Single ventricle

A ventricular congenital heart disease

Single ventricle is a rare congenital heart defect, which constitutes just over 1% of congenital cardiovascular diseases. The single functional ventricle could be morphologically right or left with the second ventricle usually hypoplastic and/or insufficiently functional. Therefore, there are several subtypes of the disease, depending on which ventricle is underdeveloped.Single ventricle with functional left ventricle: Pulmonal atresia Tricuspidal atresia Double inlet left ventricle Double outlet left ventricle Single ventricle with functional right ventricle: Hypoplastic left heart syndrome Double inlet right ventricle Double outlet right ventricle Single ventricle heterotaxy syndrome is also included to this category.
