We have assessed right and left ventricular function by multigated radionuclide ventriculography in 12 consecutive patients with acquired immunodeficiency syndrome (AIDS) grouped according to the CDC classification system for HIV infection. Results were correlated with clinical, electrocardiographic and echocardiographic findings. Clinical examination and chest x-ray films showed no evidence of...

BACKGROUND The aim of this study was to assess the effect of left ventricular dysfunction on right ventricular ejection fraction during exercise in heart failure patients and its implications in functional capacity and blood pressure response. METHODS In a cross-sectional study 65 patients with heart failure were included. Left and right ventricular ejection fractions were evaluated by radio-...

background: assessment of myocardial function is essential in heart disease, but in regard to systolic and diastolic functions such evaluation has limitation. ejection fraction is difficult to assess in abnormally-shaped ventricles, and diastolic inflow velocity pattern may be fused because of tachycardia.   objective: a myocardial performance index (mpi) or tei index has been developed for adu...

Right and left heart volumes, ejection fractions and ventricular outputs were determined from biplane cineangiocardiograms in infants with symptomatic coarctation of the aorta and correlated with clinical and hemodynamic alterations. Patients were divided into two age groups: group 1, aged 3.5 to 14 days and group 2, 5 weeks to 7 1/2 months. Infants in group 1 had severe depressions of left ven...

Abstract Background Myocardial iron overload is the leading cause of death in patients with beta-thalassemia major. Combined therapy with deferiprone(DFP) and desferrioxamine (DFO)were suggested to be more effective than deferasirox(DFX) for removing heart iron. Deferasirox has recently been made available, but its long-term efficacy on cardiac function has not yet been established. Our study...

OBJECTIVE To establish the incidence of systolic and diastolic dysfunction of the right and left ventricle in a large cohort of patients after Mustard or Senning operations and to assess changes in the incidence on long term follow up. DESIGN Postoperative case-control study using radionuclide ventriculography. Ejection fractions, peak filling rates, rapid filling periods and fractions, slow ...

In order to assess left ventricular function in patients with rheumatic mitral stenosis, left ventricular function curves (plotting stroke work index vs left ventricular end-diastolic pressure) were constructed using angiotensin to augment, and nitroprusside to reduce, afterload. Hemodynamic responses to these alterations in afterload were measured. Resting ejection fractions and qualitative as...

PURPOSE To evaluate transthoracic minimally invasive device closure of atrial septal defects by performing transthoracic echocardiography to measure changes in cardiac hemodynamics and loading conditions. METHODS Between January 2012 and December 2012, we performed transthoracic minimally invasive device closure of atrial septal defects in 95 patients with secundum atrial septal defects (ASD)...

A selected group of 18 patients aged 15-27 years with transposition of the great arteries and a previous Mustard procedure were evaluated to determine their functional ability and clinical state. Arrhythmias were common, occurring at some time in 16/18 (89%). Arrhythmia was serious in four; two of them required pacing and two had cardiac arrests, one resulting in death. Seven (41%) had right ve...
