Feasibility, safety, and effectiveness of transcatheter occlusion of atrial septal defect (ASD) with the buttoned device has been demonstrated. Despite its effectiveness in occluding secundum ASD with left-to-right shunt and patent foramina ovalia, presumably responsible for paradoxic embolism, it has limitations in effectively occluding ASD with evident(More)
Since the initial design and description of the buttoned device, it has undergone a number of design changes. Introduction of radiopacity in the knot (button) made it easier to visualize and document that buttoning has indeed occurred. Introduction of two buttons has markedly decreased the unbuttoning rate with potential for eliminating it. A centering(More)
A clinical trial was conducted of the buttoned device for transcatheter closure of ostium secundum atrial septal defect. Occlusion was attempted in 57 patients aged 1 to 62 years (median 5). The procedure was abandoned in 7 patients after 1 or more unsuccessful attempts, and devices were released in 50 patients. Urgent surgical retrieval was necessary in 4(More)
Several devices are available for transcatheter occlusion of atrial septal defect. This report describes the international experience with the buttoned device. During a 4.5-year period ending in February 1993, 180 transcatheter atrial septal defect occlusions were performed with the buttoned device. Patient age varied between 0.6 and 76 years and stretched(More)
BACKGROUND Several devices are available for transcatheter occlusion of patent ductus arteriosus. Most of these devices either require complicated intracardiac maneuvering, have not been tried in humans, or need a large-sized sheath for implantation of the device. METHODS AND RESULTS During a 26-month period ending November 1992, 14 patients underwent(More)
OBJECTIVES The purpose of this presentation is to document results of buttoned device (BD) occlusion of patent ductus arteriosus (PDA) in a large number of patients with particular emphasis on long-term follow-up in an attempt to provide evidence for feasibility, safety and effectiveness of this method of PDA closure. BACKGROUND Immediate and short-term(More)
OBJECTIVES This study was conducted to evaluate the intermediate-term results of the multi-institutional U.S. trial of the buttoned device for transcatheter closure of atrial septal defects (ASDs). BACKGROUND The trial was conducted in three centers (University of Arizona, University of Michigan and University of Wisconsin) under a Food and Drug(More)
UNLABELLED The transcatheter patch device consists of the following components: a sleeve type polyurethane patch, a double balloon support catheter and a retrieval thread. It has been applied in a variety of heart defects, including various types of atrial septal defects, ventricular septal defects and patent ductus arteriosus. New advances include an(More)
