As a Marfan Syndrome patient with aortic dilation, Tal was unimpressed with the options of a Total Root Replacement or Valve Sparing Root Replacement so set about engineering an alternative. 13 years after receiving the first personalised external aortic root support himself, he is now working to extend this surgical option to a wider group of patients with aortic dilation. With NICE IPAC approval, 10 surgical centres up and running, 118 patients successfully treated, and a collective 400+ post operative patient years, PEARS continues to progress.
