The authors report a case of pheochromocytoma in which the echocardiographic features suggested obstructive hypertrophic cardiomyopathy. The angiographic study and the computed tomography showed the tumor and its arterial supply. One month after resection of the tumor the echocardiographic features showed a tendency to normalization. The preoperative(More)
A six month-old infant presenting congestive heart failure and electrocardiographic features of acute myocardial infarction, including increased CK-MB levels. The echocardiographic study showed normal origin of the coronary arteries and features compatible with myocardiopathy. After good early response to conventional therapy, the patient developed severe(More)
PURPOSE The aim of the study was to analyse the role of 2D echocardiogram (ECHO) in the diagnosis of massive pulmonary embolism (PE), and in the follow-up after fibrinolytic or surgical treatment. METHODS Echocardiographic studies were retrospectively analysed in seven patients, 5 male, mean age 37 +/- 19 years, with massive pulmonary embolism (PE)(More)
Morpho-functional adjustments in the heart of juvenile tegu lizards (Tupinambis merianae) were analyzed at distinct seasonal periods to investigate how the demands of growth and of energy saving are reconciled during the first annual cycle. The relative ventricular mass (Mv) was 31% and 69% larger in late autumn and winter dormancy, respectively, compared(More)
Seasonal plasticity in the small intestine of neonatal tegu lizards was investigated using morphometry and analysis of enzymes involved in supplying energy to the intestinal tissue. In the autumn, the intestinal mass (Mi) was 1.0% of body mass and the scaling exponent b=0.92 indicated that Mi was larger in smaller neonates. During arousal from dormancy Mi(More)
Ebstein anomaly of the tricuspid valve is a well known malformation of the heart, but this occurrence in the mitral valve is a very rare congenital heart disease. In this case report a two years and nine months old girl with symptoms of heart failure during the first year of life due to severe mitral regurgitation was studied. The echocardiographic and(More)
The clinical suspicion of pulmonary artery aneurysm was made in two patients from the clinical signs and radiographic features. The echocardiographic studies showed features concerned with this pathology, and hemodynamic studies confirmed the diagnosis by pulmonary angiography. Both patients presented pulmonary valve insufficiency due to the huge pulmonary(More)
