[Coronary artery-cardiac fistulas. Review of the literature. Two accidentally discovered cases].

We report two cases of coronary artery fistula discovered accidentally during coronary-angiography. One case between the left anterior descending and the pulmonary artery and another case between the circumflex and the left ventricule. Both cases were associated with hypertrophic cardiomyopathy. There was a spontaneous closure of the fistula in the first case. A brief review of the literature is presented because this anomaly is being discovered frequently because of the possibility of diagnosis with transesophageal echocardiography.
