title: [Coronary vessel anomaly: fistula between the right coronary artery and the left ventricle clinically presenting as aortic valve insufficiency (author's transl)].
abstract: Under more than 200 cases of coronary vessel anomalies only 33 are fistulas from the right or left coronary artery into the left ventricle. The case presented here of a fistula from the right coronary artery into the left ventricle featured the clinical picture of an aortic valve insufficiency. The histologic findings support the theory that these fistulas are embryological anomalies: transient communications between the ventricular trabeculas and the coronary vessels may be lined with endothelium and become then persisting as fistulas.
