Indispensable Role of Transesophageal Echocardiography in Double-Chamber Right Ventricle Repair Surgery

Double-chambered right ventricle in a patient with pulmonary atresia and ventricular septal defect

Double-chambered right ventricle is a rare form of right ventricular outflow tract obstruction caused by anomalous hypertrophy of muscle bundles in right ventricle. Cases most often occur in children and rarely in adults. Most cases (80-90%) are associated with ventricular septal defect. We describe a case of pulmonary atresia and ventricular septal defect with double-chambered right ventricle. The interesting clinical findings, ECG, echocardiography and angiocardiography features are described here.
