second-line, and third-line therapeutic regimens, with a number of institutions using drug combinations. Most institutions admitted these adolescents for evaluation and management; however, a few managed these adolescents in the outpatient setting with reported good outcomes. Heart rhythm problems were common in these patients, with one-third of the institutions reporting patients with new-onset ectopy, heart block, or arrhythmia. The findings of this survey study are consistent with the results of previous studies, which have shown a high arrhythmia burden in adolescents hospitalized with acute myocarditis.15Miyake C.Y. Teele S.A. Chen L. Motonaga K.S. Dubin A.M. Balasubramanian S. et al.In-hospital arrhythmia development and outcomes in pediatric patients with acute myocarditis.Am J Cardiol. 2014; 113: 535-540https://doi.org/10.1016/j.amjcard.2013.10.021Google Scholar Approximately 20% of the institutions also reported adolescents with VAM who required respiratory support via nasal cannula. However, serious adverse outcomes were rare with only one institution reporting an adolescent who required extracorporeal membrane oxygenation support. The overall reported incidence of myopericarditis after administration of mRNA COVID-19 vaccine has been estimated to be 4.2 and 32.4 per million doses administered in female and male patients 12 through 17 years of age, respectively.2Centers for Disease Control and Prevention (CDC)Advisory Committee on Immunization Practices (ACIP).

Between December 2020 and mid-July of 2021, 9 million adolescents aged 12-17 years received Pfizer-BioNTech's mRNA COVID-19 vaccine. Postvaccination adverse effects were reported in 9246 adolescents (1/1000 recipients); however, more than 90% reports filed in VAERS were for nonserious symptoms such as dizziness, nausea, headache, and fever. Of the 863 serious adverse events, the most common reported conditions were chest pain, elevated serum troponin concentration, and myocarditis. Myocarditis was listed in 397 reports, representing 4.3% of all VAERS reports. Fourteen deaths were reported, the cause of 6 of which is still under investigation. No direct linkage to vaccination was reported in the rest.16Kuehn B.M.

Adolescent myocarditis after COVID-19 vaccination is rare.JAMA. 2021; 326: 902https://doi.org/10.1001/jama.2021.14237Google Scholar In addition, because the VAERS is critically dependent on reporting by practitioners and institutions, adverse events can be missed due to a lack of reporting. Our data, gathered from a large number of institutions across the US, provides an independent affirmation of the fact that serious life-threatening adverse events are extremely rare in adolescents with VAM. Previous reports have shown that electrocardiographic abnormalities are common in adolescents with VAM at the time of initial diagnosis4Das B.B. Kohli U. Ramachandran P. Nguyen H.H. Greil G. Hussain T. et al.Myopericarditis after messenger RNA coronavirus disease 2019 vaccination in adolescents 12 to 18 years of age.J Pediatr. 2021; 238: 26-32.e1https://doi.org/10.1016/j.jpeds.2021.07.044Google Scholar; however, only a handful were noted to have persistent abnormalities on 12-lead electrocardiogram or Holter monitoring suggesting that the electrocardiographic abnormalities noted in the acute phase are very likely to resolve within a few weeks. A majority of institutions indicated obtaining cardiac magnetic resonance imaging and an echocardiogram at follow-up visits; however, there was marked variability in the timing of these investigations. As per the current guidelines from the American College of Cardiology, athletes diagnosed with myocarditis should be restricted from exercise for 3-6 months to promote resolution of inflammation, especially if extensive inflammation is noted on cardiac magnetic resonance imaging.17American College of CardiologySport Recommendations for Athletes With Cardiomyopathies, Myocarditis, Pericarditis.https://www.acc.org/latest-in-cardiology/ten-points-to-remember/2019/07/19/08/37/recommendations-for-participation-in-competitiveDate accessed: August 22, 2021Google Scholar Previous studies have shown extensive myocardial involvement in adolescents with VAM in the absence of significant echocardiographic abnormalities.4Das B.B.

Only two-thirds of the institutions indicated considering a stress test before returning to full activity. Despite the observed variability in diagnosis and management, the short-term outcomes in adolescents with VAM were good and the majority recovered completely. Although treatment regimens differed, there was no significant difference in the lower (1.69 ± 0.84 vs 2.29 ± 1.3 days; P = 14) or the upper (5.41 ± 3.7 vs 4.1 ± 1.6 days; P = .27) limit of duration of hospitalization between those adolescents who were treated with only NSAIDs vs those who were treated with multidrug regimens. The variability highlighted by our study is reflective of the challenges faced by clinicians who were using their best judgement in the absence of robust guiding data. In the short-term, our data, which shows that life-threatening complications are extremely rare in adolescents with VAM, is quite encouraging and should motivate the population to receive COVID-19 vaccination. Our study had several limitations. Because this was a survey study, data for individual patients were not sought; therefore, the overall accuracy of data may not be comparable with an observational study. However, to enhance the quality of the data, the surveys were directed to physicians who directly participated in the care of adolescents with VAM. Several institutions had no or only a few adolescents with VAM. The responses from these centers might indicate diagnostic and treatment modalities which are likely to be used than the ones that were used. A majority of the participating centers were located in either the Midwest or the South. The responses could therefore reflect the prevailing practices in these geographic regions. Nevertheless, given the large number of centers that participated, our study does provide an estimate of various diagnostic and therapeutic aspects of VAM in adolescents across the US. If the responses of the institutions that responded were fundamentally different from the institutions that did not respond, this could bias the results. The response rate, however, is comparable with other survey studies that were conducted across a large geographic region.18Madaan P. Chand P. Linn K. Wanigasinghe J. Mynak M.L. Poudel P. et al.Management practices for West syndrome in South Asia: a survey study and meta-analysis.Epilepsia Open. 2020; 5: 461-474https://doi.org/10.1002/epi4.12419Google Scholar Because it is difficult to survey all providers, it is possible that patients with mild VAM could have been under-reported. Lastly, if the survey was completed by an infectious disease physician, the recognition of cardiology protocols may have been incomplete. Our study informs the need for consensus guidelines to help facilitate prompt diagnosis and optimal management of these adolescents. In addition, the findings of our study affirm that serious life-threatening complications due to VAM remain rare in adolescents. Data sharing statement available at www.jpeds.com.
