[Apical hypertrophic cardiomyopathy and coronary arteriovenous fistula].

We present a case of association of apical hypertrophic cardiomyopathy of the Japanese type and coronary arteriovenous fistula in a 56-year-old male who presented with anginal symptoms. Both cardiopathies can produce myocardial ischemia and angina, and their association could aggravate the ischemia. In our patient the symptoms were adequately controlled with Verapamil. The coexistence of these two rare entities in the same patient has recently been described in 2 other cases, allowing us to speculate on a possible etiological relation between the 2 abnormalities, probably both been originated in a common developmental error.
