Comunicación entre la arteria coronaria derecha y la aurícula derecha

Abstract

Two cases of anomalous communication of the right coronary artery with the right atrium (the so-called coronary artery fistula) are presented. Both were young females in which a continuous murmur was heard during routine examination. The x-ray image was typical, with a huge bulge in the right border similar to that seen in cases of right atrium enlargement. The ECG was normal in both patients. The diagnosis was made during cardiac catheterization and angiocardiography. A slight left-to-right shunt was present and the aneurismatic dilatation of right coronary artery and communication with the right atrium could be documented. In both cases a surgical closure of the defect was performed, both being well after two years and eight months respectively.
