“…Blood flows from the left coronary artery via collaterals into the RCA and then retrograde into the pulmonary artery. Although the many patients are asymptomatic, one patient in this series had angina pectoris, and several patients have been reported with cardiac syncope, congestive heart failure, or sudden death (39)(40)(41). Ectopic origin of the LAD from the pulmonary artery is the rarest subtype.…”

Coronary artery anomalies were found in 1,686 patients (1.3% incidence) undergoing coronary arteriography at the Cleveland Clinic Foundation from 1960 to 1988. Of the 1,686 patients, 1,461 (87%) had anomalies of origin and distribution, and 225 (13%) had coronary artery fistulae. Most coronary anomalies did not result in signs, symptoms, or complications, and usually were discovered as incidental findings at the time of catheterization. Eighty-one percent were "benign" anomalies: 1) separate origin of the left anerior descending and circumflex from the left sinus of Valsalva; 2) ectopic origin of the circumflex from the right sinus of Valsalva; 3) ectopic coronary origin from the posterior sinus of Valsalva; 4) anomalous coronary origin from the ascending aorta; 5) absent circumflex; 6) intercoronary communications; and 7) small coronary artery fistulae. Other anomalies may be associated with potentially serious sequelae such as angina pectoris, myocardial infarction, syncope, cardiac arrhythmias, congestive heart failure, or sudden death. Potentially serious anomalies include: 1) ectopic coronary origin from the pulmonary artery; 2) ectopic coronary origin from the opposite aortic sinus; 3) single coronary artery; and 4) large coronary fistulae. Coronary artery anomalies require accurate recognition, and at times, surgical correction.

“…However, fistula to the pulmonary artery probably arises by supernumerary implantation of the developing coronary arteries into the pulmonary artery portion of the embryonic truncus arteriosus. This defect in embryologic coronary implantation may be related to that which causes an anomalous origin of the left or right coronary artery from the pulmonary artery [ 3 ] .…”

Bilateral coronary artery fistula constitutes an uncommon subgroup of coronary artery fistulas that may have a distinct embryologic origin. Coronary artery fistulas usually show a tortuous arrangement upon coronary angiography, but aneurysmal dilatation is rare. We report here an extremely rare case of coronary artery fistula originating from both coronary arteries, which showed multicystic aneurysmal dilatation.

“…RCA originating from the pulmonary artery has less clinical significance when compared to LAD and LCX, but clinical sequela still occurs. 11 Bland-White-Garland syndrome is an anomalous origin syndrome of LCA from the pulmonary artery. It is the most common type of coronary artery anomaly from the pulmonary artery.…”
