Abstract
Coronary to Pulmonary Artery Fistula as a Main Source of Pulmonary Blood Flow in Pulmonary Atresia and Ventricular Septal Defect
Highlights
Pulmonary atresia with ventricular septal defect is associated with variable aortic to pulmonary arterial connections
Coronary artery to pulmonary artery collaterals are rare sources of pulmonary blood flow, and when present, they are associated with other major aortopulmonary collaterals, and will have no significant proximal coronary artery dilatation [1,2]
We report a 21-year-old female patient with a diagnosis of pulmonary atresia and ventricular septal defect
Summary
Aortic root angiography showed severely dilated left coronary sinus and left main coronary artery, with a tortuous, spiral-like fistulato pulmonary trunk that comprised most of pulmonary blood flow. Pulmonary atresia with ventricular septal defect is associated with variable aortic to pulmonary arterial connections. Coronary artery to pulmonary artery collaterals are rare sources of pulmonary blood flow, and when present, they are associated with other major aortopulmonary collaterals, and will have no significant proximal coronary artery dilatation [1,2]. We report a 21-year-old female patient with a diagnosis of pulmonary atresia and ventricular septal defect.
