A source of celebration, anniversaries mark significant events, none more so than the first PEARS procedure performed 20 years ago today. We toast the 1024 lives that are much better than they might otherwise have been.

The PEARS procedure was conceived by Tal Golesworthy. Unhappy with the existing surgical solution to his expanding aorta, Tal created an alternative, and became the first beneficiary of his elegant invention. As Tal says: "May 24th, 2024 marks the 20th anniversary of the first PEARS surgery carried out by John Pepper on my Marfanoid aorta."

PEARS (Personalised External Aortic Root Support)  

A surgical procedure using a bespoke mesh support that wraps around the dilated portion of the aorta to prevent further dilatation and dissection (usually the
aortic root and ascending aorta as shown in the image).  

PEARS is an alternative to the traditional treatment for aortic dilatation which would be an aortic root/ascending aorta replacement with or without replacement of the aortic valve.  


The first PEARS procedure took place in 2004 and much of the surgery has been in people with Marfan syndrome, 73.5% of the first 200 patients undergoing PEARS had MFS (Van Hoof et al, 2016). 

Each patient having PEARS requires a specialist CT scan which is used to create the personalised 3D wrap for their aorta which is then placed during surgery.  

Potential advantages: 

·       usually, the patient does not need to be put on cardiopulmonary bypass 

·       the operation time is shorter 

·       the native aortic valve remains in place which means no anticoagulation medication is needed for a mechanical valve replacement.   


·       This is still a relatively new procedure which requires a specialist surgeon 

·       PEARS is not offered at all centres in the UK, but you can ask for a referral for a second opinion 

·       PEARS will not always be an option and your surgeon will be able to explain the reasons
