Single Ventricle, Malposition of Great Arteries, and Valvular and Subvalvular Pulmonary Stenosis
A 16-year-old female referred to our center for the evaluation of cyanosis. She was a known case of congenital heart disease from childhood. She had easy fatigability and dyspnea on exertion (functional class II). Physical examination revealed an ejection systolic murmur at the left sternal border and apex with maximal intensity in the pulmonic area. Electrocardiography showed normal sinus rhythm and normal axis deviation with no evidence of right ventricular hypertrophy. Chest X-ray demonstrated an increased cardiothoracic ratio and dilated pulmonary artery branches.
