In this episode of 'Policy Pod' Giles talks to Professor Neil Bressloff about TAVI, transcatheter aortic valve implantation used in the treatment of aortic heart valve disease. Degenerative heart valve disease is a growing problem in the ageing populations of Europe and North America. Also, tens of millions of people in low- and middle-income countries of the global south, experience valve failure following bacterial throat infections. Importantly, so-called, rheumatic heart valve disease affects large numbers of adults of all ages in these poorer parts of the world. Tap into our channels above and listen to Prof. Neil and about this research.
