CATHETERIZATION & CARDIOVASCULAR INTERVENTIONS. Comparison of transradial coronary procedures via right radial versus left radial artery approach: A meta-analysis

Rachit M. Shah MD, Dhavalkumar Patel MD, MPH, Antonio Abbate MD, Ph, Michael J. Cowley MD, Ion S. Jovin MD, SCD

Introduction: Coronary angiography and angioplasty via transradial approach is shown to be associated with significant reduction in access site complications. Due to a lack of sufficient data, the use of the right or left radial approach is still operator-dependent. We performed a meta-analysis of prospective randomized studies to compare right versus left radial artery approach for coronary procedures.

CATHETERIZATION & CARDIOVASCULAR INTERVENTIONS. Percutaneous coronary artery revascularization procedures in pediatric heart transplant recipients: A large single center experience

Mariel E. Turner MD, Linda J. Addonizio MD, Marc E. Richmond MD, MS, Warren A. Zuckerman MD, Julie A. Vincent MD, Alejandro J. Torres MD, Michael B. Collins MD

Objectives: To describe our experience, at a large pediatric heart transplant center, with percutaneous coronary interventions (PCI) for cardiac allograft vasculopathy (CAV). Background: CAV is a leading cause of late graft failure, mortality, and re-transplantation in pediatric heart transplant (HTx) recipients. Studies of PCI in adult patients have shown some short-term improvements, but no significant change in long-term outcomes. There are limited data on PCI for CAV in pediatric patients. We describe the largest single-center experience to date. Methods: We performed a retrospective chart review of all pediatric HTx recipients who underwent PCI for a diagnosis of CAV from 2005 to 2014. Results: Twenty-three procedures were performed in 13 patients, at a median age of 16.4 years (range 5.6–21.2) and median time from HTx to first PCI of 8.3 years (range 2.9–20.3).

CATHETERIZATION & CARDIOVASCULAR INTERVENTIONS. Transcatheter valve-in-ring implantation of a repositionable valve system for treatment of severe mitral regurgitation

Michael Lauterbach MD, PhD, Bruno Sontag MD, Alexandros Paraforos MD, Ivar Friedrich MD, PhD, Karl-Eugen Hauptmann MD

Introduction: Years after mitral valve surgery, progressive degeneration of reconstructed mitral valves or bioprostheses might lead to severe mitral valve regurgitation. Patients with significant comorbidity, or impaired left ventricular function are poor candidates for redo surgery at an acceptable risk at that later time point.

CATHETERIZATION & CARDIOVASCULAR INTERVENTIONS. Safety and efficacy profile of bioresorbable-polylactide-polymer-biolimus-A9-eluting stents versus durable-polymer-everolimus- and zotarolimus-eluting stents in patients with acute coronary syndrome

Background: Comparative data on long-term safety and efficacy of bioresorbable-polymer-BES versus durable-polymer-EES/ZES in ACS setting have hitherto been lacking. We sought to assess the safety and efficacy of bioresorbable-polymer-biolimus-A9-eluting stents (BES) compared with thin-strut-durable-polymer-everolimus- and zotarolimus-eluting stents (EES/ZES) in patients with acute coronary syndrome (ACS) undergoing PCI.
