Combined double-chambered right ventricle with double-chambered left ventricle: a rare anomaly

Double-chambered right ventricle with double-chambered left ventricle is a very rare congenital anomaly. An 18-year-old female presented with dyspnea, chest pain, and palpitation. Diagnosis was made using transthoracic echocardiography and was confirmed by angiography. Surgical excision of the anomalous muscle bundles in the right ventricular outflow tract along with excision of the fibrous band from the left ventricle was performed. The postoperative course was uneventful and repeated echocardiogram before discharge showed a right ventricular outflow tract gradient of 8 mmHg, no gradient across the left ventricular cavity, and improved biventricular functions. The management strategy is dependent on presence of symptom, associated anomalies and type of pathology.
