Surgical vs Transcatheter Treatment in Patients With Coronary Artery Disease and Severe Aortic Stenosis.

Background: Severe aortic stenosis (AS) coexists with coronary artery disease (CAD) in approximately 50% of patients. The preferred treatment is combined surgical aortic valve replacement (SAVR) and coronary artery bypass grafting (CABG). However, transcatheter aortic valve replacement (TAVR) along with percutaneous coronary intervention (PCI) has emerged as a viable alternative.

Impact of minimal lumen segmentation uncertainty on patient-specific coronary simulations: A look at FFR.

We examined the effect of minimal lumen segmentation uncertainty on Fractional Flow Reserve obtained from Coronary Computed Tomography Angiography . A total of 14 patient-specific coronary models with different stenosis locations and degrees of severity were enrolled in this study. The optimal segmented coronary lumens were disturbed using intra and inter-operator variations on the segmentation threshold.

Balloon-Expandable versus Self-Expandable Valves in Transcatheter Aortic Valve Implantation: Complications and Outcomes from a Large International Patient Cohort.

Background: Both balloon-expandable (BE) and self-expandable (SE) valves for transcatheter aortic valve implantation (TAVI) are broadly used in clinical practice. However, adequately powered randomized controlled trials comparing these two valve designs are lacking.

Methods: The CENTER-study included 12,381 patients undergoing transfemoral TAVI.

Applications designed to successfully implant in challenging left atrial appendage occlusion cases: a new tool for the interventional cardiologist.

An 85-year-old patient with permanent atrial fibrillation with a DDD pacemaker, and with indication for left atrial appendage occlusion (LAAO). Sent for LAAO due to recurrent gastrointestinal bleedings even on apixaban and with a CHA 2 DS 2 VASc and HAS-BLED scores of 4 and 3 respectively.

Major Bleeding Predictors in Patients with Left Atrial Appendage Closure: The Iberian Registry II.

Introduction And Objective: Major bleeding events in patients undergoing left atrial appendage closure (LAAC) range from 2.2 to 10.3 per 100 patient-years in different series.
