It forms a small part of the sternocostal surface and a considerable part of the diaphragmatic surface of the heart it also forms the apex of the heart.

Orphan date February 2009 A double inlet leftventricle DILV is a congenital heart defect where both the left atrium and the right atrium feed into the leftventricle . Usually a hypoplastic right ventricle also exists the condition is sometimes referred to as single ventricle . The arteries are usually transposed the aorta from the right ventricle, and the pulmonary artery from the leftventricle . Effects Infants born with DILV have excessive blood flow to the pulmonary circulation. They cannot feed normally and have difficulty gaining weight. Excessive pulmonary circulation leads to decreased systemic circulation lack of oxygen to the body and organs . Infants develop cyanosis and or breathlessness early. Treatment This treatment is usually treated with surgery. Surgical options include the Damus Kaye Stansel Procedure, the Fontan procedure , and the Norwood procedure . The goal of all of these is separating the pulmonary and the systemic circulation. Category Congenital heart disease ... more details
