The double outlet right ventricle with additional cardiac malformations: an anatomic and echocardiographic study

Abstract

Double outlet right ventricle (DORV) is a complex group of abnormal ventriculoarterial connections where both the aorta and pulmonary artery rise from the right ventricle morphologically. It is a rare condition affecting 1–1.5% of patients with congenital heart disease.
The patient’s cardiac measurements were taken by two-dimensional echocardiography. The pathological findings of the defined case are illustrated in the figures. A 20-year-old male patient with palpitations, tachypnea, and tiredness with weak exercise capacity and back pain was diagnosed with heart murmur in different degrees; slight cyanosis, cachexia, and developmental retardation were found clinically. Echocardiography showed: DORV, perimembranous ventricular septal defect, pulmonary stenosis, dilatated right ventricle, and dilatated left atrium. However, the left ventricle was normal. In addition, the septum interatriale filled the left atrium like an aneurysm.
DORV is an important and rare congenital cardiac malformation. This complex condition may result in different clinical findings and require different therapeutic approaches.
