The aortic valve is a highly dynamic structure characterized by a transvalvular flow that is
unsteady, pulsatile, and characterized by episodes of forward and reverse flow patterns …

Background Transcatheter aortic valve replacement (TAVR) is a less invasive treatment than
surgery for severe aortic stenosis. However, its use is restricted by the fact that many patients …

Heart valve replacement is an effective therapy for patients with moderate to severe valvular
stenosis or regurgitation. Most bioprosthetic heart valves applied clinically are based on …

We conducted a retrospective study using the NIS database from 2008 to 2018 to examine
the most contemporary national hospitalization trends of transcatheter (TAVR) and surgical …

Background Pre-procedural computed tomography (CT) imaging assessment of the aortic
valvular complex (AVC) is essential for the success of transcatheter aortic valve replacement …

Background Aortic stenosis (AS) is the most common form of valvular heart disease with an
increasing prevalence. Management of AS has changed dramatically with the introduction of …

Abstract Background and Objective The rapid expansion of TAVR to younger, low-risk
patients raises concerns regarding device durability. Necessarily, extended stent lifetime will …

Methods We performed a national analysis using the NIS database to evaluate predictors of
acute kidney injury (AKI) after TAVR. Our study period was from 2015 to 2018, and we …

Background Left ventricular outflow tract (LVOT) calcification is known to be associated with
adverse outcomes after transcatheter aortic valve implantation (TAVI) in patients receiving …

Catheter reaction forces during transcatheter valve replacement (TAVR) may result in injury
to the vessel or plaque rupture, triggering distal embolization or thrombosis. In vitro test …
