A Reappraisal Based on a Study of Sixty-Five Consecutive Autopsied Cases
Sixty-five consecutive autopsied cases of ventricular aneurysm are reviewed. The incidence of aneurysm following myocardial infarction is similar to that reported in other series. Myocardial infarction preceded the formation of an aneurysm of the ventricle in the vast majority of patients, and a new myocardial infarction was the cause of death of about 50 per cent of them. The survival rate of patients with ventricular aneurysm is not significantly different from the long-term survival of all patients with myocardial infarction found in the same institution. Complications of ventricular aneurysm such as chronic congestive heart failure and rupture of the aneurysm were infrequent causes of death, and systemic embolic phenomena were not observed as a cause of death. In only four patients was the diagnosis made ante mortem. The lack of characteristic clinical, radiologic, and electrocardiographic findings is discussed. It is suggested that the hemodynamic significance of ventricular aneurysms is not ordinarily great, in view of the unaffected statistical prognosis in its presence. The recommended indications for surgery of ventricular aneurysms, based on this retrospective study, are presented.
