Impact of cerebral protection on observed versus predicted in-hospital stroke in a high stroke risk TAVR cohort.

Background: Despite impressive improvements in the safety profile of Transcatheter aortic valve replacement (TAVR), the risk for peri-procedural stroke after TAVR has not declined substantially. In an effort to reduce periprocedural stroke, cerebral embolic protection (CEP) devices have been utilized but have yet to demonstrate benefit in all-comers. There is a paucity of data supporting the utilization of CEP in TAVR patients with an anticipated high risk for peri-procedural stroke.

Increased Rate of New-onset Left Bundle Branch Block in Patients With Bicuspid Aortic Stenosis Undergoing Transcatheter Aortic Valve Implantation (From a National Registry).

There is a growing interest in transcutaneous aortic valve implantation (TAVI) therapy among patients with bicuspid severe aortic stenosis (BAV). Conduction disturbances remain a frequent complication of TAVI, and new-onset permanent LBBB (NOP-LBBB) post-TAVI may be a marker of worse outcomes. We aimed to evaluate the rate of NOP-LBBB following TAVI among patients with BAV as compared to tricuspid severe aortic stenosis (TAV).

Long-Term Functional and Structural Durability of Bioprosthetic Valves Placed in the Aortic Valve Position via Percutaneous Rout in Israel.

There is limited organized "real life" data regarding the long-term structural and functional durability of transcatheter aortic valve implants, a topic of major importance. We assessed the 5-year structural and functional integrity outcomes following trans-catheter aortic valve implantation (TAVI) with both self-expandable and balloon-expandable prosthetic valve devices. This study included 450 consecutive patients who underwent TAVI for severe symptomatic aortic stenosis (AS) between September 2008 and December 2011.

The effect of periprocedural beta blocker withdrawal on arrhythmic risk following transcatheter aortic valve replacement.

Objective: To evaluate the efficacy and safety of periprocedural beta-blocker (BB) discontinuation among patients undergoing transcatheter aortic valve replacement (TAVR) and high degree atrioventricular block (HD-AVB) and/or atrial fibrillation (AF).

Methods: The study population comprised 743 consecutive patients who underwent TAVR between 2009 and 2017 in two high-volume tertiary centers. All patients received chronic BB therapy, and were divided into two groups: (1) BB continuation and (2) BB discontinued 24 hr prior to the procedure.

Transapical Transcatheter Valve-in-Valve Implantation for Failed Mitral Valve Bioprosthesis.

Unlabelled: Background: The rate of mitral bioprosthesis implantation in clinical practice is increasing. Transcatheter valve-in- valve implantation has been described for high risk patients requiring redo valve surgery.

Objectives: To report our experience with transapical valve-in-valve implantation for failed mitral bioprosthesis.
