Performing heart surgery with the click of a mouse
Cannot play media. Sorry, this media is not available in your territory.
Dr Muchtiar Khan is one of only two heart surgeons in the Netherlands performing heart surgery with the click of a mouse.
In the film he operates on a patient using a floppy catheter controlled by magnets operated remotely by a computer.
The catheter burns precise spots on the heart to help regulate an irregular heartbeat. There is no anaesthetic, no open heart surgery and the patient is awake throughout the operation.
