Cerebral ischemic injury after transcatheter aortic valve replacement in patients with pure aortic regurgitation
J Zhejiang Univ Sci B. 2023 Jun 15;24(6):530-538. doi: 10.1631/jzus.B2200444.ABSTRACTConsidering the surgical risk stratification for patients with severe calcific aortic stenosis (AS), transcatheter aortic valve replacement (TAVR) is a reliable alternative to surgical aortic valve replacement (SAVR) (Fan et al., 2020, 2021; Lee et al., 2021). Despite the favorable clinical benefits of TAVR, stroke remains a dreaded perioperative complication (Auffret et al., 2016; Kapadia et al., 2016; Kleiman et al., 2016; Huded et al., 2019). Ischemic overt stroke, identified in 1.4% to 4.3% of patients in TAVR clinical practice, has be...

Self-expanding TAVR as good as surgery in intermediate-risk patients
Two-year data reveal no difference in the combined rate of stroke and death from any cause when comparing the use of self-expanding transcatheter aortic valve replacement (TAVR) with standard open-heart surgery in intermediate risk patients with severe aortic stenosis, according to research.

Rates of death and stroke equivalent for surgery and TAVR at two years
Intermediate-risk patients with severe aortic stenosis who receive minimally invasive transcatheter aortic valve replacement, known as TAVR, have similar rates of death and disabling strokes after two years compared with those undergoing standard open heart surgical replacement, according to a new study. Patients receiving TAVR also experienced shorter hospital stays and lower incidence of some major complications compared with those undergoing surgery.

SAPIEN 3 improves 30-day outcomes for major endpoints, study suggests
The SAPIEN 3 heart valve demonstrated lower death, stroke and paravalvular leak rates than earlier generation devices in patients at high risk for surgery and showed encouraging results in intermediate-risk patients, according to new research.

Aortic valve replacement appears safe, effective in very elderly patients
Aortic valve replacement (AVR) can safely be used to treat severe aortic stenosis in patients age 90 years and older and is associated with a low risk of operative stroke and mortality, according to a study.
