It has been a journey filled with mountains, valleys, rivers, and seas.

Growing up a top achiever, I thought life would be smooth sailing, but like most of us, my first rude awakening came when I lost my mother in 2010. I had to learn to rely on myself and others to keep my head above water. I ask for help when I need it, so I use the services of professionals from time to time.
 
One of the most valuable tools I use, is my gift of singing. I call it my cup filler. I have songs for every mood. I have playlists of songs that I sing along to, pieces that help me balance.
   
I have learnt over the years that I need fuel just like a car needs energy. Moreover, a vehicle needs more than just fuel to function efficiently. I apply the same metaphor to my mental well-being. Besides music, I fuel myself up by doing good to others. 

I love spending time with my dogs, and they know how to make me smile without saying much. I have recently started reflective journaling, and I find it very useful to interrogate thoughts that are not healthy for me. Overall, I remind myself that I am not perfect, and that life is about balance. 

When the scale starts tipping to the one side, life will always calibrate itself into balance, and sometimes those calibration moments are when I feel stressed and overwhelmed. Mine is not to go into panic mode, but to work with life towards achieving that balance again. Over the years, I have noted that this process is a never-ending one.

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.
