In the first part of the study, the influence of changes in preload and afterload on mean circumferential fiber shortening velocity, Vcf, was investigated in the absence of any extrinsic cause for change in the contractile state of the left ventricle (LV) of seven dogs. In five of seven dogs in which afterload was controlled and contractility was unchanged, there was a significant negative corr...

background: heart disease is the main cause of mortality and morbidity in patients with beta thalassemia, rendering its early diagnosis vital. we studied and compared echocardiographic findings in patients with beta thalassemia major, patients with beta thalassemia intermedia, and a control group. methods: eighty asymptomatic patients with thalassemia major and 22 asymptomatic cases with thalas...

conclusions echocardiography and 2d speckle tracking strain imaging shows improvements in left ventricular deformation indices in atrioventricular reentrant tachycardia (avrt) and atrioventricular nodal reentrant tachycardia (avnrt) patients for the mean systolic strain and strain rate at 24 hours and the three-month follow-up. in spite of the normal lvef, even during sinus rhythm, deformation ...

background: there is some evidence indicating improvement in myocardial performance after atrial septal defect closure, either device closure or surgical, but ventricular dyssynchrony has not been evaluated before and after surgical closure. the aim of this study was to evaluate ventricular mechanical dyssynchrony in patients with atrial septal defect before and after surgical closure. methods:...

abstract: the preoperative and surgical management of a giant left ventricular pseudoaneurysm(lvp) associated with aortic valve replacement in a 76 year old male jehovah’s witness patient is reported. the satisfactory recovery observed in this patient demonstrates the feasibility of this complex surgical procedure even in this particular patient population.

conclusions the administration of curcumin in patients undergoing dialysis had no positive effects on enhancing lvef and lv function. further research is required to shed sufficient light on this issue. results the mean age was 44.2 ± 13.4 years for the curcumin group and 45.4 ± 6.2 years for the placebo group. the study population comprised 22 male and 13 female patients. there were no signifi...

background: ventriculoatrial (va) conduction has an important role in the initiation and maintenance of some arrhythmias. the aim of this study was to evaluate whether clinical and electrophysiological parameters of atrioventricular (av) conduction can predict va conduction. methods: detailed demographic, electrocardiographic, and echocardiographic data were recorded in 54 consecutive patients ...
