Tissue engineered heart valves for transcatheter aortic valve implantation: current state, challenges, and future developments

Expert Review of Cardiovascular Therapy, 2020
Introduction The establishment of transcatheter aortic valve implantation (TAVI) has revolutionized the treatment of severe aortic stenosis. However, with TAVI being approved for low-risk patients, valve durability is becoming of central importance. Here,

Mechanical heart valve prostheses

Cardiovascular Pathology, 2003
Abstract Mechanical heart value prostheses have been in use since the 1950s. Many prostheses have been used for a while and then discontinued. Today, there are a large number and variety of prostheses in use and an even larger variety that are in place in patients. These may be explanted at any time for a number of reasons.

Poorly suited heart valve prostheses heighten the plight of patients with rheumatic heart disease.

International Journal of Cardiology, 2020
Rheumatic heart disease (RHD) still affects more patients globally than degenerative valve disease. The vast majority of these patients live in low- to middle-income countries. Once symptomatic, they will need heart valve surgery.

Identification of mechanical prosthetic heart valves based on distinctive cinefluoroscopic and echocardiographic markers

International Journal of Artificial Organs, 2019
The past 65 years have witnessed remarkable progress in the development of safe, hemodynamically favorable mechanical heart valves. Today, there are a large number and variety of prostheses in use and many prostheses have been used for a while and then ...

Thromboembolic complications of heart valve prostheses

American Heart Journal, 1971
Abstract One hundred seventy patients with prosthetic heart valves receiving anticoagulant therapy have been followed at one to four week intervals for three to sixty-eight months (mean: 26 months). The overall incidence of late emboli was 16 per cent.

Alloplastic materials for heart-valve prostheses

Medical & Biological Engineering & Computing, 1980
Alloplastic materials have found wide application in heart-valve prostheses, in spite of the need for permanent anticoagulant treatment. Though biological valves exhibit excellent thromboresistance, they fail in long-term application because of a disintegration of the tissue structure.

Heart valve prostheses

2015
Abstract Echocardiography is the single most-useful imaging modality to assess heart valve prosteses function. In the majority of patients, transthoracic echocardiography (TTE) is sufficient to assess baseline prostehsis hemodynamics and routine follow-up studies.
