AI Article Synopsis
Article Abstract
Objective: To determine the frequency of survival, stroke, atrial fibrillation, structural valve deterioration, and length of hospital stay after surgical replacement of an aortic valve (SAVR) with a bioprosthetic valve in patients with severe symptomatic aortic stenosis.
Design: Systematic review and meta-analysis of observational studies.
Data Sources: Medline, Embase, PubMed (non-Medline records only), Cochrane Database of Systematic Reviews, and Cochrane CENTRAL from 2002 to June 2016.
Study Selection: Eligible observational studies followed patients after SAVR with a bioprosthetic valve for at least two years.
Methods: Reviewers, independently and in duplicate, evaluated study eligibility, extracted data, and assessed risk of bias for patient important outcomes. We used the GRADE system to quantify absolute effects and quality of evidence. Published survival curves provided data for survival and freedom from structural valve deterioration, and random effect models provided the framework for estimates of pooled incidence rates of stroke, atrial fibrillation, and length of hospital stay.
Results: In patients undergoing SAVR with a bioprosthetic valve, median survival was 16 years in those aged 65 or less, 12 years in those aged 65 to 75, seven years in those aged 75 to 85, and six years in those aged more than 85. The incidence rate of stroke was 0.25 per 100 patient years (95% confidence interval 0.06 to 0.54) and atrial fibrillation 2.90 per 100 patient years (1.78 to 4.79). Post-SAVR, freedom from structural valve deterioration was 94.0% at 10 years, 81.7% at 15 years, and 52% at 20 years, and mean length of hospital stay was 12 days (95% confidence interval 9 to 15).
Conclusion: Patients with severe symptomatic aortic stenosis undergoing SAVR with a bioprosthetic valve can expect only slightly lower survival than those without aortic stenosis, and a low incidence of stroke and, up to 10 years, of structural valve deterioration. The rate of deterioration increases rapidly after 10 years, and particularly after 15 years.

Introduction And Objectives: The Valve Academic Research Consortium (VARC)-3 definition of the early safety (ES) composite endpoint after transcatheter aortic valve replacement (TAVR) lacks clinical validation. The aim of this study was to determine the incidence, predictors, and clinical impact of ES after TAVR as defined by VARC-3 criteria.
Methods: We performed a multicenter study including 10 078 patients with severe aortic stenosis undergoing transarterial TAVR.
Comparative Analysis of Central and Noncentral Degenerative Mitral Regurgitation Treated With Transcatheter Mitral Valve Edge-To-Edge Repair.

Department of Structural Heart Disease, National Center for Cardiovascular Disease, China & Fuwai Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, Beijing, China.
Background: Mitral valve transcatheter edge-to-edge repair (M-TEER) was initially indicated for central degenerative mitral regurgitation (DMR) lesions, but advancements in technology have enabled successful treatment in an increasing number of noncentral DMR patients.
Aims: This study aims to compare procedural outcomes and prognosis between noncentral DMR patients, outside clinical trial anatomical criteria, and central DMR patients undergoing M-TEER.
Methods: Drug-refractory moderate-to-severe DMR patients treated with M-TEER at Fuwai Hospital from January 2021 to February 2024 were retrospectively analyzed.
Unveiling the impact of pipe materials on water hammer in pressure pipelines: an experimental and numerical study.

Water hammer (WH) is a phenomenon characterized by the rapid opening or closing of valves or pumps in pipelines, resulting in a disruptive noise, intense vibrations, and potential damage to pipes, fittings, structures, and even human safety. While WH arresters are commonly employed to mitigate this issue in smaller plumbing systems, alternative solutions are required for larger applications like power plants. Researchers have proposed the utilization of pipe materials with a low modulus of elasticity in areas prone to WH events, as these materials possess the capability to absorb a significant portion of the resulting vibrations.

Objective: Repaired Tetralogy of Fallot (rTOF), a complex congenital heart disease, exhibits substantial clinical heterogeneity. Accurate prediction of disease progression and tailored patient management remain elusive. We aimed to categorize rTOF patients into distinct phenotypes based on clinical variables and variables obtained from cardiac magnetic resonance (CMR) imaging.
