Leanne Manas

Leanne Manas is a multiple award-winning broadcast anchor, MC, motivational speaker, businesswoman, UNHCR Goodwill Ambassador, and a renowned leader on the South African media circuit. From Oprah Winfrey to Nelson Mandela, Leanne has interviewed an impressive range of public figures, heads of state, thought leaders, and local and international celebrities. She has also been at the forefront of bringing South Africans some of the biggest news stories over the past two decades. 

She is instantly recognisable as the face of morning television – as anchor of Morning Live, a hard-hitting news broadcast that she has been hosting since 2004. She has been the face of the vast majority of breaking news events in an ever-changing South Africa, most notably the death of Nelson Mandela, the dramatic resignation of Jacob Zuma as RSA President, and the death of the Mother of the Nation, Winnie Madikizela Mandela. She has also anchored four general elections, three provincial elections, and four presidential inaugurations. 

Her career has crossed international borders, broadcasting in the United Kingdom, France, the UAE, Mauritius, Ghana, Kenya, Gabon, Switzerland, the Netherlands, and the United States of America. Broadcasting every day throughout a global pandemic has been the latest event that she has been part of. The total shift of how media is consumed has been a fascinating part of her journey. Leanne has been quoted as saying, “Being able to witness and tell the story of our ever-changing lives is my greatest honour.”

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.
