Surgical Treatment of Coronary to Pulmonary Artery Fistulas in Adults

抄録

Coronary to pulmonary artery fistulas (CPAFs) are abnormal communications between the coronary and pulmonary arteries. They are an uncommon congenital heart disease and usually remain asymptomatic until later in life. However, there is no consensus on their management. We present four adult patients who required surgery for coronary to pulmonary artery fistulas to illuminate this issue. The clinical presentations were variable depending on the anatomical features of coronary to pulmonary artery fistulas and the presence or absence of other cardiac diseases. We successfully performed surgical closure of the coronary to pulmonary artery fistulas in each of the cases. In this report, we describe our experience with these cases and outline the available therapeutic strategies and treatment options for coronary to pulmonary artery fistulas.
