PURPOSE For the successful completion of transcatheter closure of atrial septal defects with the Amplatzer septal occluder, shape of the defects should be considered prior to selecting the device. The purpose of this study is to evaluate the results of a transcatheter closure of oval shaped atrial septal defect. MATERIALS AND METHODS From November 2009 until November 2011, cardiac computed to...

Two children (a 9 year old boy and a 2.5 year old girl) with coronary artery fistulae communicating with the right ventricle underwent successful transcatheter occlusion using an antegrade technique. A Rashkind double umbrella device was used in one case and an Amplatzer duct occluder in the other.

INTRODUCTION The device closure of atrial septal defects has evolved over the years. In the early days of transcatheter occlusion, balloon sizing was used to choose an appropriate sized device. We postulate that balloon sizing does not value-add to the procedure and is unnecessary. MATERIALS AND METHODS Patients who had balloon sizing, with (Group 1, n = 38) or without (Group 2, n = 21) atria...

INTRODUCTION Atrial septal defect (ASD) transcatheter occlusion techniques are now established as the preferred method and have become an alternative to surgery under extracorporeal circulation. In this study, we aimed to present our emergency surgical approach to cases of device embolization due to migration of the atrial septal defect occluder. MATERIAL AND METHODS Between June 2009 and Jun...

BACKGROUND Transcatheter closure of ostium secundum atrial septum defect (ASDII) using the new self-centering occluder, Amplatzer Septal Occluder (ASO), has been well developed in recent years. We describe the importance and role of transesophageal echocardiography (TEE) in the selection and closure of such defects. METHODS Thirty patients referred for transcatheter closure of ASDII by ASO we...

Case: A 36 year-old woman without significant past medical history was admitted with left-sided hemiparesis. Imaging studies confirmed a right middle cerebral artery (MCA) stroke with normal carotid arteries. Transesophageal echocardiogram (TEE) showed right heart enlargement and a large secundum atrial septal defect (ASD) (Figure 1). Using TEE guidance, an ASD occluder device was placed withou...

An atrial septal aneurysm may be associated with a patent foramen ovale. When paradoxical emboli result, the shunt must be closed and the atrial septal aneurysm excised. A reversed buttoned occluder device was successfully used for the transcatheter treatment of this condition.

A 10-year-old girl with symptoms of atypical infection and diagnosed disintegration of the occluder (Fig. 1) was referred for surgery. Intra-operatively the device was incorporated with atrial septum, but its surface was not completely endothelialized. All parts were removed (Fig. 2). The defect was closed with pericardial patch. www.elsevier.com/locate/ejcts European Journal of Cardio-thoracic...

Paravalvular leaks (PVLs) are a well-recognized complication of prosthetic valve replacement. Perivalvular prosthetic regurgitation causes significant morbidity and is associated with high perioperative mortality if open surgical repair is required. PVLs manifest with symptoms of congestive heart failure, hemolysis, or in most cases, the combination of both. In recent years, the development of ...
