[A complete atrioventricular block and polymorphic ventricular tachycardia as the initial manifestation of secondary amyloidosis]. / Bloqueo auriculoventricular completo y taquicardia ventricular polimorfa como manifestación inicial de amiloidosis secundaria.

Cardiac injury is a frequent characteristic in primary, senile and myeloma related amyloidosis, but it is unusual in secondary amyloidosis. We report a patient with complete atrioventricular block and polymorphic ventricular tachycardia as the initial manifestation of secondary amyloidosis. Necropsy demonstrated amyloidosis deposits in the specific conduction system.

Myocardial abscess at a distant zone from the active valvular infection.

A case of an infective endocarditis with myocardial abscess due to Streptococcus anginosus at a distant location from the active valvular infection is reported. We conclude that local cardiac suppurative complications can appear in the evolution of endocarditis caused by this virulent organism.
