mitochondria play an important role in energy production for the cell. the proper function of a myocardial cell largely depends on the functional capacity of the mitochondria.  therefore it is necessary to establish a novel and reliable method for a non-invasive assessment of mitochondrial function and metabolism in humans. although originally designed for evaluating myocardial perfusion, 99mtc...

abstract hypoplastic right ventricular is a rare congenital heart disease. a few cases have been reported. we presented a case with hypoplastic right ventricular and multiple associated anomaly (ventricular septal defect, atrial septal defect and pulmonary stenosis) in whom the main concern was whether biventricular repair or fontan type surgery would be the optimal management in this patient. ...

background: venoarterial extracorporeal membrane oxygenation (ecmo) provides systemic arterial support without directly unloading the left heart, which causes an elevated left ventricular (lv) pressure. the aim of the present study was to investigate the adjunctive application of the impella device for lv unloading in patients during ecmo. methods: this retrospective cohort study included patie...

background : prosthetic valve endocarditis (pve) is an important cause of morbidity and mortality associated with heart valve replacement surgery. the aim of the present study was to describe the early outcome of treatment in patients with pve in a single center. methods : the data of all the episodes of pve registered at our institution between 2002 and 2007 were collected and analyzed retrosp...

a total of 14 cases of infective endocarditis (ie) in children aged 6 months to 10 years were seen from december 1987 to december 1992 at the pediatric unit of ayatollah taleghani medical center. the majority of patients (12 of 14) were between 5 and 10 years of age. acyanotic congenital heart disease was known to preexist in 78.6% and rheumatic valvular heart disease in 21.4% of cases. organis...

acute left atrial thrombosis at the site of the resection of the primary cribriform septum is an exceedingly rare and important complication after atrial septal defect (asd) closure with a pericardial or synthetic patch. this case report presents a mobile thrombus noted on the left atrium at the raw surface site of a resected cribriform primary septum that was not caught in the suture line with...

1024x768 normal 0 false false false en-us x-none fa background : heart failure is a common health problem with poor prognosis. the gold standard for diagnosis is echocardiography but it is not always reachable, especially in emergency conditions. nt-pro-brain natriuretic peptide (nt-probnp) is a novel indicator for the diagnosis of heart failure and is being used in routine tests in emergency r...

background and objective: sleep-disordered breathing (sdb) is associated with increased morbidity and mortality in patients with heart failure (hf). we assessed the prevalence and the pattern of sdb in hf patients who were candidates for heart transplantation. materials and methods: twenty heart transplantation patients with ventricular ejection-fraction < 25% were recruited consecutively in a ...

Background Heart failure (HF) in infants and children with congenital heart disease (CHD) is a crucial complication with different outcomes. Many biomarkers are used as prognostic indicators. Soluble ST2 (sST2) is one of these markers studied in adults with HF. We aimed to study the prognostic value of sST2 in CHD children with HF. Materials and Methods In current case-control study, thirty-six...

the present study aimed to assess changes in resting and maximum heart rates as primary indicators of cardiac autonomic function in metabolic syndrome (mets) patients and to determine their value for discriminating mets from non-mets. 468 participants were enrolled in this cross-sectional study and assessed according to the updated adult treatment panel iii (atp-iii) definition of mets. resting...
