OBJECTIVE To determine the feasibility and effectiveness of endoscopic atrial septal defect (ASD) closure when percutaneous ASD closure is impossible or has failed. PATIENTS Between March 1997 and February 2003, 74 patients (63% female, mean (SD) age 44 (16) years) underwent an endoscopic ASD closure. Median preoperative New York Heart Association functional class was I. Clinical and echocard...

A 68 year old woman presented with right ventricular myocardial infarction complicated by refractory hypoxaemia. She was found to have a significant right to left shunt at the atrial level through a previously undiagnosed ostium secundum atrial septal defect. Percutaneous closure of the atrial septal defect with an Amplatzer septal occluder resulted in prompt improvement in her oxygenation and ...

Objective: To determine the feasibility and effectiveness of endoscopic atrial septal defect (ASD) closure when percutaneous ASD closure is impossible or has failed.

venous injections ofdextrose 5 per cent in water, for the detection and localisation of atrial and ventricular right-to-left shunts was evaluated in 70 adult patients. Based on their catheterisation data, 20 patients had a shunt at atrial level (group 1) and 14 patients a ventricular septal defect (group 2). Thirty-six patients without a shunt by oximetry served as controls. Echo contrast could...

A 23-year-old male referred for evaluation of a "choking" sensation with exertion and a murmur. A transthoracic echocardiogram demonstrated right atrial and ventricular dilatation, right ventricular volume overload, and a large secundum atrial septal defect (ASD) with left to right shunt and a calculated pulmonary-to-systemic blood flow ratio (Qp/Qs) estimated at 2.3 to 1. Cardiac catheterizati...

Objective: To investigate the natural history of secundum atrial septal defects (ASDs) over several years using serial echocardiographic studies. Methods: All patients with isolated secundum ASDs who had serial transthoracic echocardiograms at Texas Children’s Hospital, Houston, Texas, from January 1991 to December 1998 were identified. Patients with fenestrated or multiple ASDs, other congenit...

INTRODUCTION Anterior mini-thoracotomy approach is a good alternative to median sternotomy in Atrial Septal Defect (ASD) repair. Our purpose is to explain the details of our technique and peresent the results. METHODS Seventy five patients with ASD (52 female and 23 male) were operated with anterior mini-thoracotomy approach in our tertiary center between March 2012 and March 2014. The mean a...

The purpose of this review is to discuss the management of atrial septal defects (ASD), paying particular attention to the most recent developments. There are four types of ASDs: ostium secundum, ostium primum, sinus venosus, and coronary sinus defects. The fifth type, patent foramen ovale-which is present in 25 to 30% of normal individuals and considered a normal variant, although it may be th...

A 67-year-old male patient with an eight-month history of operation for mitral valve repair and secundum atrial septal defect (ASD) presented with complaints of fatigue and shortness of breath. Transthoracic echocardiography showed a residual ASD resulting from separation of a pericardial patch. Qp/Qs rate was 3.2. The diameter of the residual defect measured by transesophageal echocardiography...

Objective: To assess the short-term outcome following transcatheter closure of secundum atrial septal defect (ASD) in our hospital. Patients and Methods: Between June 2000 and November 2001, 20 patients diagnosed as secundum atrial septal defects underwent transcatheter closure of their defects using the Amplatzer septal occluder (ASO) device. Indications for 18 patients were larger atrial sept...
