[Sudden death and tachycardiomyopathy in a young man with incessant tachycardia]. / Morte súbita e taquicardiomiopatia em jovem com taquicardia incessante.

The case of a 19-year-old young man with clinical picture of congestive heart failure and supraventricular tachycardia is reported. Heart failure got better with conventional treatment, but the tachycardia persisted in spite of antiarrhythmic drugs. Echocardiogram showed dilated cardiomyopathy of important degree and the endomyocardial biopsy, mild interstitial infiltration. Scintigraphy with gallium 67 was normal. Twenty days after the patient leaving the hospital, suffered sudden death. It is discussed the hypothesis that patient had developed a tachycardiomyopathy secondary to the incessant tachycardia. The importance of the diagnosis is reinforced by possibility of reversion of the cardiomyopathy by the resection of the anomalous pathway.

[Jaccoud's syndrome. A case report]. / Síndrome de Jaccoud. Relato de caso.

The study concerns a 44 year-old male patient with a history of intermittent episodes of rheumatic activity; the physical examination showed mitral valve stenosis and metacarpophalangeal joint deformities. The joint deformities were bilateral and symmetrical, similar to that of rheumatoid arthritis. Nevertheless, the ulnar deviation of the hands was reversible and there were no typical signs of rheumatoid arthritis in the X-ray. In view of the facts, the diagnosis of Jaccoud's Artrhopathy (JA) was made. The pathogenesis, the clinical features and the association between mitral valve stenosis and joints deformities of JA are discussed. This disease has a good prognosis and it is sparsely mentioned in the cardiologic literature. Many patients with JA are diagnosed as having rheumatoid arthritis, which is a chronic and disabling disease.
