Proteas next goal for Khanyisa
Khanyisa Chawane is going places with her netball career. She finds inspiration from God and the people she surrounds herself with.

Netballer Khanyisa Chawane singles out friends, teammates and her Kovsie coach as the ones who have had the biggest hand in promoting her career.

“Coach Burta de Kock has had an impact on me as a player and person. She took me in, groomed me and taught me the ins and outs of becoming the player I am today,” Chawane says.

They picked me up when I was down

“Maryka Holtzhausen (Free State teammate) has played quite a role in my career as a teammate and mentor. Tiisetso Mashele is a very good friend who has always been there to lend a helping hand during the tough times and remind me where my strength comes from. Then there’s Khomotso Mamburu and Sikholiwe Mdletshe who’ve become more than teammates. They understand me and always manage to pick me up when I’m down and there’s never a dull moment when they are around.”

At the age of 22 Chawane is making huge strides on the netball court.

Crowned player of the tournament

Hardly a month after she was named Player of the Tournament of the Brutal Fruit Netball Premier League, her performances at the National Championship mid-July earned her the Player of the Tournament once more. She is the first player to receive these accolades at both these tournaments in the same year. 

“The people I surround myself with keep me motivated in every aspect of my life. The grace of God upon my life is what inspires me to keep going. 

“I would love to represent the Proteas at the Quad Series and Diamond Challenge later this year and also to win the Varsity Netball Series,” Chawane says about future goals.

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.
