Patent foramen ovale and atrial septal defects are common cardiac defects that can be routinely closed with transcatheter devices, rather than more invasive open surgical techniques. There is good evidence supporting both surgical and transcatheter closure of atrial septal defects, but there remains controversy regarding some of the currently applied indications for patent foramen ovale closure...

A 22-year-old male presented with recurrent stroke, central cyanosis, and dyspnea. Transesophageal echocardiography and cardiac catheterization revealed bidirectional shunt flow through atrial septal defect (ASD) without pulmonary arterial hypertension. The orifice of inferior vena cava facing towards ASD opening led partially right to left shunt resulting in cyanosis with normal pulmonary arte...

Percutaneous transcatheter closure of ruptured sinus of valsalva aneurysm was attempted in eight patients between January 1995 and March 2003 as an alternative strategy to surgery as this technique at present is an accepted therapeutic modality for various intracardiac defects. The age range was 14-35 years, all were male, seven in symptomatic class III and one in class IV on medical treatment....

Patients with an atrial septal defect (ASD) have a left to right shunt with associated complications. Currently, various imaging modalities, including echocardiography and invasive cardiac catheterization, are utilized in the management of these patients. Cardiac magnetic resonance (CMR) imaging provides a novel and non-invasive approach for imaging patients with ASDs. A study of vortices gener...

OBJECTIVES Transcatheter closure of a secundum atrial septal defect (ASD II) has become an effective alternative for surgical treatment. In this study we evaluated the correlation between the two-dimensional transoesophageal echocardiographic (2D TEE) sizing of ASDs and the actual diameter of occluders in patients undergoing device closure. METHODS The records of 54 patients who underwent tra...

OBJECTIVE To review the safety and efficacy of the Amplatzer septal occluder for transcatheter closure of interatrial communications (atrial septal defects (ASD), fenestrated Fontan (FF), patent foramen ovale (PFO)). DESIGN Prospective study following a common protocol for patient selection and technique of deployment in all participating centres. SETTING Multicentre study representing tota...

Atrial septal defect closure is now routinely performed using a percutaneous approach under echocardiographic guidance. Centrally located, secundum defects are ideal for device closure but there is considerable morphological variation in size and location of the defects. A small proportion of atrial septal defects may have multiple fenestrations and these are often considered unsuitable for dev...

ALTHOUGH atrial septal defect is onle of the commllonlest of the congenital heart lesions, and the anatomical features have been recognised since the early nineteenth century, it is only in the last thirty years that a clearly defined clinical picture has emerged (Roesler, 1934; Bedford Papp and Parkinson, 1941). Precision in diagnosis came with the use of cardiac catheterization (Wood, 1950; D...

A major advantage of echocardiography over other advanced imaging modalities (magnetic resonance imaging, computed tomographic angiography) is that echocardiography is mobile and real time. Echocardiograms can be recorded at the bedside, in the cardiac catheterization laboratory, in the cardiovascular intensive care unit, in the emergency room-indeed, any place that can accommodate a wheeled ca...
