The roles of posterior bulging of the interventricular septum (septal bulge) and of systolic septal mitral apposition in patients with simple transposition of the great arteries are not known. Cross sectional echocardiograms of 40 such patients were reviewed (after exclusion of those with fixed left ventricular outflow tract obstruction) and haemodynamic findings were compared with long and sho...

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 Identification of intramural basal-septal ventricular tachycardia (VT) substrate is challenging in nonischemic cardiomyopathy. We sought to (1) characterize normal/abnormal trans-septal right ventricular (RV) to left ventricular activation; (2) assess the effect of opposite RV pacing on left ventricular septal bipolar electrograms (EGMs); and (3) establish criteria for the identifica...

BACKGROUND Response to cardiac resynchronization therapy depends both on dyssynchrony and (regional) contractility. We hypothesized that septal deformation can be used to infer integrated information on dyssynchrony and regional contractility, and thereby predict cardiac resynchronization therapy response. METHODS AND RESULTS In 132 cardiac resynchronization therapy candidates with left bundl...

OBJECTIVE To examine how fetal and infant growth are related to left ventricular mass in adult life. DESIGN A follow up study of men born during 1920-30 whose birth weights and weights at 1 year were recorded. SETTING Hertfordshire, England. SUBJECTS 290 men born and still living in East Hertfordshire, England. MAIN OUTCOME MEASURE Left ventricular mass calculated from measurements of i...

RECENTLY Watkins and Gross' described a clinical syndrome that followed surgical closure of atrial septal defects in some of their patients. This syndrome consisted of the retention of fluid and a gain in weight during the early postoperative period. At times there followed tenderness in the right upper quadrant of the abdomen, hepatomegaly, and roentgenographic evidence of pulmonary congestion...

BACKGROUND/AIMS To investigate the role of endothelial dysfunction on left ventricular remodeling in patients with chronic kidney disease and to evaluate the correlation between endothelial dysfunction and left ventricular remodeling. METHODS Seventy-three patients with chronic kidney disease as study-group and thirty healthy volunteers as control-group were enrolled in the present study. All...

Percutaneous alcohol ablation of the interventricular septum via the first septal perforator branch of the left anterior descending artery can successfully treat dynamic left ventricular outflow tract obstruction in patients with hypertrophic cardiomyopathy. Increasingly, echocardiographic contrast agents are used before alcohol injection to identify the perfusion bed of the septal perforator v...

wall thickness of 14 mm as stated in the caption of Figure 2. The incidence of intraventicular septal thickness of more than 13 mm (14 to 16 mm) was 11% (17 of 156 subjects) as stated in the Results section. The incidence of either the intraventricular septal wall or left ventricular free wall being more than 13 mm was actually higher (13%; 20 of 156 subjects). The findings presented in our stu...
