Journal ArticleDOI
Short- and Medium-Term Outcomes After Transcatheter Pulmonary Valve Placement in the Expanded Multicenter US Melody Valve Trial
Doff B. McElhinney,William E. Hellenbrand,Evan M. Zahn,Thomas K. Jones,John P. Cheatham,James E. Lock,Julie A. Vincent +6 more
TL;DR: In this updated report from the multicenter US Melody valve trial, an ongoing high rate of procedural success and encouraging short-term valve function is demonstrated, highlighting the importance of patient selection, adequate relief of obstruction, and measures to prevent and manage stent fracture.
Journal ArticleDOI
Erosion of Amplatzer septal occluder device after closure of secundum atrial septal defects: Review of registry of complications and recommendations to minimize future risk
Zahid Amin,Ziyad M. Hijazi,John L. Bass,John P. Cheatham,William E. Hellenbrand,Charles S. Kleinman +5 more
TL;DR: The risk of device erosion with ASO is low and complications can be decreased by identifying high‐risk patients and following them closely, as well as identifying high-risk cases, early recognition, and prompt intervention.
Journal ArticleDOI
Implantation of the Melody Transcatheter Pulmonary Valve in Patients With a Dysfunctional Right Ventricular Outflow Tract Conduit Early Results From the U.S. Clinical Trial
TL;DR: Implantation of the Melody valve for right ventricular outflow tract conduit dysfunction can be performed by experienced operators at multiple centers, appears safe, and has encouraging acute and short-term outcomes.
Journal ArticleDOI
Endovascular stents for coarctation of the aorta: initial results and intermediate-term follow-up
TL;DR: Intravascular stent placement for native and recurrent CoA has excellent results in the short and intermediate terms, and long-term outcome remains to be evaluated.
Journal ArticleDOI
Transcatheter Closure of Perimembranous Ventricular Septal Defects Using the New Amplatzer Membranous VSD Occluder: Results of the U.S. Phase I Trial
Yun Ching Fu,John L. Bass,Zahid Amin,Wolfgang Radtke,Wolfgang Radtke,John P. Cheatham,William E. Hellenbrand,David T. Balzer,Qi Ling Cao,Ziyad M. Hijazi +9 more
TL;DR: Transcatheter closure of a PmVSD is technically feasible and seems safe enough in children over 8 kg in weight to warrant continuation of clinical trials to assess the long-term safety and efficacy.
