Sudden death due to left ventricular thrombosis: A report of two autopsy cases.

PURPOSE

In this paper, we report two rare cases of sudden death due to giant left ventricular thrombus revealed at autopsy and we discuss the manner and the cause of death.

RESULTS

Cases presentation: The two cases reported are about two men aged 55 and 53 years respectively. In the two cases, no past cardiac history was found. Prior to the onset of complications and subsequent death, both patients presented to the emergency department with progressing asthenia, faintness and shortness of breath, were treated symptomatically. At autopsy, atherosclerosis of coronary arteries was found. In the first case, death was attributed to thrombosis of the pseudoaneurysm. In the second case, it was due to thrombosis complicating a myocardial infarction. The mechanism of death in the first case was explained by the hemodynamic shock caused by a total left ventricular pseudoaneurysm thrombosis secondary to old myocardial infraction. In the second case, death was the consequence of a cardiogenic shock secondary to thrombosis of the cardiac pseudoaneurysm complicating a myocardial infraction.

CONCLUSION

Complications of myocardial infarction represent frequent causes of adult sudden death. Left ventricular thrombosis is a complication that is often fatal and its discovery during an autopsy remains rare. The first-line doctor must take these types of complications into consideration in order to detect them and thus ensure timely management.
