right ventricular failure due to right coronary artery disease, right ventricular hypertrophy, stunning, abnormal septal motion, myocardial infarction, or non-homogeneous distribution of cardioplegia is an uncommon but serious complication of open heart surgery. we report a patient with severe right ventricular hypertrophy secondary to severe mitral valve stenosis and another patient with detac...

background : the signal-averaged electrocardiography is a noninvasive method to evaluate the presence of the potentials generated by tissues activated later than their usual timing in the cardiac cycle. the purpose of this study was to demonstrate the correlation between the filtered qrs duration obtained via the signal-averaged electrocardiography and left ventricular dimensions and volumes an...

introduction:  in patients who underwent surgery to repair tetralogy of fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. the aim of present study was to assess the effects of pulmonary valve replacement on rig...

background the early repolarization pattern (erp) has been considered a normal variant in electrocardiography (ecg) for a long time. nevertheless, increasing evidence has demonstrated its association with adverse outcomes. objectives the present study aimed to evaluate the prevalence of erp in the iranian general population and demonstrate its clinical and ecg correlates. methods a cross sectio...

noncompaction of the ventricular myocardium is an embryonic cardiomyopathy that is increasingly being recognized. noncompaction of lv myocardium, right ventricular myocardium, or both can occur in isolation, in congenital heart diseases, in valvular heart diseases, in neuromuscular disorders, skeletal abnormalities and in endocrinologic abnormalities. clinical manifestations of ventricular non-...

conclusion the cv value correlated more closely with low lvef and more accurately indicated an enlarged heart than ca or ctr. this may be due to the fact that an anteroposterior measurement of heart size is included in the former but not the latter two measurements. these study results may help quantify left heart enlargement with greater accuracy than may be obtained from standard cxr. backgro...

background: early clinical investigations indicate that an infusion of autologous bone-marrow cells into the infarct-related coronary artery is feasible after acute myocardial infarction. there is increasing evidence that cell transplantation may improve the perfusion and contractile function of the ischemic myocardium . the present study reports primarily the safety of intracoronary bone marro...

introduction: cardiac complications, including heart failure, are the most important secondary ones of the thalassemia major disease, which manifests itself in adolescence and early adulthood. appropriate, low cost diagnostic tools available as well as knowing its related factors are the most important components of therapy in these patients, given the importance of these complications, or by e...
