OBJECTIVES This study sought to analyze the safety, efficacy, and follow-up results of percutaneous closure of secundum atrial septal defect (ASD) in young children. BACKGROUND Results of ASD transcatheter closure in adults are widely reported but there are no large published series concerning young children. METHODS Between December 1996 and February 2002, 48 of 553 patients percutaneously...

Background: Atrial septal defect (ASD) is the most common congenital heart disease (CHD) in adults after bicuspid aortic valve. Although the defect is often asymptomatic until adulthood, undetected ASDs could lead to potential irreversible complications like arrhythmias, stroke, pulmonary hypertension and its squeal. The purpose of our study was to determine the value of surgical closure of atr...

OBJECTIVES The goal of this study was to report the early and late complications experienced in atrial septal defect (ASD) transcatheter closure. BACKGROUND Atrial septal defect transcatheter occlusion techniques have become an alternative to surgical procedures. A number of different devices are available for transcatheter ASD closure. The type and rate of complications are different for dif...

OBJECTIVES This study sought to determine whether transthoracic echocardiography (TTE) can provide safety and efficacy equivalent to transesophageal echocardiography (TEE) for assessment and guidance of transcatheter atrial septal defect (ASD) closure in pediatric patients. METHODS We performed a prospective randomized trial of ASD closure using the Amplatzer septal occluder (ASO) from March ...

Hemodynamic and ventricular volume parameters were evaluated in 21 patients (24 studies) with total anomalous pulmonary venous return (TAPVR), 11 patients with secundum atrial septal defect (ASD), and eight patients who had complete correction of TAPVR or ASD. Right and left ventricular (RV and LV) volume parameters were calculated according to Simpson's rule and the area length methods, respec...

We report the management of a patient with secundum atrial septal defect (ASD) and severe pulmonary hypertension. A 65-year-old male with recently diagnosed atrial septal defect was referred to our centre for decompensated right heart failure with rest and exercise induced dispnea and severe pulmonary hypertension. Right heart catheterization confirmed a mean pulmonary pressure of about 55 mmHg...

The atrioventricular (A-V) conduction time in patients with secundum ASD who had left-toright shunts of 40-65% of their pulmonary flow was evaluated utilizing intracardiac electrograms. The A-V conduction time was divided into three components: (1) P-A interval, from the onset of the P wave to the time of excitation of muscle in the vicinity of the A-V node, (2) A-H interval, from the time of e...

OBJECTIVE The main purpose of present study was to investigate the impact of percutaneous closure of atrial septal defect (ASD) on right ventricular (RV) systolic function assessed by tricuspid annular isovolumic myocardial acceleration (IVA) that is independent of preload and afterload changes. METHODS A prospective cohort study was designed involving twenty five patients with secundum type ...

Excellent definition of anatomic structure, ability to provide detailed flow information, and a global field of view make magnetic resonance imaging (MRI) well suited as a tool for the noninvasive diagnosis of congenital heart disease. One of the most frequently encountered lesions is the atrial septa1 defect (ASD), which may be associated with important morbidity in the long term if unrecogniz...

BACKGROUND Concerns remain that minimally invasive atrial septal defect (ASD) repair may compromise patient outcomes. We compared clinical outcomes of adult patients undergoing ASD repair via a minimally invasive endoscopic approach versus a "gold standard" sternotomy. METHODS We retrospectively reviewed the clinical outcomes of consecutive patients who underwent ASD patch repair at our insti...
