although systolic dysfunction is revealed as a prognostic factor in cardiac surgery , the role of diastolic dysfunction as a predictive factor is less evaluated. in this retrospective study from 872 patients that underwent isolated coronary artery bypass graft(jan 2008-feb 2009),388 patients had normal left ventricular ejection fraction (>50%). these are divided in two groups, group 1: 361 pati...

BACKGROUND Surgical ventricular reconstruction is a specific procedure designed to reduce left ventricular volume in patients with heart failure caused by coronary artery disease. We conducted a trial to address the question of whether surgical ventricular reconstruction added to coronary-artery bypass grafting (CABG) would decrease the rate of death or hospitalization for cardiac causes, as co...

introduction: cardiovascular abnormalities have been reported in liver cirrhosis (lc). in these patients, cardiac symptoms and physical signs occur as the liver functions worsen. cirrhosis is associated with hyper dynamic circulation and beta-adrenergic system changes responsible for the cardiovascular abnormalities. the purpose of the present study was to explore the echocardiographic findings...

introduction patients with palliated congenital heart disease may present later in life for major, non-cardiac surgical procedures. although alternative surgical techniques are now available for the treatment of the transposition of the great arteries (tga), an atrial level baffle (mustard or senning procedure) was previously performed. long-term adverse effects of the atrial level switch inclu...

BACKGROUND Most patients with repaired tetralogy of Fallot require pulmonary valve replacement (PVR), but the evaluation for and management of ventricular arrhythmia remain unclear. This study is aimed at clarifying the optimal approach to this potentially life-threatening issue at the time of PVR. METHODS AND RESULTS A retrospective analysis was performed on 205 patients with repaired tetral...

Cardiac electrophysiological dysfunction is a major cause of death in humans. Accordingly, electrophysiological testing is routinely performed in intact, conscious, humans to evaluate arrhythmias and disorders of cardiac conduction. However, to date, in vivo electrophysiological studies in mice are limited to anesthetized open-chest or closed-chest preparations. However, cardiac electrophysiolo...

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...

background: the aim of this study was to investigate the correlation between the cardiac and hepatic iron-overload as assessed by magnetic resonance imaging t2 star (mrit 2 -star) technique and serum ferritin level in patients with thalassemia major. methods: in this cross-sectional study we evaluated 170 patients in sayed shohada hospital in isfahan in the year of 2009, cardiac and hepatic iro...
