2022年9月19日 · Aortic valvular atresia is a severe congenital condition characterized by the fusion of the aortic valve cusps at birth, obstructing the left ventricular outflow tract. The anomaly can present as subvalvular, valvular, or supravalvular, often existing within the hypoplastic left heart syndrome spectrum.

2022年8月9日 · Aortic valve atresia is one of the rare anomalies of the heart present at birth due to the fusion or closure of the aortic valvular cusps, which compromises the blood flow from the left ventricle into the aorta. It is a common cause of fatality in neonates with heart problems.

2022年9月19日 · Aortic valvular atresia is a congenital condition in which the aortic valvular cusps are fused at birth. This condition frequently forms a spectrum of left ventricular outflow tract malformations. The atresia can be characterized as subvalvular, valvular, or supravalvular, depending on the site of t …

2023年9月9日 · Aortic valvular atresia occurs when the flaps of the aortic valve are fused at birth, causing the right ventricle to be larger than normal and the left ventricle to be significantly smaller than normal. Having an undersized left ventricle deprives the body of adequate oxygen-rich blood.

Severe left outflow tract obstruction (LVOTO) is not always associated with hypoplastic left heart syndrome (HLHS). Aortic valvar atresia or complex LVOTO in the presence of a large ventricular septal defect (VSD) are a rare group of lesions that offer the possibility of biventricular repair.

Aortic atresia with a normal left ventricle and normal mitral valve is an uncommon congenital lesion. We present two such cases and describe two different approaches of achieving biventricular surgical repair.

Atresia (ah-TREE-zhah) is a condition in which a baby is born with a missing or closed valve or tube somewhere in his or her body. Aortic atresia is a rare defect that involves valves in the heart. More to Know

Typical anatomic features of aortic atresia with normal left ventricle include a tiny ascending aorta, a large pulmonary artery and patent ductus arteriosus, a coarctation, and a posterior malalignment VSD. Incisions used for the repair are noted.

Aortic valve atresia is one of the most rapidly lethal forms of congenital cardiac disease, accounting for twenty-five percent of cardiac deaths during the first week of life. I. 2 The majority of infants with aortic atresia are dead within six weeks of life with current medical management, and prolonged survival after a reparative operation has...

2019年7月7日 · Aortic stenosis and atresia encompass a group of congenital heart diseases (CHDs) characterized by left outflow tract obstruction. It accounts for 3% of all CHDs. There is a 15% recurrence risk, one of the highest regarding CHD.
