Transcatheter Aortic-Valve Implantation for Aortic Stenosis in Patients Who Cannot Undergo Surgery
Martin B. Leon,Craig R. Smith,Michael J. Mack,D. Craig Miller,Jeffrey W. Moses,Lars G. Svensson,E. Murat Tuzcu,John G. Webb,Gregory P. Fontana,Raj Makkar,David L. Brown,Peter C. Block,Robert A. Guyton,Augusto D. Pichard,Joseph E. Bavaria,Howard C. Herrmann,Pamela S. Douglas,John L. Petersen,Jodi J. Akin,William N. Anderson,Duolao Wang,Stuart J. Pocock +21 more
TL;DR: In patients with severe aortic stenosis who were not suitable candidates for surgery, TAVI, as compared with standard therapy, significantly reduced the rates of death from any cause, the composite end point of deathFrom any cause or repeat hospitalization, and cardiac symptoms, despite the higher incidence of major strokes and major vascular events.
Journal ArticleDOI
Transcatheter versus Surgical Aortic-Valve Replacement in High-Risk Patients
Craig R. Smith,Martin B. Leon,Michael J. Mack,D. Craig Miller,Jeffrey W. Moses,Lars G. Svensson,E. Murat Tuzcu,John G. Webb,Gregory P. Fontana,Raj Makkar,Mathew R. Williams,Todd M. Dewey,Samir R. Kapadia,Vasilis Babaliaros,Vinod H. Thourani,Paul J. Corso,Augusto D. Pichard,Joseph E. Bavaria,Howard C. Herrmann,Jodi J. Akin,William N. Anderson,Duolao Wang,Stuart J. Pocock +22 more
TL;DR: In high-risk patients with severe aortic stenosis, transcatheter and surgical procedures for aorti-valve replacement were associated with similar rates of survival at 1 year, although there were important differences in periprocedural risks.
Journal ArticleDOI
A Randomized Comparison of Coronary-Stent Placement and Balloon Angioplasty in the Treatment of Coronary Artery Disease
David L. Fischman,Martin B. Leon,Donald S. Baim,Richard A. Schatz,Michael P. Savage,Ian M. Penn,Katherine D. Detre,Lisa Veltri,Donald R. Ricci,Masakiyo Nobuyoshi,Michael W. Cleman,Richard R. Heuser,David Almond,Paul S. Teirstein,R. David Fish,Antonio Colombo,Jeffrey C. Brinker,Jeffrey Moses,Alex Shaknovich,John N. Hirshfeld,Stephen Bailey,Stephen E. Ellis,Randal Rake,Sheldon Goldberg +23 more
TL;DR: In selected patients, placement of an intracoronary stent, as compared with balloon angioplasty, results in an improved rate of procedural success, a lower rate of angiographically detected restenosis, a similar rate of clinical events after six months, and a less frequent need for revascularization of the original coronary lesion.
Journal ArticleDOI
Transcatheter or Surgical Aortic-Valve Replacement in Intermediate-Risk Patients.
Martin B. Leon,Craig R. Smith,Michael J. Mack,Michael J. Mack,Rajendra Makkar,Lars G. Svensson,Susheel Kodali,Vinod H. Thourani,Murat Tuzcu,D. Craig Miller,Howard C. Herrmann,Darshan Doshi,David J. Cohen,Augusto D. Pichard,Samir R. Kapadia,Todd M. Dewey,Vasilis Babaliaros,Wilson Y. Szeto,Mathew R. Williams,Dean J. Kereiakes,Alan Zajarias,Kevin L. Greason,Brian Whisenant,Robert W. Hodson,Jeffrey W. Moses,Alfredo Trento,David L. Brown,William F. Fearon,Philippe Pibarot,Rebecca T. Hahn,Wael A. Jaber,William N. Anderson,Maria Alu,John G. Webb +33 more
TL;DR: In intermediate-risk patients, TAVR was similar to surgical aortic-valve replacement with respect to the primary end point of death or disabling stroke; surgery resulted in fewer major vascular complications and less paravalvular aorta regurgitation.
Journal ArticleDOI
Transcatheter Aortic-Valve Replacement with a Balloon-Expandable Valve in Low-Risk Patients
Michael J. Mack,Martin B. Leon,Vinod H. Thourani,Raj Makkar,Susheel Kodali,Mark J. Russo,Samir R. Kapadia,S. Chris Malaisrie,David J. Cohen,Philippe Pibarot,Jonathon Leipsic,Rebecca T. Hahn,Philipp Blanke,Mathew R. Williams,James M. McCabe,David L. Brown,Vasilis Babaliaros,Scott M. Goldman,Wilson Y. Szeto,Philippe Généreux,Ashish Pershad,Stuart J. Pocock,Maria Alu,John G. Webb,Craig R. Smith +24 more
TL;DR: Among patients with severe aortic stenosis who were at low surgical risk, the rate of the composite of death, stroke, or rehospitalization at 1 year was significantly lower with TAVR than with surgery.
