In a specially extended episode recorded in front of an audience at the BBC Radio Theatre in London, What's up Docs? explores the wonders of the human heart.

"The heart is more than just a pump—it's a marvel of engineering and history, and in this episode, we're pulling it apart to see how it all works!”

Join Drs Chris and Xand van Tulleken as they discover how reliable the human heart can be - beating on average a hundred thousand times a day - that's more than 2.5 billion beats in a lifetime!

The doctors are joined on stage by Sian Harding, Emeritus Professor of Cardiac Pharmacology at the National Heart and Lung Institute, Imperial College London. She is also author of The Exquisite Machine: the new science of the hear. Sian tells us that far from being fragile, the human heart is a marvel of engineering, in fact, to get a washing machine to perform as well as the heart, it would have to run a wash cycle continiously for a 1000 years!

Also taking part is Prof Stephen Westaby, one of the world's leading heart surgeons, whose pioneering procedures have made front page news around the world. Over the course of his career, he has performed over 11,000 heart operations and is renowned for his groundbreaking work in artificial heart technology.

Together they look back at the history of heart surgery, reveal some of the latest breakthroughs in heart science, including the future of artificial hearts, and discuss how you can best to look after your own heart.
