ABSTRACT
A first case of an unusual aortopulmonary window with tetralogy of Fallot associated with pulmonary atresia is presented. The aortopulmonary window was at the aortic sinus of Valsalva. The left aortic leaflet prevented pulmonary hypertension by occluding the window in systole.

In a patient with a large atrial myxoma, the phonocardiographic timing of the tumor plop has been correlated with the two-dimensional echocardiographic motion pattern of the cardiac mass. The tumor plop occurred at the time when the mass stopped its diastolic forward motion into the ventricle and made a strong impact on the interventricular septum and right ventricular posterior wall. Occurrence of tumor plop may require a large mass or long enough tumor stalk to allow the impact of the mass on the ventricular wall.
