South Africa: Italian Surgeons Find World's Oldest Artificial Heart Valve Implanted By Chris Barnard 50 Years Ago

[News24Wire] Surgeons in Italy have made a rare discovery while operating on a 60-year-old woman - an artificial mitral valve that is almost 50 years old, and still working perfectly.

(Concordia University) Using high-tech equipment to look at the flow downstream of a bi-leaflet mechanical heart valve, researchers at Concordia have devised a technique to detect obstructions in a type of mechanical heart valve they believe will contribute to safer follow-up methods for cardiologists and their patients.

AbstractMucopolysaccharidoses (MPS) are inborn errors of metabolism produced by a deficiency of one of the enzymes involved in the degradation of glycosaminoglycans (GAGs). Although taken separately, each type is rare. As a group, MPS are relatively frequent, with an overall estimated incidence of around 1 in 20,000 –25,000 births. Development of therapeutic options for MPS, including hematopoietic stem cell transplantation (HSCT) and enzyme replacement therapy (ERT), has modified the natural history of many MPS types. In spite of the improvement in some tissues and organs, significant challenges remain unsol ved, in...

There has been a flurry of news recently about a procedure called trans-catheter aortic valve replacement (TAVR) for the treatment of the common heart condition aortic stenosis (AS). You may even know people who have had this procedure performed. What exactly is TAVR? And what’s all the excitement about? What is aortic stenosis? First, it’s important to understand the condition that TAVR is designed to treat, aortic stenosis. The aortic valve is the last structure of the heart through which blood passes before entering the aorta and circulating throughout the body. The aortic valve has three flaps, called leafl...

Here's a challenge. What do the three images in Figure  1 have in common? The answer reflects activities that took place decades ago. All three of these revolutionary medical devices (the implantable transvenous pacemaker, the hemodialysis unit, and the artificial heart valve) were the result of collaborations between at least one engineer and one phys ician. In fact, the valve in panel C bears the name of the two inventors, engineer M. Lowell Edwards and surgeon Albert Starr, MD. Dr. Starr attended the ASE Scientific Sessions when they were held in Portland, OR in 2014 and described in detail the bold steps that led ...

ConclusionHealthy BV implanted with C-TAH enabled us to study, for the first time, non-degenerated implanted valve in human. Biomaterial passivation by an organized fibrin deposit and formation of EC monolayer on top achieve an optimal hemocompatibility without any modification of pericardial tissue.
