[Congenital coronary artery malformations and associated clinical syndromes (author's transl)].

In 34 cases, corresponding to 3,7% of all patients underwent coronary arteriography for evaluation of anginal syndrome in our laboratory, it was observed a congenital coronary anomaly on their angiograms. The purpose of this paper is to verify the frequency of coronary anomalies and to evaluate relations existing between these anomalies and anginal syndrome. Coronary arteriograms, in 22 cases (2,44%), revealed exclusively; the presence of a coronary anomaly without occlusive coronary disease, which might per se justify angina. They were distributed as follows : 5 with coronary fistula, 2 with coronary aneurysms, 2 cases with single ostium and finally, 13 subjects with hypoplasia of one of the three major coronary arteries. One infant, 14 months old, had a hyperplasic left discending artery (LDA) draining in right ventricle cavity. Her ECG revealed signs of right ventricle overload. All the other cases had a typical angina syndrome with positive stress test. Left cineventriculography demonstrated left ventricle asynergy in 16 patients. We concluded that typical angina syndrome in our 22 patients, may be attributable to coronary anomalies observed at their coronary arteriograms.
