AI Article Synopsis
- TAVR with a self-expanding supra-annular valve has better long-term outcomes and durability compared to traditional surgical aortic valve replacement (SAVR).
- In a study, a 29-mm Evolut valve was successfully implanted in 4 patients undergoing SAVR, who had various aortic valve conditions.
- Results showed no valve migration, no need for pacemakers, and low pressure gradients post-surgery, indicating the procedure's effectiveness for those not suitable for TAVR.
Article Abstract
The transcatheter aortic valve replacement (TAVR) with a self-expanding supra-annular valve has shown better hemodynamic outcomes and better valve durability at 5 years when compared with a surgical aortic valve replacement (SAVR). It is possible that the benefits of a self-expanding supra-annular valve can be achieved using a surgical approach. An Evolut (Medtronic) transcatheter aortic valve was surgically implanted in 4 patients undergoing SAVR. Standard surgical methods were used. Three patients had native aortic valve disease, and 1 patient had a degenerated surgical bioprosthesis. The measured valve size was 21 mm in 3 patients and 23 mm in 1 patient; all received a 29-mm Evolut. No valve migration was observed. No patients required a pacemaker. Discharge echocardiography showed low aortic valve gradients (arithmetic mean of 5.3 mm Hg). One patient had a mild paravalvular leak. SAVR using a self-expanding supra-annular valve can be successfully performed in patients not amenable to TAVR.

Background: Interleaflet haemorrhage (IH) plays a well-recognized detrimental role in calcified aortic valve disease (CAVD). However, IH-induced fibro-osteogenic responses in valvular interstitial cells (VICs) appear to be triggered under specific pathological conditions. Iron deficiency (ID), a common co-morbidity in CAVD, may influence these responses.

Aortitis, defined as inflammation of the aorta, can lead to aneurysms and dissections. Intra-operative sampling is essential for diagnosis, with many cases presenting asymptomatically as clinically isolated aortitis. Previous studies investigating aortitis in major aortic surgery have been limited by low intra-operative sampling.

The need for a permanent pacemaker (PPM) implantation after surgical aortic valve implantation (SAVR) is a recognized postoperative complication, with potentially long-term reduced survival. From 1987 to 2017, 2500 consecutive patients underwent SAVR with a biological valve with or without concomitant procedures such as CABG or mitral valve repair. Mechanical valves or valves in another position were excluded.

Bioprosthetic aortic valve degeneration (BAVD) is a significant clinical concern following both transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR). The increasing use of bioprosthetic valves in aortic valve replacement in younger patients and the subsequent rise in cases of BAVD are acknowledged in this review which aims to provide a comprehensive overview of the incidence, diagnosis, predictors, and management of BAVD. Based on a thorough review of the existing literature, this article provides an updated overview of the biological mechanisms underlying valve degeneration, including calcification, structural deterioration, and inflammatory processes and addresses the various risk factors contributing to BAVD, such as patient demographics, comorbidities, and procedural variables.
