In 30 patients, simultaneous measurements of ascending aortic pressure and diameter were performed, allowing one to evaluate: (1) the influence of age, the aortic diastolic pressure, and the radius on the aortic elasticity; (2) the correlations between characteristics impedance of the aorta (Zo), systemic arterial resistance, age and diastolic aortic(More)
The association of dynamic left ventricular outflow tract obstruction and pheochromocytoma is rare with only about fifteen previously reported cases in the literature. The association may be the result of chronic increased catecholamine secretion which induces intra-ventricular obstruction in a hypertrophied ventricle due to hypertension. The authors report(More)
The association of a myocardial bridge of the left anterior descending (LAD) coronary artery and myocardial infarction is rare. The mechanisms by which the myocardial bridge could predispose to myocardial infarction are tachycardia (reducing the duration of diastolic coronary filling), thrombosis at the site of the myocardial bridge, and coronary spasm(More)
In this study of 61 patients (group I: 37 patients with no signs of cardiac failure, group II: 24 patients with signs of cardiac failure), a comparison is made between the indices of left ventricular performance obtained during the isovolumic phase dp/dt/Pt max of the left ventricle (5F Millar micromanometer) and in the ejection phase (ejection fraction,(More)
The aim of this study was to determine whether the percentage of akinesia on echocardiography during the acute phase of transmural anterior myocardial infarction could predict secondary left ventricular dilatation. The study group comprised 24 patients (18 men and 6 women) with an average age of 59 years. The patients underwent two echocardiographic(More)
A case of painless anteroseptal and high lateral wall infarction presenting as cardiogenic shock with pulmonary oedema 24 hours after childbirth complicated by severe post partum haemorrhage with a coagulation defect, is reported. Coronary angiography performed one month later was normal, with a negative ergometrine provocation test. The authors review five(More)
