[Congenital coronary aneurysm. Three case reports].

Congenital coronary aneurysms are an unusual anatomical entity. Their prognosis appears to be particularly dependent on the presence or absence of aneurysm thrombosis. We report three cases of congenital coronary aneurysms, diagnosed in one case after myocardial infarction.

[Pacemaker infections].

Infectious complications following pacemaker implantation are not common but can be particularly severe. The reported incidence varies from 0.5 to 5% in the literature.

[Mitral valve prolapse and sudden death: a case report].

Mitral valve prolapse (MVP) is a common disorder that, in general, has a good prognosis. Rare occasions of sudden death have been reported in patients with MVP and it is presumed that the basis of sudden death is arrhythmias. We report a case of a 47 years old men affected by MVP complicated by ventricular arrhythmias and sinoatrial block; who died suddenly from ventricular tachycardia.
