TOPIC: Cardiovascular Disease TYPE: Medical Student/Resident Case Reports INTRODUCTION: Viral Myocarditis is generally a self-limiting condition. Patients usually recover from viral myocarditis within a few weeks to months. Some patients can develop hemodynamic instability and may require critical care management. We present a unique case of acute systolic heart failure secondary to Coxsackievirus myocarditis which recovered within a few days. CASE PRESENTATION: A 19-year-old male came to ER for vomiting and abdominal pain for five days. Initial vitals were Temperature of 98 F, BP of 80/47 mm Hg HR of 124/min, and oxygen saturation of 93% on room air. EKG showed sinus tachycardia without ischemic changes. Initial labs were creatinine-2.6 mg/dl, troponin-2.15 ng/ml. CT of abdomen was unremarkable. CT of chest showed bilateral pulmonary edema and pleural effusion. Lung perfusion scan showed no perfusion defect. He did not respond to intravenous(IV) fluid. Initially it required IV vasopressor support- norepinephrine, phenylephrine, and dobutamine. Echocardiogram showed ejection fraction(EF) of 20-24% with severe global hypokinesis. COVID-19 PCR was negative. The pleural fluid study revealed transudative in nature. On day 3, he was weaned off from vasopressors. Acute kidney injury also resolved. Cytomegalovirus, HIV, autoimmune panel, and respiratory virus panel were negative. Coxsackievirus antibody came back positive. It was consistent with viral myocarditis. Patient showed clinical improvement, and we decided to repeat echocardiogram before discharge. On day 6, repeat echocardiogram showed significant improvement of EF to 54%. The patient was discharged on low dose carvedilol and lisinopril. Clinic follow up showed the patient's significant clinical recovery within a few weeks. DISCUSSION: In case of severe cardiomyopathy secondary to viral myocarditis, patient generally recovers within a few weeks to months. However, in our case, the patient developed acute systolic heart failure from Coxsackievirus myocarditis recovered within a few days after aggressive hemodynamic support. Repeat echocardiogram on the same admission also showed significant improvement in ejection fraction from 24% to 54%. It is a rapid recovery as per our knowledge and published data. CONCLUSIONS: Our case highlights that viral myocarditis has the potency to recover quickly, even from severe systolic dysfunction. This case also emphasizes the importance of repeating an echocardiogram on the same admission rather than waiting for a couple of months to ensure cardiac function recovery, particularly with very low ejection fraction on presentation.
