Lerato Mbongo and Opheleleyo
Double belted! Opheleleyo Qwabe and Lerato Mbongo revel in the moment.

Their friendship began in high school, where they were constantly told by teachers that they would not make it to university, but these best friends never gave up. On Thursday 21 April 2022, they received their honours degrees in the Faculty of Natural and Agricultural Sciences together during the afternoon ceremony of the University of the Free State’s April Graduations.

Lerato Mbongo and Opheleleyo Qwabe, who have been friends since Grade 9, said being picked on in class for not being the brightest learners brought them together and motivated them to work harder.Mbongo obtained a Bachelor of Agriculture Honours majoring in Wildlife Management, and Qwabe received a Bachelor of Agriculture Honours majoring in Agricultural Economics.

“We’ve always dreamed big, but if you had told us back then that we would one day be two-time graduates, we wouldn’t have believed it. During one of our Maths lessons back in Grade 9, our teacher went around asking the ‘smarter’ kids what they wanted to study after matric, but when he got to us, he said there was no point in asking because we wouldn’t make it that far anyway,” Qwabe said.

The friends, who both started at the university’s South Campus, said they were grateful for the UFS Preparation Programme, as it boosted both their marks and their confidence. “The programme helped us to believe in ourselves again, and also played a big role in helping us discover what we wanted to study. The courses we enrolled in really unlocked an unstoppable passion in us and helped us realise that nothing is impossible. Today, here we are celebrating 10 years of friendship, and our honours degrees. We’ve conquered once again, and we're sharing our victories together,” Mbongo said.

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.
