A simple, noninvasive radionuclide technique which measures the severity of valvular regurgitation has been developed. The technique compares right and left ventricular stroke volume indices (change in counts between diastole and systole over the left and right ventricles) from 45 degrees LAO gated cardiac blood pool scans. In 14 control subjects, the left-to-right ventricular stroke index rati...

background: one of the most important heart diseases in dogs is valvular insufficiency, which can be evaluated by diagnosis ways such as phonocardiography, echocardiography, etc. objective: the purpose of the current study was to evaluate of valvular insufficiencies with phonocardiography and echocardiography and using phonocardiography technique in detection of cardiac valvular disease in prac...

Aortic regurgitation (AR) is characterized by diastolic reflux of blood from the aorta into the left ventricle (LV). Acute AR typically causes severe pulmonary edema and hypotension and is a surgical emergency. Chronic severe AR causes combined LV volume and pressure overload. It is accompanied by systolic hypertension and wide pulse pressure, which account for peripheral physical findings, suc...

Valvular diseases are a leading cause of morbidity, mortality and impaired quality life in all over the world with different epidemiology. It is extremely important to know hemodynamic changes for proper development strategy future interventions. The recent years shows progress various methodologies field surgery interventional treatments valvular diseases. In this section, we focus mainly on a...

OBJECTIVE To assess whether valvular lesions are associated with the use of dexfenfluramine in Chinese patients with type 2 diabetes. DESIGN Case-control study. PATIENTS AND METHODS Thirty-six obese Chinese patients with type 2 diabetes and a history of dexfenfluramine use during the period January 1992 and September 1997 were recruited into the study, while another 43 age- and sex-matched ...

Chronic venous disease (CVD) is a very common health problem concerning up to 1/3 of the society. Although venous hypertension and valvular incompetence have been long known to be crucial for development of the illness, its exact aetiology remains unclear. Recent findings indicate that inflammatory processes may be crucial for development of incompetent valves and vein wall remodelling. One of ...

Fenestrations of the aortic valve rarely produce significant valvular regurgitation. These are typically described as incidental findings with little clinical significance because they generally lie above their closing edges. Rarely however, when unusually large or multiple, they can lead to massive aortic regurgitation (AR), mostly in patients with chronic hypertension and/or aortic annular di...

Catastrophic antiphospholipid syndrome (CAPS) is a severe form of antiphospholipid syndrome (APS). It frequently leads to multiorgan failure with an approximate mortality rate of 50%. The heart is involved in about 50% of the patients with CAPS. We report two cases with CAPS and severe heart manifestations, documented by echocardiography. Both women show regression of the valvular regurgitation...

BACKGROUND Lhasa is the main residence of Tibetans and one of the highest cities in the world. Its unique geography and ethnic population provide the chance to investigate the interactions among high altitude, ethnicity, and cardiac adaptation. Meanwhile, echocardiographic data about healthy Tibetans on a large scale are not available. This study aimed to analyze physiological factors related t...
