Predictors of permanent pacemaker requirement in aortic stenosis patients undergoing self-expanding valve transcatheter aortic valve replacement using the cusp overlap technique

Frontiers in Cardiovascular Medicine

IntroductionSince TAVR was approved for lower-risk aortic stenosis (AS) patients, managing post-implantation conduction disturbances has become crucial, especially with self-expanding heart valves (SEV).

The importance of tissue science and valve design in relation to durability and hemodynamics of the DurAVR aortic heart valve

Frontiers in Cardiovascular Medicine

IntroductionClinical evidence highlighting the efficacy and safety of transcatheter aortic valve replacement (TAVR) and the 2019 Food and Drug Administration (FDA) approval for TAVR in low-risk (younger) patients has created a demand for durable and long-lasting bioprosthetic heart valve (BHV) leaflet materials.

STS Announces Late-breaker Research to Be Presented at the 2024 Annual Meeting

DAIC

The analysis included 4,798 patients from 207 STS sites who underwent esophagectomy between 2012-2019. Using the Society of Thoracic Surgeons Adult Cardiac Surgery Database , the study covers adult patients who underwent cardiac surgery after an initial TAVR from January 2012 to March 2023.

STS/ACC TVT Registry Insights Reveal Modest Increase in Risk-Adjusted Mortality Post TAVR

American College of Cardiology

Risk-adjusted 30-day mortality after TAVR increased modestly from January 2019 to March 2022 in the U.S., according to an observational cohort study published in JAMA Cardiology. Exploratory analyses were unable to find any site-related, patient-related or process-related factors that explain these findings.

Why Mechanical AVR Valves Still Matter

CardiacWire

Researchers examined STS registry data on ~109k patients ages 40 to 75 years who received isolated bioprosthetic (94k) or mechanical (15k) AVR over 11 years and found that mechanical valve use decreased by about half (from 20% in 2008 to below 10% in 2019).
