conclusions the right ventricular outflow tract palliation in children with cyanotic chd leads to long-term favorable outcome regarding improvement in oxygen saturation, increase in z score of both left and right pulmonary arteries and also considerable decrease in spell. also, death and complications are rare following rvot palliation. background the right ventricular outflow tract (rvot) pall...

n-terminal pro β-type natriuretic peptide (nt-probnp) is a valuable marker for monitoring the response to treatment in patients with heart failure. based on the clinically observed improvement of heart failure symptoms early after cardiac resynchronization therapy (crt), we sought to investigate whether crt induce any significant reduction in the plasma level of nt-probnp in three days after im...

heart failure is common in patients with chronic renal disease, either as a complication of renal failure or from shared risk factors, or is the major cause of death in patients on dialysis. at present, end stage renal disease (esrd) patients who have systolic heart failure are considered high-risk for surgery; and nephrologists and cardiologists are reluctant to refer these patients for kidney...

infective endocarditis is an uncommon heart disease with a variable incidence, mostly related to the ever-increasing development of cardiac surgery and the longer survival of patients with congenital heart disease (chd). thirty-seven episodes of infective endocarditis (ie) were evaluated in 36 children (under 15 years of age) admitted to hospitals affiliated to shiraz university of medical scie...

primary leiomyosarcoma of the heart is extremely rare and found in about 0.2% of all cardiac tumors. here in a 26-year-old man with progressive dyspnea, which had started since 2 months ago, is presented. echocardiography revealed a left atrial mass, which was suggestive for a atrial myxoma.on the surgery, a tumoral tissue in the left atrium and pulmonary veins with attachment to peripheral sof...

a 5-year-old girl was admitted to the hospital with chest pain, fever and dyspnea. physical examination showed normal heart sounds, diminished pulmonary sounds in the left hemithorax and a normal ecg. on chest x-ray the heart was slightly enlarged with moderate left pleural effusion. ct scan revealed pleural effusion and a hypodense mass at the apex of the heart. a cystic mass was detected by e...

background: ischemic heart disease is the leading cause of death in most societies. in a pathophysiologic point of view, it chiefly results from the formation of thrombus in coronary arteries which could not be only prevented by aspirin. many of clinical trials have shown the long-term benefits of antiplatelet drugs in reducing the risk of thrombotic accidents. objectives: clopidogrel is a thie...

background: severe and prolonged physical training is associated with morphological and physiological cardiac changes, often termed as the “athlete’s heart”. echocardiographic features peculiar to elite iranian athletes have not been previously described. the aim was to examine the echocardiographic characteristics of highly trained iranian athletes involved in three different sports.   methods...

Cardiac diseases are common post-stroke and are associated with increased morbidity and mortality. One possible mechanism of acute cardiac injury is the neurogenic myocardial damage, where the cerebral injury is disturbing the normal sympathetic and parasympathetic neuronal outflow to the heart leading to cardiac damage including myocardial infarctions. The exact mechanism is not completely und...

background: this study was undertaken to compare the outcome in patients with moderate to severe ischemic mitral regurgitation (imr) undergoing coronary artery bypass grafting (cabg) with either mitral valve repair or mitral valve replacement. methods: between march 2002 and february 2005, 49 consecutive patients (mean age: 62.84±8.42 years; mean euroscore: 10.03±3.12) with coronary artery dise...
