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

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.

Absence of the musculocutaneous nerve together with unusual innervation of the median nerve.

During routine anatomical dissections, absence of the musculocutaneous nerve was determined in a 58-year-old male cadaver. Moreover, the biceps brachii and brachialis muscles were innervated by two separate branches which divided from the median nerve instead of the musculocutaneous nerve. From a branch that divides from the main trunk of the median nerve at nearly the middle of the arm a motor branch again divided that innervated the brachialis muscle and a sensory branch that conveyed the sense of the lateral part of the forearm. Furthermore, it was found that the brachial artery divided into its terminal branches, the radial and ulnar arteries. We believe that this rare variation of the median nerve will shed light upon surgical procedures involving the median nerve.
