Outcomes and Predictors of Different Flow-Gradient Patterns of Aortic Stenosis Following Transcatheter Aortic Valve Replacement.
Am J Cardiol

Department of Cardiovascular Medicine, Heart, Vascular and Thoracic Institute, Cleveland Clinic, Cleveland, Ohio, USA. Electronic address:
This study sought to explore the clinical factors associated with classical low-flow low-gradient (C-LFLG) and normal-flow low-gradient (NFLG) aortic stenosis (AS) compared to high-gradient (HG) AS. We also compared clinical and echocardiographic outcomes after transcatheter aortic valve replacement (TAVR) across flow-gradient patterns. Patients with C-LFLG AS have a higher mortality rate after TAVR than those with HG AS.

Objective: Percutaneous vegetation debulking has been reported to treat tricuspid valve infective endocarditis (TVIE), but data on feasibility compared with conventional surgical strategies are limited. We aimed to compare short-term outcomes of suction debulking with partial venovenous bypass to conventional open surgery in this population.
Methods: This was a single-center, retrospective study that included all patients with isolated TVIE who underwent suction debulking with partial venovenous bypass or tricuspid valve surgery between January 2010 and December 2022.

Background: Patients with severe tricuspid regurgitation (TR) typically present with heterogeneity in the extent of cardiac dysfunction and extra-cardiac comorbidities, which play a decisive role for survival after transcatheter tricuspid valve intervention (TTVI).
Objectives: This aim of this study was to create a survival tree-based model to determine the cardiac and extra-cardiac features associated with 2-year survival after TTVI.
Methods: The study included 918 patients (derivation set, n = 631; validation set, n = 287) undergoing TTVI for severe TR.

Elastic Recoil and Deployment Asymmetry of the Transcatheter Heart Valve in Bicuspid Versus Tricuspid Anatomy.

Department of Cardiovascular Medicine, Heart, Vascular and Thoracic Institute, Cleveland Clinic, Cleveland, Ohio, USA.
Background: Data supporting the use of transcatheter aortic valve replacement (TAVR) for bicuspid aortic valve (BAV) is limited compared to tricuspid aortic valve (TAV) anatomy, as the BAV anatomy poses unique challenges to prosthesis expansion and symmetric deployment.
Aims: We aim to compare the acute recoil and asymmetry of the SAPIEN-3 valve between BAV and TAV anatomies and their impact on procedural outcomes.
Methods: We conducted a single-center study of patients who underwent TAVR with the SAPIEN-3 valve.
