[Uncommon mechanisms of sudden death in chronic chagasic patients--report of 3 cases].

The case reports of three patients with chronic chagasic cardiomyopathy with unusual mechanisms of sudden death are presented. It was unexpected in two of them, one by infarction and the other by bronchopneumonia after gut infarction without mesenteric vessel obstruction. The third had cardiac failure and her expected sudden death was due to cardiac tamponade after spontaneous right ventricular rupture.
