What I worry about is the lack of understanding in society around the world that there is a divide in the world between those who have and those who do not.

I have a charity called the Chain Of Hope, where we target children from poor areas where heart surgery is not available, and we offer our services.

Leaving Egypt and the people I loved so much, and the environment I liked, was definitely worth it, because I also have great love for medicine and science.

The nanofibrillar scaffolds designed to guide the process of cellular repopulation is an important step towards prolonging life and enhancing the quality of life for patients with advanced heart disease with defective valve.
