The members of the Kovsie tennis team are, from the left, front: Danique Reynders, Reze Opperman, Daniel de Villiers, Ester de Kock, Lienke de Kock, Anandhi Botha, and Janine de Kock (team manager); back: Marnus Kleinhans (coach), Heinrich Willemse, Emke Kruger, Arne Nel, Ryk Kleinhans, Handre Hoffman, and Ruben Kruger.

The country’s number one student team and South Africa’s second-best club. This is the bragging rights earned by the University of the Free State’s (UFS) tennis team after winning the 2019 University Sport South Africa (USSA) Tennis Championship. 

The Kovsie team claimed their ninth consecutive USSA title on Friday 6 December in Stellenbosch, winning all their matches. The team comprised both men and women – a combination which has been in place since 2010. Since 2010, there has been only one name on the USSA trophy, with the Kovsie team winning from 2010 to 2015 and again from 2017 to 2019. The competition was not hosted in 2016.   

In the 2019 USSA final against Maties, Kovsies was declared the winner, with the score 7-1 after completing seven singles matches and one doubles. A match consisted of four men’s singles, four women’s singles, two men’s doubles, two women’s doubles, and two mixed doubles. 

Arne Nel, Ruben Kruger, Handre Hoffman, Heinrich Willemse, Ester de Kock, and Reze Opperman all won their singles in straight sets. Kruger and Willemse combined for a win in the only doubles match.

On their road to victory, the team had wins over the North-West University (Mafikeng Campus), the University of Cape Town, Stellenbosch University, and the University of Pretoria. The victory over the University of Pretoria in the semi-final was revenge for the Sun City University Championship in March, where they denied Kovsies a fourth consecutive crown in that competition.

Another feather in the cap for Kovsie tennis was that two team members, Willemse and Kruger, along with two management members – Marnus Kleinhans and Janine de Kock, respectively UFS tennis coach and team manager – were chosen for the South African team to the World Student Games in July.

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.
