Khanyisa Chawane (Senior Sportswoman of the Year) and Sne Mdletshe (Junior Sportswoman of the Year) was unable to attend the awards function.

Pakiso Mthembu was recognised for his performances in cross-country and Khanyisa Chawane for her feats on the netball court at the KovsieSport Awards function on Tuesday night.

The two were honoured as the University of the Free State’s Senior Sportsman and Sportswoman of the Year for 2019. Achievements between 1 October 2018 and 30 September 2019 were taken into consideration.

Mthembu was South Africa’s second-best senior male athlete at the IAAF World Cross Country Championships in Denmark earlier this year. He also came second in the senior men’s 10 km category of the South African Cross Country Championships and won a bronze medal at the University Sport South Africa Championships in the 10 000 m. It was the seventh consecutive year and ninth time in the last ten years that the men’s winner came from the athletics code.

Chawane has played in 14 of the last 17 tests for the Proteas. She was a member of the World Cup team in July, where they finished fourth – their best performance in 24 years. She also represented the SA Fast5 team and was named as the player of the tournament in the 2018 Varsity Netball competition.

The Junior Sportswoman of the Year award went to another netballer, Sne Mdletshe. She was the co-captain of the SA U20 team for the Africa Union Sport Council Region 5 games in Botswana, which was won by the team. At the National Championship, she was named the best centre-court player. There was no winner in the Junior Sportsman of Year category this year.

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.
