Current state of transcatheter mitral valve implantation in bioprosthetic mitral valve and in mitral ring as a treatment approach for failed mitral prosthesis.

Annals of Cardiothoracic Surgery, 2021
With heightened awareness of mitral valve disease and improvement in surgical techniques, the use of mitral valve bioprostheses has increased. There is a large aging population with prior surgical valvular interventions.

Transcatheter aortic valve implantation in patients with a small aortic annulus: performance of supra-, intra- and infra-annular transcatheter heart valves

Clinical Research in Cardiology, 2021
A small aortic annulus is associated with increased risk of prosthesis–patient mismatch (PPM) after transcatheter aortic valve implantation (TAVI). Whether specific transcatheter heart valve (THV) designs yield superior hemodynamic performance in these ...

Transcatheter Valve Unable to Cure Patient–Prosthesis Mismatch of Mosaic Bioprosthesis

The Thoracic & Cardiovascular Surgeon Reports, 2016
Transcatheter aortic valve implantation (TAVI) has been recently established as a less invasive alternative to conventional aortic valve replacement (CAVR) in patients presenting with expected high procedural risk.

“Valve-On-Valve” — an alternative method of surgical treatment of tissue valve dysfunctions

Российский кардиологический журнал, 2019
Every year, the frequency of use of biological prostheses for treatment of valvular heart disease increases.The implantation of a biological prosthesis allows avoiding lifelong anticoagulant therapy, but at the same time it may require further ...

Balloon Fracturing Valve-in-Valve: How to Do It and a Case Report of TAVR in a Rapid Deployment Prosthesis

Journal of Interventional Cardiology, 2022
Transcatheter aortic valve replacement (TAVR) to treat degeneration of bioprosthetic heart valves (BHVs), called as valve-in-valve (ViV), is becoming a key feature since the number of BHVs requiring intervention is increasing and many patients are at ...

Patient Prosthesis Mismatch After SAVR and TAVR

Frontiers in Cardiovascular Medicine, 2022
Patient-prosthesis mismatch (PPM) remains one out of many factors to be considered during decision-making for the treatment of aortic valve pathologies. The idea of adequate sizing of a prosthetic heart valve was established by Rahimtoola already in 1978.
