conclusions the coronary sinus flow per minute is the most accurate parameter among the three echocardiographic parameters mentioned above for the assessment of significant stenosis of the coronary artery. results flow (ml/minute), flow/lvm (ml/minuteg) and lv (d-s) mass a-l all correlated significantly with the percentage of stenosis (r = -0.64, p < 0.001; r = -0.47, p < 0.001; r = -0.56, p < ...

background: coronary disease is the most common cause of death in the world. because of common risk factors, atherosclerotic stenosis of coronary and carotid arteries occurs together. this study evaluated the prevalence of carotid stenosis in diabetic candidates for angiography methods: in a cross-sectional study, 152 diabetic candidates for angiography referred to cardiology clinic of shariati...

During 15 years from 1975 to 1990, thirteen cases of supravalvar aortic stenosis were admitted at the pediatrics department of Shahid Rajai Heart Hospital, Tehran. All patients were subjected to cardiac catheterization and a angiocardiography. Patients ranged in age from 3.5 years to 14 years with a mean of 8.7 years. Seventy seven percent of childen were male. Eight cases (61.5%) had Wil...

AIM The aim of this study was to investigate whether there was an association between the degree of the stenosis of the internal carotid artery (ICA) and post-operative increase of blood flow. METHODS AND MATERIALS In 200 out of 660 patients undergoing carotid endarteriectomy (CEA) for a high-degree ICA stenosis, pre-operatively a bilateral selective carotid and intracerebral angiography was ...

Arterial stenosis, for example Atherosclerosis, is one of the most serious forms of arterial disease in the formation of which hemodynamic factors play a significant role. In the present study, a 3-D rigid carotid artery with axisymmetric stenosis with 75% reduction in cross-sectional area is considered. Laminar blood flow is assumed to have both Newtonian and non-Newtonian behavior (generalize...

Introduction: Meatal stenosis is a recognized complication of circumcision done during nappy aged boys as a late presentation. The objective of this study was to describe the incidence of documented meatal stenosis in boys circumcised in infantile period. Method: Meatal stenosis was defined as change in appearance of the delicate lips of the urinary meatus, with loss of ellipticated shape to a...

This study evaluated the relationship between the location of the most severe coronary artery stenosis and the subsequent acute myocardial infarction (AMI). Methods: Of 1590 patients who were admitted with a diagnosis of AMI, we identified 44 patients who had undergone previous myocardial perfusion SPECT. Thirty-one of these patients also had previous coronary angiography. The relationshi...

Prostaglandin E1 (alprostadil) is widely used for maintaining the patency of ductus arteriosus in ductus-dependent congenital heart defects in neonates to improve oxygenation. Among more common side effects are fever, rash, apnoea, diarrhoea, jitteriness, and flushing. More severe side effects are brown fat necrosis, cortical hyperostosis, and gastric outlet obstruction, most commonly the resul...
