Impact of Atrial Fibrillation Type on Outcomes of Transcatheter Aortic Valve Replacement for Aortic Stenosis: A Single-Center Analysis.

Background: Atrial fibrillation (AF) is a recognized risk factor for mortality after transcatheter aortic valve replacement for severe aortic stenosis, but the impact of different types of AF on clinical outcomes remains unclear.

Methods: This retrospective study included 982 patients divided into 3 groups: no AF, paroxysmal AF, and nonparoxysmal AF (persistent or permanent). Clinical outcomes were analyzed using inverse probability weighting and multivariate models.

Impact of Flow-Gradient Patterns on Outcomes of Transcatheter Aortic Valve Replacement for Severe Aortic Stenosis with Preserved Left Ventricular Ejection Fraction.

To compare the clinical outcomes of transcatheter aortic valve replacement (TAVR) in patients with severe aortic stenosis (AS) and preserved ejection fraction (pEF) according to flow-gradient status.This retrospective study focused on patients with severe AS and pEF (≥ 50%) undergoing TAVR with newer generation valves (Sapien3/3 Ultra, Evolut Pro/Pro+/FX) between 2018 and 2022 (n = 781). Patients were divided into 3 groups: normal-flow high-gradient (NF-HG, stroke volume index ≥ 35 mL/m and mean pressure gradient ≥ 40 mmHg or peak velocity ≥ 4 m/second), low-flow high-gradient (LF-HG), and paradoxical low-flow low-gradient (pLF-LG) groups.

Effect of Elevated Body Mass Index on Outcomes of Transcatheter Aortic Valve Replacement for Severe Aortic Stenosis.

Background: The association of body mass index (BMI) and an "obesity paradox" with cardiovascular risk prediction is controversial. This study aimed to evaluate the impact of elevated BMI on the outcome of transcatheter aortic valve replacement (TAVR) for aortic stenosis.

Methods: This retrospective study included 1019 patients with a BMI of ≥18.

Impact of prior coronary artery bypass grafting and coronary lesion complexity on outcomes of transcatheter aortic valve replacement for severe aortic stenosis.

Objective: To investigate the impact of prior coronary artery bypass grafting (CABG) and coronary lesion complexity on transcatheter aortic valve replacement (TAVR) outcomes for aortic stenosis.

Methods: Clinical outcomes of TAVR were retrospectively compared between patients with and without prior CABG, and between patients with prior CABG and without coronary artery disease (CAD). The impact of the CABG SYNTAX score was also evaluated in patients with prior CABG.

Impact of coronary artery disease and revascularization on outcomes of transcatheter aortic valve replacement for severe aortic stenosis.

Background/purpose: To evaluate the impact of coronary artery disease (CAD), percutaneous coronary intervention (PCI), and coronary lesion complexity on outcomes of transcatheter aortic valve replacement (TAVR) for aortic stenosis.

Methods/materials: This retrospective study included 1042 patients divided into two groups by the presence or absence of CAD (SYNTAX score 0, no history of revascularization). Propensity score matching was used to compare the two groups.

Improved Hemodynamics With Self-Expanding Compared to Balloon-Expandable Transcatheter Aortic Valve Implantation in Small Annulus Patients: A Propensity-Matched Analysis.

Patients with small aortic annuli (SAA) pose a challenge in patients undergoing aortic valve replacement because of the potential for prosthesis-patient mismatch (PPM). This study aimed to compare the clinical and hemodynamic outcomes of self-expandable valve (SEV) versus balloon-expandable valve (BEV) transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis and SAA. All patients who underwent TAVI for severe native aortic stenosis with a SAA between January 2018 and December 2022 were retrospectively included in the study from a single center.

Impact of mitral stenosis on early and late outcomes of transcatheter aortic valve replacement for aortic stenosis: a single-center analysis.

Objectives: To assess the impact of concomitant mitral stenosis (MS) on early and late outcomes of transcatheter aortic valve replacement (TAVR) for aortic stenosis.

Methods: This study involved 952 patients undergoing TAVR for severe tricuspid aortic stenosis. The patients were classified into 3 groups: without MS, with progressive MS, and severe MS (mitral valve area ≤ 1.

Computed tomography-derived membranous septum length as predictor of conduction abnormalities and permanent pacemaker implantation after TAVI: A meta-analysis of observational studies.

Background: Permanent pacemaker implantation (PPI) after transcatheter aortic valve implantation (TAVI) is associated with higher risk of mortality and rehospitalization for heart failure. Efforts to prevent conduction abnormalities (CA) requiring PPI after TAVI should be made. The membranous septum (MS) length and its interaction with implantation depth (ID-ΔMSID) could provide useful information about the risk of CA/PPI following TAVI.

Alternative Application Technique for the MANTA Vascular Closure Device for Percutaneous Large-Bore Arterial Access Closure: The Fluoroscopic DOT Technique.

Background: Vascular complications are a cause of increased morbidity and mortality when performing percutaneous procedures requiring large-bore arterial access. MANTA vascular closure device (VCD) is currently the only large-bore VCD using an intraluminal foot plate and an extraluminal collagen plug. The traditional depth locator approach might be compromised in; emergent cases without the required measurements, cases of hematoma formation, or other patient, procedure, or operator-specific variables.
