Thrombocytopenia after transcatheter aortic valve implantation.

Introduction And Objectives: Thrombocytopenia frequently occurs after transcatheter aortic valve implantation (TAVI) but its impact is poorly understood. We aimed to analyze the incidence, clinical impact, and predictors of acquired thrombocytopenia after TAVI.

Methods: This retrospective multicenter registry included 3913 patients undergoing TAVI with a baseline platelet count of ≥ 100 *10/L.

One-year outcomes after transcatheter aortic valve implantation with the latest-generation SAPIEN balloon-expandable valve: the S3U registry.

Background: Initial data about the performance of the new-generation SAPIEN 3 Ultra (S3U) valve are highly promising. However, evidence about the longer-term performance and safety of the S3U is scarce.

Aims: We aimed to investigate the 1-year clinical and echocardiographic outcomes of transcatheter aortic valve implantation (TAVI) using the S3U compared with its predecessor, the SAPIEN 3 valve (S3).

[Socioeconomic impact of the current management of severe biliary acute pancreatitis: comparative study].

Objetive: Acute pancreatitis of biliary origin is a common gastrointestinal pathology, in which timely management still is the most important. The aims of this research is establish the socioeconomic impact in the current management of severe acute pancreatitis of biliary origin comparing two centers of the third level, one of high socioeconomic population and another of low in Bogotá, Colombia.

Materials And Methods: A retrospective, cross-sectional comparative study was conducted between January 2012 and December 2017, in two hospitals of Bogotá DC.

Center Valve Preference and Outcomes of Transcatheter Aortic Valve Replacement: Insights From the AMTRAC Registry.

Background: Data on outcomes of transcatheter aortic valve replacement (TAVR) using balloon-expandable valves (BEVs) or self-expandable valves (SEVs) as well as the impact of center valve preference on these outcomes are limited.

Objectives: The aim of this study was to compare outcomes of TAVR procedures using third-generation BEVs and SEVs stratified by center valve preference.

Methods: In a multicenter registry (n = 17), 13 centers exhibited valve preference (66.

Development of atrioventricular and intraventricular conduction disturbances in patients undergoing transcatheter aortic valve replacement with new generation self-expanding valves: A real world multicenter analysis.

Background: High degree cardiac conduction disturbances (HDCD) remain a major complication after transcatheter aortic valve replacement (TAVR), especially with self-expandable valves (SEV). Our aim was to investigate peri-procedural and in-hospital modification of atrioventricular and intracardiac conduction associated to new generation SEV implantation, and the development of new HDCD resulting in permanent pacemaker implantation (PPM) in patients undergoing TAVR.

Methods And Results: Three-hundred forty-four consecutive patients with severe aortic stenosis who underwent TAVR with a new generation SEV [Evolut-R/Pro (n = 130), Acurate-neo (n = 79), Portico (n = 75) and Allegra (n = 60)] were included.
