Journal ArticleDOI
A Leadless Intracardiac Transcatheter Pacing System
Dwight Reynolds,Gabor Z. Duray,Razali Omar,Kyoko Soejima,Petr Neuzil,Shu Zhang,Calambur Narasimhan,Clemens Steinwender,Josep Brugada,Michael Lloyd,Paul R. Roberts,Venkata Sagi,John D. Hummel,Maria Grazia Bongiorni,Reinoud E. Knops,Christopher R. Ellis,Charles C. Gornick,Matthew A. Bernabei,Verla Laager,Kurt Stromberg,Eric R. Williams,J. Harrison Hudnall,Philippe Ritter +22 more
TL;DR: The transcatheter pacemaker implanted in patients who had guideline-based indications for ventricular pacing met the prespecified safety and efficacy goals; it had a safety profile similar to that of a transvenous system while providing low and stable pacing thresholds.
Journal ArticleDOI
Clinical efficacy of sildenafil in primary pulmonary hypertension: A randomized, placebo-controlled, double-blind, crossover study
TL;DR: Sildenafil significantly improves exercise tolerance, cardiac index, and QOL in patients with PPH in a randomized, double-blind, crossover design.
Journal ArticleDOI
Neuraxial Modulation for Refractory Ventricular Arrhythmias: Value of Thoracic Epidural Anesthesia and Surgical Left Cardiac Sympathetic Denervation
Tara Bourke,Marmar Vaseghi,Yoav Michowitz,Vineet Sankhla,Mandar Shah,Nalla Swapna,Noel G. Boyle,Aman Mahajan,Calambur Narasimhan,Yash Lokhandwala,Kalyanam Shivkumar +10 more
TL;DR: It is suggested that TEA and LCSD may be effective additions to the management of refractory ventricular arrhythmias in structural heart disease when other treatment modalities have failed or may serve as a bridge to more definitive therapy.
Journal ArticleDOI

TL;DR: A deletion of 25 bp in the gene encoding cardiac myosin binding protein C (MYBPC3) is described that is associated with heritable cardiomyopathies and an increased risk of heart failure in Indian populations.
Journal ArticleDOI
Long-term performance of a transcatheter pacing system: 12-Month results from the Micra Transcatheter Pacing Study.
Gabor Z. Duray,Philippe Ritter,Mikhael F. El-Chami,Calambur Narasimhan,Razali Omar,José María Tolosana,Shu Zhang,Kyoko Soejima,Clemens Steinwender,Leonardo Rapallini,Aida Cicic,Dedra H. Fagan,Shufeng Liu,Dwight Reynolds +13 more
TL;DR: Long-term performance of the Micra transcatheter pacemaker remains consistent with previously reported data, and few patients experienced major complications through 12 months of follow-up, and all patient subgroups benefited as compared to transvenous pacemaker historical control group.
