OBJECTIVE The aim of the study was to investigate the effect of intragastric balloon therapy on left ventricular function and left ventricular mass in a cohort of morbidly obese patients. SUBJECTS AND METHODS A prospective trial was performed in a cohort of 17 class II and class III morbidly obese individuals. The intragastric balloon was retained in the stomach for an average of 6 months. Co...

Background Recent studies suggest the ability of phase-contrast cardiovascular magnetic resonance (PC-CMR) to provide velocity and flow-related left ventricular diastolic function parameters in good agreement with Doppler echocardiography (DE). Furthermore, DE diastolic parameters are known to change with aging. The aim of the present study is to assess whether the age-related variations of dia...

Right ventricular function is frequently abnormal in patients with systemic sclerosis, but whether this is related to pulmonary vascular complications of the disease is unclear. Standard echocardiography with tissue Doppler imaging was performed at rest and during exercise for the study of right ventricular function and pulmonary circulation in 25 consecutive systemic sclerosis patients and in ...

BACKGROUND The aim of this study was to evaluate myocardial function in patients with non-hypertensive metabolic syndrome. METHODS We selected metabolic syndrome patients (n = 42) without evidence of hypertension and compared them to age-matched control individuals (n = 20). All patients were evaluated by two-dimensional and tissue Doppler echocardiography including tissue Doppler derived str...

background: iron-mediated cardiomyopathy is the main complication of thalassemia major (tm) patients. therefore, there is an important clinical need in the early diagnosis and risk stratification of patients. the aim of this study was to evaluate the efficacy of tissue doppler imaging (tdi) to study cardiac iron overload in patients with tm using t2* magnetic resonance (mr) as the gold-standard...

Introduction: We aimed to evaluate the relationship between coronary tortuosity and left ventricular relaxation disorder using conventional new diastolic function parameters evaluated with echocardiography. Methods: A total of 131 patients who underwent angiography for suspected artery disease were included in study. compared obtained echocardiography (CAT) normal arteries. Results: There was n...

BACKGROUND Tissue Doppler imaging is used routinely to quantify both left and right ventricular function. However, normal reference values of echocardiography parameters of the right ventricle in Iranian population are still unknown. OBJECTIVES Accordingly, we conducted a study to determine the normal values of echocardiography parameters of right ventricular function in a healthy Iranian pop...

BACKGROUND Previous studies indicate that compared with physical examination, Doppler echocardiography identifies a larger number of cases of rheumatic heart disease in apparently healthy individuals. OBJECTIVES To determine the prevalence of rheumatic heart disease among students in a public school of Belo Horizonte by clinical evaluation and Doppler echocardiography. METHODS This was a cr...
