Abstract:
Among heart irregularities, congenital pericardial defect is an unusual anomaly, and is typically left dominant. However, cases of right pericardial defect with heart herniation are extremely rare. This is a case of congenital right pericardial defect with herniation of the right ventricle free wall and right ventricular outflow tract. The patient is asymptomatic and refused further intervention but even indolent discomfort underscores the risks of iatrogenic injuries to the heart and sudden death caused by mechanical pathogenesis due to changes in anatomical positions of the cardiac structures.
