background: there are some conflicting results with conventional coronary artery bypass grafts (ccabg) with arrested heart in coronary high-risk patients. moreover, performing off-pump cabg in these cases may be associated with serious complications. the objective of this study is to evaluate the efficacy of the on-pump beating cabg (opbcabg) in coronary high-risk patients in comparison with th...

Normal or near-normal exercise capacity has been thought to reflect normal left ventricular function. Many compensatory mechanisms could preserve exercise capacity in patients with severe left ventricular dysfunction. We evaluated exercise capacity using a treadmill exercise test in 26 patients with severe left ventricular dysfunction defined by a left ventricular ejection fraction of 30% or le...

BACKGROUND/AIMS To investigate the role of endothelial dysfunction on left ventricular remodeling in patients with chronic kidney disease and to evaluate the correlation between endothelial dysfunction and left ventricular remodeling. METHODS Seventy-three patients with chronic kidney disease as study-group and thirty healthy volunteers as control-group were enrolled in the present study. All...

A 16-year-old female with ventricular dysfunction and frequent ventricular arrhythmia presented with a cardioembolic stroke. Prior electrophysiology study and ablation was performed for ventricular tachycardia (VT). For remaining ventricular ectopy, the patient was maintained on carvedilol and mexiletine. After one year on this regimen, she presented with an acute stroke. Transesophageal echoca...

BACKGROUND All 3 palliation strategies, Norwood, Sano, and Hybrid, currently used for hypoplastic left heart syndrome pose a risk of myocardial injury at different times and through different mechanisms. We sought to compare these strategies to understand longitudinal differences in interstage ventricular dysfunction and their subsequent impact on transplant-free survival and atrioventricular v...

Left ventricular function was assessed in 14 patients with chronic aortic regurgitation by afterload elevation with angiotensin. Seven of 14 patients maintained their resting ejection fraction with angiotensin (group A), while the remaining seven experienced a decline of greater than 0.10 in ejection fraction (group B). Six of seven group A patients showed an appropriate rise in left ventricula...

BACKGROUND Plasma concentration of B-type natriuretic peptide (BNP) has been suggested as a powerful screening tool for left ventricular systolic dysfunction. However, there are reports indicating that the 12-lead electrocardiogram (ECG) could be just as powerful. We aimed to evaluate the 12-lead ECG and BNP as screening tools for left ventricular systolic dysfunction in an elderly, unselected ...

Background:Multisystem inflammatory syndrome in children (MIS-C) is a rare temporally related to severe acute respiratory coronavirus 2 (SARS-CoV-2). MIS-C shares similarities with Kawasaki disease, but left ventricular dysfunction more common MIS-C.

BACKGROUND Echocardiographically assessed right ventricular dysfunction is increasingly used to guide more aggressive therapy in hemodynamically stable patients with acute pulmonary embolism (PE). However, the prognostic value of right ventricular dysfunction in these patients is still unclear. METHODS We systemically reviewed the literature to assess the prevalence of echocardiographic right...

INTRODUCTION The aim of this study was to assess the prevalence, determinants and correlates of right ventricular (RV) systolic and diastolic dysfunction (RVSD and RVDD, respectively) in hypertensives, stratified by left ventricular (LV) geometric patterns. METHODS The study was carried out in Aminu Kano Teaching Hospital in Kano, Nigeria, and was cross-sectional in design. Hypertensive subje...
