Impact of the indexed effective orifice area on mid-term cardiac-related mortality after aortic valve replacement [PDF]

, 2010
Background There has been ongoing controversy as to whether prosthesis-patient mismatch (PPM, defined as indexed effective orifice area (EOAI)

Remote Ischemic Preconditioning Neither Improves Survival nor Reduces Myocardial or Kidney Injury in Patients Undergoing Transcatheter Aortic Valve Implantation (TAVI) [PDF]

, 2020
BACKGROUND: Peri-interventional myocardial injury occurs frequently during transcatheter aortic valve implantation (TAVI). We assessed the effect of remote ischemic preconditioning (RIPC) on myocardial injury, acute kidney injury (AKIN) and 6-month ...

Evolving technology: the TRIFLO tri-leaflet mechanical valve without oral anticoagulation: a potential major innovation in valve surgery

Frontiers in Cardiovascular Medicine, 2023
The aortic valve is the most frequently diseased valve and aortic stenosis (AS) is the most prevalent valvular heart disease in developed countries. The diseased native aortic valve can be replaced by either a biological or mechanical valve prosthesis ...

Bridging aortic valve surgery to 21st century. what can a surgeon do [PDF]

, 2019
Aortic valve stenosis is the most clinically relevant valvular heart disease in the elderlies. Surgical aortic valve replacement (SAVR) represented, for decades, the standard of care for the treatment of severe aortic stenosis.

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.

Time in therapeutic range and risk of thromboembolism and bleeding in patients with a mechanical heart valve prosthesis.

Journal of Thoracic and Cardiovascular Surgery, 2019
OBJECTIVE Oral anticoagulation with vitamin K antagonists is recommended after mechanical heart valve replacement. However, data regarding the association between the quality of vitamin K antagonist treatment and the risk of complications are sparse ...

Comparative study of wall shear stress at the ascending aorta for different mechanical heart valve prostheses [PDF]

, 2019
An experimental study is reported which investigates the wall shear stress (WSS) distribution in a transparent model of the human aorta comparing a bileaflet mechanical heart valve (BMHV) with a trileaflet mechanical heart valve (TMHV) in physiological ...

Numerical simulation of a transcatheter aortic heart valve under application-related loading

Current Directions in Biomedical Engineering, 2018
For the treatment of severe symptomatic aortic valve stenosis, minimally invasive heart valve prostheses have more recently become the lifesaving solution for elderly patients with high operational risk and thus, are often implanted in patients with ...

Effect of Prosthesis-Patient Mismatch on Long-Term Clinical Outcomes After Bioprosthetic Aortic Valve Replacement.

Journal of the American College of Cardiology, 2023
BACKGROUND Prosthesis-patient mismatch (PPM) is common following surgical aortic valve replacement (SAVR). OBJECTIVES The purpose of this study was to quantify the impact of PPM on all-cause mortality, heart failure hospitalization, and reintervention ...
