[Echocardiographic detection of persistent myocardial sinusoids].

In a 33-year-old woman the diagnosis of isolated persistent myocardial sinusoids could be established by 2-D-echocardiography and ventriculography. This anomaly has been reported in infants with atresia of semilunar valves and intact ventricular septum, or in combination with anomalies of the coronary vessels. In adults myocardial sinusoids have only been observed with a communication to the coronary arteries. To our knowledge, no other case of severe cardiac disease due to isolated myocardial sinusoids has so far been published.
