background: there is some evidence indicating improvement in myocardial performance after atrial septal defect closure, either device closure or surgical, but ventricular dyssynchrony has not been evaluated before and after surgical closure. the aim of this study was to evaluate ventricular mechanical dyssynchrony in patients with atrial septal defect before and after surgical closure. methods:...

propafenone hci (p), is a relatively new class ic antiarrhythmic agent. it has been reported to be superior to conventional antiarrhythmics in the control of supraventricular, ventricular and wpw associated tachyarrhythmias. it has been also shown to be well tolerated. in our study protocol, which extends over 2~ years period , we used (p) in 87 patients for management of various types of cardi...

performance of heart has substantial role in breaking records of sports. achieving to optimal performance of endurance training builds upon the consistency in several parts of body specially heart. type, intensity, term training programs is determining components of providing structural consistency and performance of heart especially in left ventricular. aim of this research was comparing struc...

takotsubo cardiomypathy is a very rare cardiovascular syndrome leading to myocardial infarction and left ventricular dysfunction in the absence of a detectable coronary artery lesion. it is accepted as reversible left ventricular asynergy occuring typically after an intrinsic adrenergic hyperstimulation. in this report we present takotsubo cardiomyopathy in a 75-year-old patient with multiple a...

backgroundasthma is the most chronic inflammatory disorder of the airways in children and asthmatic patients can experience cardiac dysfunction, pulmonary hypertension and finally cor pulmonale later in life. we aimed to investigate right ventricular (rv) functions in asthmatic children by conventional and tissue doppler echocardiography (tde).materials and methods pulmonary function tests, con...

background: closure of patent ductus arteriosus (pda), ventricular septal defect (vsd) and atrial septal defect (asd) can be done surgically or by device. this study was designed to compare the total cost of surgical or device closures of pda, asd or vsd for iranian patients. methods: this is a cross-sectional study, conducted from january 1, 2005 until january 1, 2006 in two large heart center...

today, congenital heart diseases may be treated without surgery through advances in interventional cardiology. however, complications such as infection and thrombus formation may develop due to foreign materials used during these procedures. surgical intervention may be required for the removal of the device utilized for the procedure. in this case report, we present the surgical treatment of a...

background: n-terminal pro-brain natriuretic peptide (nt-probnp) is a sensitive biomarker for the detection of asymptomatic left ventricular (lv) dysfunction. since β-thalassemia major patients suffer from early diastolic dysfunction due to iron deposition of chronic blood transfusion, we tried to evaluate the correlation between the serum nt-probnp level and the severity of lv diastolic dysfun...

Coronary arteriosystemic fistula which drains into the left ventricular cavity is a rare congenital anomaly. A case of double fistulae between the left anterior descending and left circumflex coronary arteries and left ventricular cavity is presented. The patient's chief complaint, chest pain, was attributable to the "steal phenomenon."

background: the cardiac effects simultaneously occurring during experimental hypertension and diabetes have rarely been investigated. this study aimed at examining the effects of short-term renovascular hypertension and type 2 diabetes on cardiac functions. methods: five groups (7 each) of male sprague-dawley rats, including a control group, a diabetes (induced by streptozocin and nicotinamide)...
