Abstract:
A congenital partial defect of the right-sided pericardium is a rare cardiac anomaly and it represents
defective formation of the pleuropericardial membrane. Patients can be asymptomatic, but they may
experience chest pain, myocardial ischemia, emboli, arrhythmia, and sudden death. In this report,
we present an 8-month-old boy with pericardial defect and right atrial appendage herniation. It was
diagnosed by echocardiography and cardiac magnetic resonance imaging.
