LV apex with horizontal dilatation of LV base (Fig. 1). Left ventricular angiography showed circular LV cavity due to obliterated apex with the central filling defect created by the hypertrophied papillary muscle, thus giving a classical "Doughnut" appearance during the diastolic phase of the cardiac cycle (Fig. 2).
Left ventricular angiography during the diastolic phase of the cardiac cycle. Circular appearance of the LV cavity due to obliteration of the apex with hypertrophied papillary muscle (arrow) causing a central filling defect gave the appearance of a "Doughnut".
