OBJECTIVES This study sought to present the U.K. experience to date with the second-generation LOTUS bioprosthesis (Boston Scientific, Natick, Massachusetts). BACKGROUND First-generation transcatheter aortic valves have limitations. Second-generation repositionable valves may improve on some of those limitations. METHODS Prospectively collected data(More)
BACKGROUND Surgical risk scoring systems are poor at predicting outcome in patients undergoing transcatheter aortic valve implantation (TAVI). Frailty indices might more accurately predict outcome. AIMS To examine multiple frailty indices as markers of performance to see whether they predict outcomes both in the shorter (30 days) and longer terms (5(More)
INTRODUCTION AND METHOD Transcatheter aortic valve implantation (TAVI) and balloon aortic valvuloplasty (BAV) are now well established percutaneous procedures. These procedures almost always require bursts of rapid ventricular pacing to temporarily reduce cardiac output to facilitate the procedure, usually done via a temporary pacing wire inserted into the(More)
Patent foramen ovale has been identified as a conduit for paradoxical embolism resulting in cryptogenic stroke or transient ischemic attack (TIA). We aimed to establish rates of death, recurrent stroke or TIA among patients undergoing PFO closure for stroke or TIA at our unit. A retrospective analysis of all PFO closure patients was performed between May(More)
BACKGROUND Surgical risk scoring systems are of modest value in predicting outcome following transcatheter aortic valve implantation (TAVI). There is no consensus as to which scoring system is the most useful. We examined the efficacy of all four currently available global scorings systems (Additive EuroScore [aES], Logistic EuroScore [LES], EuroScore II(More)
BACKGROUND Redo surgery for degenerative bioprosthetic aortic valves is associated with significant morbidity and mortality. Report results of valve-in-valve therapy (ViV-TAVI) in failed supra-annular stentless Freedom Solo (FS) bioprostheses, which are the highest risk for coronary occlusion. METHODS Six patients with FS valves (mean age 78.5 years, 50%(More)
OBJECTIVE To assess the success rate and safety outcomes of left atrial appendage occlusion (LAAO) procedures in a cohort of patients who had not undergone preprocedural imaging. BACKGROUND LAAO patients usually undergo imaging with either transesophageal echocardiography (TEE) or computed tomography (CT) prior to the procedure itself. This preprocedural(More)
OBJECTIVES The authors report the incidence of pacemaker implantation up to hospital discharge and the factors influencing pacing rate following implantation of the LOTUS bioprosthesis (Boston Scientific, Natick, Massachusetts) in the United Kingdom. BACKGROUND Transcatheter aortic valve replacement (TAVR) is associated with a significant need for(More)
Transcatheter aortic valve implantation (TAVI) has become the standard treatment for aortic stenosis in high-risk patients. TAVI for native valve aortic regurgitation is technically more demanding because of a lack of anchoring calcification, a lower index incidence, heterogeneous causes, and larger anatomy. We present 3 cases in which the Lotus TAV was(More)
