Prognostic value of a comprehensive geriatric assessment for predicting one-year mortality in presumably frail patients with symptomatic aortic stenosis

Archives of Medical Science, 2021
Introduction Despite suffering a severe aortic stenosis, some patients are denied either surgical or transcatheter aortic valve implantation (TAVI) therapy because of a frail condition.

Defective recovery of QT dispersion following transcatheter aortic valve implantation: Frequency, predictors and prognosis [PDF]

, 2015
Background: Corrected QT dispersion (cQTD) has been correlated with non-uniform ventricular repolarisation and increased mortality. In patients with aortic stenosis, cQTD has been shown improved after surgical valve replacement, but the effects of ...

TAVR in Male Patients With Large Aortic Valve Annuli: A Propensity‐Matched Analysis of Balloon‐Expandable Versus Self‐Expanding Valves

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Trans‐catheter aortic valve replacement (TAVR) in patients with large annuli poses procedural difficulties and possible complications. Aims We sought to compare the peri‐procedural and long‐term outcomes of patients with large annuli undergoing TAVR with self‐expanding (SEV) versus balloon‐expandable (BEV) valves.

Risk factors for paravalvular leak after transcatheter aortic valve replacement [PDF]

, 2019
Objective. To assess risk factors for paravalvular leak (PVL) after transcatheter aortic valve implantation (TAVI) in a large single-center cohort, including measurement of aortic valve calcification using a reproducible method. Methods.

Balloon‐Expandable Versus Self‐Expanding Valves in Low‐Flow, Low‐Gradient Aortic Stenosis: Does Valve Type Matter?

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The optimal choice between balloon‐expandable (BE) and self‐expanding (SE) transcatheter heart valves (THVs) in patients with low‐flow low‐gradient aortic stenosis (LFLG AS) undergoing transcatheter aortic valve replacement (TAVR) remains unclear.

Similar 5-Year Survival in Transfemoral and Transapical TAVI Patients: A Single-Center Experience

Bioengineering, 2023
Transapical transcatheter aortic valve implantation (TA-TAVI) is generally considered to be associated with increased morbidity and mortality compared with transfemoral transcatheter aortic valve implantation TAVI (TF-TAVI). We aimed to compare different

Annular Ellipticity and Sizing Strategy in Transcatheter Aortic Valve Implantation: Independent or Combined Risk Patterns?

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Elliptical annular anatomy has been considered a risk factor for adverse outcomes after TAVI, particularly paravalvular leakage (PVL). Prosthesis oversizing is thought to improve sealing, but the interaction between annular shape and sizing strategy remains unclear.

Radial force and expansion behavior of an elliptical transcatheter aortic valve replacement in a bicuspid aortic valve

Current Directions in Biomedical Engineering
Transcatheter Aortic Valve Replacement (TAVR) is a widely used treatment for severe aortic stenosis, particularly in patients with a high surgical risk. Although initially designed for tricuspid aortic valves (TAV), its use in bicuspid aortic valves (BAV)
