TCT-642 Intentional Laceration of the Anterior Mitral valve leaflet to Prevent left ventricular Outflow tract ObstructioN (LAMPOON) during transcatheter mitral valve implantation: preclinical findings.
Jaffar M. Khan,Toby Rogers,Anthony Z. Faranesh,Adam Greenbaum,Vasilis Babaliaros,Marcus Y. Chen,Robert J. Lederman +6 more
TL;DR: A novel transcatheter transection of the anterior mitral leaflet is proposed for left ventricular outflow tract obstruction, which is a life-threatening complication ofTranscatheter mitral valve implantation (TMVR).
Journal ArticleDOI
TCT-127 Trans-Auricular Intra-Pericardial Tricuspid Annuloplasty (TRAIPTA)
Toby Rogers,Kanishka Ratnayaka,William H. Schenke,Anthony Z. Faranesh,Merdim Sonmez,Dominique N. Franson,Robert J. Lederman +6 more
TL;DR: It is shown that persistent TR after mitral valve surgery is an independent poor prognostic sign and tricuspid valve repair is usually an adjunct to other surgery.
Journal ArticleDOI
TCT-19 Predicting TMVR-Related LVOT Obstruction: Concept of Fluid Mechanics Modeling
Keshav Kohli,Zhenglun Alan Wei,Vahid Sadri,Thomas F. Easley,Eric L. Pierce,John N. Oshinski,Dee Dee Wang,Adam Greenbaum,Norihiko Kamioka,Jaffar M. Khan,Robert J. Lederman,Philipp Blanke,Philipp Blanke,Vasilis Babaliaros,Ajit P. Yoganathan +14 more
TL;DR: A 2-dimensional (2-D) Neo-LVOT cross-sectional area of <189.4 mm2 is thought to increase the risk of LVOTO post-implantation.
Book ChapterDOI
Real-Time Magnetic Resonance Imaging (MRI)-Guided Intervention
TL;DR: This work is developing real-time MRI catheter guidance to provide alternative soft tissue imaging with the expectation that it will enhance and expand the capabilities of catheter-based interventional procedures and avoid ionizing radiation exposure.
Journal ArticleDOI
Closed chest transthoracic perventricular ventricular septal defect closure under real-time MRI
Kanishka Ratnayaka,Christina E. Saikus,Anthony Z. Faranesh,Merdim Sonmez,Israel M. Barbash,Venkatesh K. Raman,Ozgur Kocaturk,Michael C. Slack,Robert J. Lederman +8 more
TL;DR: This work attempts to conduct device closure of ventricular septal defect using catheter techniques through an open chest using real-time MRI, to provide surgical-grade exposure for non-surgical procedures.
