Recent experience with the spring-loaded patent ductus arteriosus (PDA) occluder has demonstrated several advantages of this device in the closure of intracardiac defects compared with previously described techniques. Pathologic and animal model studies were performed to identify which atrial septal defects (ASDs) might be suitable for device closure and to test a new septal closure double umbr...
We have recently used the Amplatzer septal occluder to close Fontan fenestrations. Between June 1998 and December 1999, 13 patients underwent transcatheter occlusion of their Fontan fenestrations. Systemic blood flow decreased significantly without a concomitant decrease in pulmonary blood flow. All residual shunts detectable by oximetry were at sites separate from those into which occlusion de...
BACKGROUND Although currently used devices for interventional closure of patent foramen ovale (PFO) are widely used due to the minimally invasive nature of this technique and high success rate, there is still a need to look for new materials and designs in order to improve the treatment outcomes. AIM To evaluate the safety, biocompatibility, temporal healing patterns, and coverage dynamics of...
BACKGROUND Percutaneous closure of patent ductus arteriosus (PDA) has become standard therapy. Experience with the Occlutech® Duct Occluder is limited. METHODS Data regarding ductal closure using Occlutech® Duct Occluder were reviewed and prospectively collected. Demographics, hemodynamic and angiographic characteristics, complications, and outcomes were documented. RESULTS From March 2013 ...
INTRODUCTION The purpose of this study was to investigate the clinical value of real-time three-dimensional transesophageal echocardiography (RT-3D-TEE) for percutaneous transcatheter closure of multiple secundum atrial septal defects (ASDs) using a Chinese domestic occluder device. METHODS From July 2008 to September 2011, 37 patients (mean age 28.4 ± 9.7 years; 24 females) with multiple sec...
BACKGROUND Transcatheter closure of secundum type atrial septal defect (ASD) has become a standard procedure in most medical centers. Although the procedure is invasive and has a shorter recovery duration and a lower complication rate compared with surgery, it is not risk-free. In this retrospective chart review case series, we report our experience of management of complications after placemen...
