Insights
This case report describes a 58-year-old man with new-onset atrial fibrillation and heart failure due to COVID-19-associated myocarditis. The findings emphasize that cardiac symptoms can occur without typical coronavirus disease 2019 symptoms.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Imaging
Background:
- Coronavirus disease 2019 (COVID-19) can cause various cardiac complications.
- Myocarditis, inflammation of the heart muscle, is a recognized but less common manifestation of COVID-19.
Observation:
- A 58-year-old man presented with palpitations and dyspnea, diagnosed with new-onset atrial fibrillation and severely impaired left ventricular systolic function (ejection fraction 20%).
- Cardiac MRI revealed generalized severe myocarditis.
- SARS-CoV-2 PCR testing was positive.
Findings:
- The patient was diagnosed with COVID-19-associated myocarditis based on cardiac MRI findings and a positive SARS-CoV-2 test.
- This case demonstrates that COVID-19-associated myocarditis can manifest with new atrial fibrillation and heart failure.
Implications:
- This case highlights the importance of considering COVID-19-associated myocarditis in patients presenting with new cardiac arrhythmias and heart failure, even in the absence of classic COVID-19 symptoms.
- Early diagnosis and management of COVID-19-associated myocarditis are crucial for improving patient outcomes.
Abstract:
A 58-year-old man presented to the emergency department with recent-onset palpitations and progressive exertional dyspnoea. ECG demonstrated new-onset atrial fibrillation. Transthoracic echocardiogram showed global impairment in left ventricular systolic function with left ventricular ejection fraction of 20%. Cardiac MRI (CMRI) demonstrated generalised severe myocarditis. A SARS-CoV-2 PCR was positive for SARS-CoV-2 RNA. As such, we diagnosed our patient with COVID-19-associated myocarditis based on CMRI appearances and positive SARS-CoV-2 swab. This case highlights that COVID-19-associated myocarditis can present as new atrial fibrillation and heart failure without the classic COVID-19-associated symptoms.
