[Aortic peri-valvular abscess, mycotic aneurysm of Valsalva sinus, and fistula to the right ventricle in a context of acute infectious endocarditis]. / Abcesso peri-valvular aórtico, aneurisma micótico do seio de valsalva e fístula para o ventrículo direito no contexto de endocardite infecciosa aguda.

Infective endocarditis continues to attract the attention of many physicians. The authors present a case report of a 64 year old man with a history of infective endocarditis of a native aortic valve complicated by a perivalvular abscess, mycotic aneurysm of a sinus of valsalva and acquired aorta-right ventricular shunt.

[Cardiac amyloidosis: review of the literature]. / Amiloidose cardíaca: revisão da literatura.

The authors review the clinical impact of cardiac amyloidosis and new aspects concerning the management of this disease in the literature. Cardiac amyloidosis accounts for 5-10% of non-coronary myocardial disorders. It is a distinct form of cardiomyopathy with a severe prognosis. The authors review the role of endomyocardial biopsy and the relative sensitivity of non-invasive diagnostic methods. Chemical and genetic typing of amyloid, which is of considerable clinical value, is also reviewed due to recent evidence of treatment for different types of systemic and cardiac amyloidosis, such as the most common hereditary form caused by transthyretin gene mutation.
