A series of 13 cases of ischemic heart disease, proved by coronary angiography, were submitted to ventriculography in order to study the hemodynamic consequences of the injection of the contrast material. The parameters used to evaluate the ventricular function were the end diastolic pressure, the dp/dt, the VEC and the V. max. A close relationship was(More)
Clinical, laboratory and electrocardiographic data from 608 patients with permanent pacemakers implanted over a period of 8 years, were evaluated retrospectively. The number of implants was greater in males (56.5%) and in patients over 60 years of age (77.5%). Atherosclerosis was the most common disease found in this group (50%). Syncope occurred in 96.2%(More)
We studied 400 cases of isolated atrial septal defect without severe pulmonary hypertension, in which the diagnosis was established by the hemodynamic data and it was proven by surgical findings in 257 instances. High fidelity unipolar thoracic and intracardiac records, as well as vectorcardiographic curves in three planes, were obtained. Different types of(More)
A modified Rackley et al technique for left ventricular mass calculations is applied to patients with concentric hypertrophy originated by hypertensive cardiopathy and to normal subjects. The values found in 8 normal subjects were 41 +/- 16 g/m2 of body surface and in 20 patients with hypertensive cardiopathy were 63 +/- 20 g/m2 (p = 0.01). The results(More)
Fibrous sub-aortic stenosis in 19 patients surgically treated is discussed. The clinical, radiologic, EKG and cardiac catheterization data in the pre and post-operative evaluations are reviewed. There were no surgical deaths in this series. In 14 cases post-operative cardiac catheterization was carried out, in 11 patients a significant decrease in the(More)
