Two athletes, both employees of the University of the Free State (UFS), are now giving back to the sport in administrative roles.

Kesa Molotsane and Louzanne Coetzee are making time in their work and training schedules to serve the sports in which they have represented their country – Molotsane in cross-country and Coetzee in the 1 500 m and 800 m T11 category for athletes with a disability.

Coetzee is again heading for the Paralympic Games in Tokyo. She is a nominee for the International Paralympic Committee Athletes’ Council. Six representatives will be chosen at the Paralympics.

Coetzee was recently elected to the South African Sports Confederation and Olympic Committee Athletes’ Commission. She is also an athlete representative of the South African Sports Association for Physically Disabled.

Molotsane was co-opted into the National Executive Committee of University Sport South Africa as an assessor. She is also the new vice-chairperson of the Athletics South Africa Athletes Commission.

“My biggest dream is to enable athletes to dream big, and for their dreams to be recognised. I would like to see them enjoy their sport,” said Molotsane.

“I think I probably missed a lot of opportunities in my career due to a lack of funding, so I don’t want to see anyone face the same situation.”

Molotsane was also recently named as one of two ambassadors for the SPAR Grand Prix Series. 

According to Coetzee, a former member of the Student Representative Council at the UFS, she believes that it is important for a current sportsperson to contribute and give input in their sport. 

“I enjoy leadership, it is perhaps a gift of mine. Serving the sport in that capacity is not something that is too much of an effort or takes too much of my time. I enjoy contributing and to see something move in a direction.”

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
