Reduced cavernosal arterial inflow has been hypothesized to be the likely cause of erectile dysfunction after kidney transplants in recipients revascularized through end-to-end anastomosis to the internal iliac artery, suggesting that end-to-side anastomosis at the external iliac artery is preferable. The aim of this study was to prospectively evaluate the effect of the use of the external ilia...

OBJECTIVE Diastolic function is frequently impaired in diabetic patients. Our aim was to evaluate the effects of glycometabolic control achieved by pancreas transplantation on left ventricular function in uremic type 1 diabetic patients. RESEARCH DESIGN AND METHODS Left ventricular systolic and diastolic functions were evaluated using radionuclide ventriculography in 42 kidney-pancreas transp...

The estimation of ventricular volumes by indicator dilution methods is subject to errors resulting from incomplete mixing and nonuniform sampling. A mathematical model is proposed which theoretically permits calculation of these errors. The model allows for nonuniform distribution of indicator in the ventricle and for nonuniform representation of the end-diastolic volume (EDV) in the systolic e...

This study aims to analyze the superior artery blood flow in healthy premature neonates with birth weight between 1,000 g and 1,500 g, on the first and seventh days of live. It is a prospective cohort study, including 15 premature neonates with mean weight of 1,243g ± 173.6 (ranging from 1,000 to 1,495 g). Exclusion criteria were: unstable hemodynamic conditions; assisted ventilation with high ...

Abstract Background Women with signs and symptoms of ischemia no obstructive coronary arteries (INOCA) have evidence diastolic dysfunction are at increased risk developing heart failure preserved ejection fraction (HFpEF). However, mechanisms contributing to HFpEF development poorly understood often attributed underlying cardiovascular factors. Purpose To compare clinical, invasive, imaging par...

patients and methods twenty-two young men (age = 23.34 ± 2.56 years, weight = 72.47 ± 12.01 kg, and height = 174.10 ± 5.75 cm) were recruited and randomly assigned into control (n = 10) and hiit (n = 12) groups. echocardiography was used to evaluate left ventricular mass (lvm), end-systolic volume (esv), end-diastolic volume (edv), interventricular septal wall thickness (ivswt), stroke volume, ...

AIMS Right ventricular (RV) mass and volume calculations are important correlates of survival in patients with pulmonary arterial hypertension (PAH). We tested the hypothesis that RV mass, volumes and function could be measured accurately with real-time three-dimensional echocardiography (3DE) in patients with PAH and compared those against cardiac magnetic resonance (CMR). METHODS AND RESULT...

Blood flow in the pulmonary artery was studied by Doppler colour flow mapping and cardiac catheterisation in 19 patients with a ductus arteriosus and different pulmonary artery pressures. In the four patients with normal pulmonary artery pressures colour Doppler flow mapping showed multicoloured wide and long systolic and diastolic jets in the pulmonary artery. In the 15 patients with raised pu...

  Introduction: Although left ventricular(LV) function parameters measured by gated myocardial perfusion SPECT (GSPECT) have been validated, experimental data have revealed that the calculated the LV function parameters using GSPECT are affected by patient populations as well as particular acquisition and processing conditions. We tried to determine the normal values ...
