Some patients surviving an initial episode of coronary occlusion develop complications from myocardial necrosis which prolong their convalescence and decrease the likelihood of long-term survival. One of the more common and serious of these complications is ventricular aneurysm, occurring in from 10% to 38% of such patients.1,3,13,16 An aneurysm may appear as early as two days or as late as ten years after the infarction,10 and its development is favored by the presence of arterial hypertension, associated valvular disease, and inadequate bed rest after the initial heart attack.13 Paradoxical motion of the noncontractile aneurysm impairs left ventricular function and may result in cardiac failure which is frequently difficult, if not impossible, to control by medical measures alone. Mural thrombosis is common, and peripheral embolization may occur if a portion of this thrombus is dislodged.
In a collected series of 102 cases of ventricular aneurysm, Schlichter, Hellerstein, and
