[Cholesterol crystals pericarditis].

Cholesterol pericarditis is an uncommon, specific form of pericardial disease that is characterized by the presence of cholesterol crystals in pericardial fluid. The etiology may be either idiopathic or in association with systemic disorders such as tuberculosis, rheumatoid arthritis, myxedema or hypercholesterolemia. We report a case of cholesterol pericarditis in a 51-year-old male who was diagnosed with chronic renal failure due to polycystic kidney disease. To our knowledge no similar cases have been reported to date in the literature.

[Exercise-induced atrioventricular block. Significance of the ischemic component. Report of 4 new cases].

We report four new cases of exercise-induced atrio-ventricular block (appearing during treadmill exercise testing). The mechanism was ischemia in two patients and the conduction disturbance disappeared after coronary artery bypass grafting. The literature on this matter is reviewed. Also the etiology, the natural history and management are discussed in these cases.

[Right ventricular function and effort tolerance in patients with chronic congestive heart insufficiency. A cross-over double-blind study].

We tried to assess the value of both ventricular function changes and its correlation with maximal exercise capacity in patients with chronic heart failure. For this purpose, a double blind crossover study was designed, and the change in the exercise tolerance and both ventricular ejection fraction were evaluated. When compared with digoxin treatment (p less than 0.01) and with a control-period (p less than 0.001), the captopril increases total exercise time significantly. The response of right ventricular ejection fraction was similar. The changes in right ventricular ejection fraction, but not those of left ventricular ejection fraction, correlated with the variations of exercise time (r = 0.67). These facts suggest that right ventricular function is an important determinant of exercise capacity in patients with chronic heart failure and that its behaviour explain, in part, the response to captopril treatment.

[A primary epithelioid hemangioendothelioma localized in the pulmonary valve].

A case of epithelioid haemangioendothelioma sited at pulmonary valve, with an excrescence growing invading pulmonary artery troncus and its principal branches, in a 56-year-old woman is reported. The evolutive behavior simulated some clinical situations which made difficult the diagnosis: a mild-moderate pulmonary stenosis, a general syndrome, and, finally, an acute pulmonary thromboembolism that carried to an aggressive management which conducted to the entity diagnosis.
