Résumé : Coronary artery fistulas are rare anomalies and their association with a coronary aneurysm even more infrequent. We report two cases which are illustrative because of their different clinical presentations. In the first case the diagnosis was made after discovering fortuitously a heart murmur. In contrast in the second case the coronary artery fistula was demonstrated during a check-up for thoracic pain. In both cases the right coronary artery gave a fistulous communication to the right atrium.
