[Arteriovenous fistula and rheumatic cardiopathy].

A case of pulmonary arteriovenous fistula associated with rheumatic mitral heart disease is presented. We have reviewed the literature and no published case with such association has been described. The loud mitral insufficiency murmur hide the continuous murmur of the fistula. The angiographic study demonstrated the A-V fistula. Retrospectively the diagnosis should have been suspected due to cyanosis, slight clubbing, the radiologic findings and the important Qs/Qt shunt. The associated pulmonary embolic phenomena made more difficult the diagnosis.

[Circulation disorders in infectious endocarditis].

80 autopsy cases with the diagnosis of infectious endocarditis were reviewed from the Department of Pathology of the Instituto Nacional de Cardiología. Cases included were those who had history of conduction abnormalities. 5% of cases had conduction abnormality due to infectious endocarditis. In 12% of cases, this was attributed to some other cause independent of IE. Only 2 cases had complete AV block and in one of them (1.25%) there was a ventricular septal lesion. It was concluded that abnormalities are a least frequent complication in the natural history of IE. Generally it is due to the extension of the infectious process in the aortic valve towards the ventricular septum and when present carries a bad prognosis.
