Key result
Acute myopericarditis rarely presents as isolated RV failure and cardiogenic shock.
Why the study?
Myopericarditis is primarily associated with biventricular or left ventricular dysfunction, making isolated right ventricular failure an unusual and rarely recognized presentation.
Case Report (n=1)
Acute myopericarditis should be considered in the differential diagnosis of isolated right ventricular failure, even though it typically presents with biventricular or left ventricular dysfunction.

May warrant inclusion in isolated RV failure differentials; leaves open incidence and management in larger series.
Myopericarditis is characterized by pericardial and myocardial inflammation and is a known cause of chest pain and heart failure. It is primarily associated with biventricular or left ventricular dysfunction. We describe an unusual case of a 57-year-old woman with myopericarditis causing isolated right ventricular (RV) failure. She initially presented with chest pain and cardiogenic shock and was found to have acute RV dysfunction with a normally functioning left ventricle. After excluding more common causes of RV failure, she was diagnosed with acute myopericarditis. In this report, we discuss the differential diagnoses and work-up of acute RV failure, as well as review prior cases of RV-predominant myocarditis/myopericarditis. We highlight the importance of recognizing isolated RV failure as a possible, but rare, presentation of myopericarditis.

Ying et al. (2020) conducted a case report in Acute myopericarditis (n=1). Acute myopericarditis caused isolated right ventricular failure and cardiogenic shock in a 57-year-old woman, highlighting it as a rare but possible presentation of the disease.
