PURPOSE Transcatheter closure has become an effective therapy in most patients with patent ductus arteriosus (PDA). However, there are difficulties in transcatheter closure of PDA in small children. We reviewed clinical outcomes of transcatheter closure of PDA in children weighing less than 10 kg in a single center. METHODS Between January 2003 and December 2009, 314 patients with PDA underwe...
Transcatheter mitral interventions has been developed to address an unmet clinical need and may be an alternative therapeutic option to surgery with the intent to provide symptomatic and prognostic benefit. Beyond MitraClip therapy, alternative repair technologies are being developed to expand the transcatheter intervention armamentarium. Recently, the feasibility of transcatheter mitral valve ...
Current status and clinical development of transcatheter approaches for severe mitral regurgitation.
Transcatheter mitral valve intervention has emerged as an effective treatment option for symptomatic severe mitral regurgitation in patients considered to be inoperable or at high operative risk for surgical mitral valve surgery. Most transcatheter approaches are modifications of existing surgical approaches. Transcatheter edge-to-edge mitral valve repair with the MitraClip system has the large...
The Melody® transcatheter pulmonary valve (TPV) is a percutaneous valve system designed for the treatment of obstruction and/or regurgitation of prosthetic conduits placed between the right ventricle and pulmonary arteries in patients with congenital heart disease. In 2000, Melody TPV became the first transcatheter valve implanted in a human; in 2006 it became the first transcatheter valve comm...
Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...
BACKGROUND Studies on intracardiac echocardiography for transcatheter closure of secundum atrial septal defect (ASD) only include ASDs ≤38mm diameter without rim deficiency. AIMS To assess transcatheter closure of complex ASDs under intracardiac echocardiography guidance. METHODS Retrospective study from January 2006 to January 2012 in all consecutive adult patients referred to our centre f...
OBJECTIVE The aim of the current study was to evaluate the early experience of the application of transcatheter aortic valve implantation with the balloon-expandable system in China. The transcatheter aortic valve implantation technology has been widely used for patients with inoperable severe aortic stenosis in the developed world. The application of transcatheter aortic valve implantation is ...
OBJECTIVES We report our 8-year experience in transcatheter aortic and mitral valve-in-valve (VinV) implantation. BACKGROUND Feasibility and good early outcomes associated with transcatheter aortic and mitral VinV implantation into failed surgical bioprostheses have been confirmed, but the mid-term and long-term outcomes of transcatheter aortic and mitral VinV is unknown. METHODS A total of...
BACKGROUND Patent ductus arteriosus (PDA) is one of the most common congenital heart diseases and began to get treated by transcatheter occlusion since 1997 in China. Since then, several devices have been invented for occluding PDA. This study aimed to evaluate the technical feasibility, safety, and efficacy of transcatheter occlusion of PDA with different devices. METHODS One thousand five h...
BACKGROUND Transcatheter closure of congenital coronary artery fistulas (CCAFs) is an alternative therapy to surgery; however, data regarding transcatheter closure for CCAF with a giant coronary artery aneurysm (CAA) in pediatric patients are still limited due to the rarity of the disease. We aimed to evaluate the efficacy and safety of transcatheter closure for CCAF with a giant CAA in a pedia...
