Transcatheter valve implantation is a novel interventional technique, which was developed as an alternative therapy for surgical aortic valve replacement in inoperable patients with severe aortic stenosis. Despite limited experience in using transcatheter valve implantation for mitral and aortic regurgitation, transapical transcatheter aortic valve implantation and valve-in-valve implantation ...
a secundum atrial septal defect is the most common congenital heart defect. transcatheter treatment of secundum atrial septal defects is a popular and less invasive alternative to surgery. procedural complications may occur in a wide spectrum, particularly device embolus as the most emergent one, but luckily they do not commonly occur in the clinical setting. mortality from adverse events relat...
Rupture of the interventricular septum is an uncommon but often fatal complication of acute myocardial infarction. Transcatheter closure is an established method of treating selected congenital defects but clinical experience on transcatheter closure of postinfarction ventricular septal defects (VSDs) is minimal. We report a case of successful transcatheter closure of postinfarction VSD using t...
BACKGROUND The use of transcatheter aortic-valve replacement has been shown to reduce mortality among high-risk patients with aortic stenosis who are not candidates for surgical replacement. However, the two procedures have not been compared in a randomized trial involving high-risk patients who are still candidates for surgical replacement. METHODS At 25 centers, we randomly assigned 699 hig...
Transcatheter aortic valves have been designed to treat elderly patients considered high-risk surgical candidates. Transcatheter aortic valve embolization represents a new complication previously unreported in the surgical bioprosthetic valve literature. We report the case of a 79-year-old male who successfully underwent aortic valve replacement after transcatheter aortic valve dislodgment into...
Patients with symptomatic aortic stenosis have a poor prognosis, and medical therapy has little, if any, effect on their natural history. Surgical aortic valve replacement (AVR) is risky, yet it appears to be effective in extending life expectancy and reducing symptoms due to aortic stenosis. In this setting, the development of transcatheter AVR appears to be a breakthrough technology, potentia...
OBJECTIVES The goal of this study was to compare survival between transcatheter mitral valve (MV) repair using MitraClip system (Abbott Vascular, Santa Clara, California), MV-surgery, and conservative treatment in high-surgical-risk patients symptomatic with severe mitral valve regurgitation (MR). BACKGROUND Up to 50% of patients with symptomatic severe MR are denied for surgery due to high p...
Transcatheter aortic valve implantation was developed to offer a therapeutic solution to patients with severe symptomatic aortic stenosis who are not candidates for conventional aortic valve replacement. The improvement in transcatheter aortic valve implantation outcomes is still of concern in the areas of stroke, vascular injury, heart block, paravalvular regurgitation and valve durability. Co...
BACKGROUND Right bundle branch block is an established predictor for new conduction disturbances and need for a permanent pacemaker (PPM) after transcatheter aortic valve replacement. The aim of the study was to evaluate the absolute rates of transcatheter aortic valve replacement related PPM implantations in patients with pre-existent right bundle branch block and categorize for different tran...
OBJECTIVES The purpose of this study was to determine whether a transcatheter procedure or surgical closure offers a better value proposition for atrial septal defect (ASD) closure. BACKGROUND Secundum ASDs are common congenital heart defects with both transcatheter and surgical treatment options. Although both options have been shown to have excellent results in children, the relative value ...
