Kovsies aim top 6 in Varsity hockey Cheslyn Neethling
Cheslyn Neethling will lead the Kovsie men’s hockey team in the Varsity Hockey tournament.

The Kovsie men’s hockey team hope to draw inspiration from their victory over the North-West University recently when they face their old rivals in the opening round of the Varsity Hockey tournament.

The tournament for men, which is contested biannually, starts on Friday 4 May 2018.

The Kovsies played the Pukke in two matches in Potchefstroom at the end of March with both sides on the winning side once each.

According to the coach Braam van Wyk it will give them a lot of confidence when they come up against the Pukke on Friday afternoon (4 May) in Johannesburg.

“We hope to finish in the top six, anything better than that will be a bonus,” said Van Wyk, in his third year as coach of the team.

They reached the semi-final in 2014 and ended seventh in 2016.

It is a short tournament of just two-and-a-half weeks with the final on 21 May 2018. 

On Saturday 5 May they tackle the University of Johannesburg who won the inaugural men’s tournament in 2014 and defended it in 2016.

The Madibaz lay in wait on Sunday 6 May and on Monday 7 Mayat the University of Cape Town. 

Van Wyk, who played for the Kovsies between 2006 and 2009, said he is in favour of the power play. Each side has one in a match. For three minutes the team will be without two players, with goals worth two points. In addition, all field goals are worth two points. If a match is drawn it will go straight to a shootout.

The Kovsies are led by Cheslyn Neethling. Two players, Egon van der Merwe and Jan Willem Ras, will feature in their third Varsity tournament.

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.
