Echocardiographic features of a patient with sinus of Valsalva aneurysm rupture into the right atrium are described. The aneurysm presented as a dense echo-producing mass in the right atrium which descended into the tricuspid orifice during diastole and withdrew back into the atrium during ventricular systole. Pulmonic valve exho motion demonstrated early diastolic pulmonic valve opening indica...

high blood pressure has become increasingly commonbetween people and also it takes a major risk factor for many diseases. the present study is done toperformthe collaborative care model in patients with high blood pressure. hypertension is defined as: systolic blood pressure (sbp) ≥140 mmhg or diastolic blood pressure (dbp) ≥90 mmhg .a collaborative care model is a native educating method based...

AUTHORS' SYNOPSIS In dogs the effects of acute myocardial infarction (AMI) on right and left heart pressure relationships were studied. Right atrial pressure was a poor predictor of left heart pressures. Pulmonary artery end-diastolic, left atrial, and left ventricular end-diastolic pressures tended to equalize in normals (except with tachycardia) and after AMI. In a previously scarred left ven...

whilst there seem to be available data on blood pressure profiles of south african children, especially in urban areas, few data exist on rural children. the aims of this study were to determine the blood pressure profiles of rural south african children residing in thohoyandou; and to examine the relationship between body mass index and blood pressure among the children.the study involved 296 ...

background : sleep apnea is accompanied by some cardiovascular complications. it has even been hypothesized that sleep apnea, itself, can induce some of these complications. given such controversies, we assessed the left ventricular mass index (lvmi) and systolic pulmonary artery pressure in patients with sleep apnea. methods: through convenience sampling, 56 patients with the obstructive sleep...

AIM To characterize the buffering function of the pulmonary artery in vivo and to determine the role of vascular smooth muscle (VSM) activation in vessel wall elasticity. MATERIAL AND METHOD Pulmonary artery pressure and diameter were measured in 9 anesthetized sheep. Pulmonary artery hypertension was induced by mechanical occlusion of the pulmonary artery and by phenylephrine infusion (5 mic...
