2024年6月22日 · Major aortopulmonary collateral arteries (MAPCAs) are congenital cardiac lesions that result from persistent embryonic connections between the aorta or its branches and the pulmonary vascular system (see Image.

Major aortopulmonary collateral arteries (MAPCAs) are congenital heart defects consisting of nonregressed systemic-to-pulmonary embryologic connections from the aorta or its branches to the pulmonary arterial vasculature.

2018年8月13日 · One-day old female with major aortopulmonary collateral arteries (MAPCAs), a rare type of congenital heart defect. Normally, the pulmonary arteries pump blood from the right ventricle of the heart to the lungs for oxygenation.

Major aortopulmonary collateral arteries (or MAPCAs) are arteries that develop to supply blood to the lungs when native pulmonary circulation is underdeveloped.

2022年2月3日 · Major aortopulmonary collateral arteries (MAPCAs) are congenital heart defects consisting of nonregressed systemic-to-pulmonary embryologic connections from the aorta or its branches to the pulmonary arterial vasculature.

2020年12月5日 · In this report, which is the most comprehensive evaluation of pulmonary vascular anatomy in patients with TOF/MAPCAs, we described the highly variable anatomy of >1000 MAPCAs and central PA configurations in 276 infants, providing novel insight into the distribution and constellation of anatomic features in this population.

2021年4月23日 · Major aortopulmonary collateral arteries (MAPCA) occur in cyanotic congenital heart diseases with decreased pulmonary blood flow (tetralogy of Fallot like physiology). They are a natural protective mechanism to improve pulmonary blood flow. MAPCAs are more likely to occur in pulmonary atresia than in simple tetralogy of Fallot.
