Apparently isolated fetal mesocardia at midtrimester: report of a series

Severe subvalvular pulmonic stenosis due to a ball-shaped accessory tissue in an asymptomatic woman with congenitally corrected transposition of great arteries and mesocardia: A rare case report

Congenitally corrected transposition of great arteries (CCTGA) is a rare anomaly described by atrioventricular and ventriculoarterial discordance. On the other hand, mesocardia that is extremely rare includes two relatively well-defined apexes defined by each ventricle with the major axis of the heart lies in the midline. We describe a rare case of an asymptomatic 20-year-old woman with mesocardia, CCTGA, and severe subvalvular pulmonic stenosis due to a ball-shaped accessory tissue in left ventricular outflow tract.
