Double-Outlet Right Ventricle, Atretic Pulmonary Valve, and Subaortic Ventricular Septal Defect
A 22-year-old woman was referred to our clinic because of multiple abortions. She had dyspnea on exertion (functional class II). Physical examination revealed an early diastolic murmur in the aortic area. The O2 saturation of the patient was 83 % by pulse oximetry in room air. Electrocardiography showed normal sinus rhythm, right axis deviation, and equal R and S in lead V1. Chest X-ray revealed hypovascularity of the lungs and cardiomegaly. Transthoracic echocardiography showed normal left ventricular size and mild systolic dysfunction, normal right ventricular size and function, and mild mitral and tricuspid regurgitation with a tricuspid regurgitation gradient of about 70 mmHg.
