[Congenital coronary fistula. Clinical presentation in 7 cases and literature review].

Unlabelled: Congenital coronary artery fistulas are uncommon anomalies, however themselves may resemble the whole spectrum of cardiac manifestations. Clinical presentations vary considerably from adults to children.

Material And Methods: patients with coronary artery fistula diagnosed by selective coronariography in the period from 2000 to 2007 were included.

Results: 7 cases were found, 4 children, mean age 6.5 years, and 3 adults, mean age 25.6 years. The fistulae originate from the left coronary artery in 3 children, 2 connect to the pulmonary artery an one to the right atrium, in one child the fistula originated from the right coronary artery and terminated at the right ventricle. In the 3 adult patients, the fistula originated from the right ventricle, two connected to the right ventricle and one to the coronary sinus. Two children were operated on successfully and are asymptomatic 1 and 4 years later. In an adult patient with surgical ligation was performed, 4 weeks later developed an uncomplicated myocardial infarction. We reviewed the literature available and were compared with our cases.

Conclusions: The clinical manifestations and hemodynamic features differ in childhood and adulthood. Coronary angiography is the primary diagnostic tool. Surgical treatment has low mortality and morbidity.
