To study the relationship between global and regional filling of the left ventricle, we conducted resting gated radionuclide ventriculographic studies in 15 control subjects (group 1) and 22 patients with isolated disease of the left anterior descending coronary artery (group 2). None had had a previous myocardial infarction. A computer program subdivided(More)
To determine the presence and prevalence of regional contraction abnormalities in patients with angina pectoris, radionuclide ventriculography gated to an electrocardiogram was carried out in 22 control subjects (group 1) and in 22 patients with angina pectoris (group 2) with isolated stenosis of the left anterior descending coronary artery. No patients had(More)
Numerous surgical approaches have been used to treat petrous apex cholesterol granulomas. They are usually treated via the transtemporal- or middle fossa approach; some are managed endoscopically. We present a patient treated by the endoscopic transsphenoidal approach and review the literature.
To assess left ventricular (LV) systolic and diastolic function globally and regionally and to study the relationship between regional asynchrony and global LV function in patients with stable effort angina pectoris (AP) without previous myocardial infarction, we conducted a resting gated radionuclide ventriculographic study in 15 control subjects (N group)(More)
We developed a new echocardiographic approach to detect the interatrial septum (IAS) by tilting a transducer leftward, cephalad and backward from the right subcostal area. This technique could allow us to visualize the IAS moving perpendicularly to the ultrasonic beam. In normal subjects the IAS showed a small posterior deflection moving toward the left(More)
