Personalised external aortic root support (PEARS)

The first stage of the PEARS procedure is a CT scan which is used to create a 3D model of the aortic root. This model is then used to construct a bespoke mesh 'sleeve' for the aortic root. You consultant will surgically place the sleeve around your aorta and root to prevent further dilation.

This is open surgery carried out under general anaesthetic so you'll be asleep. Unlike the conventional surgical treatment to replace the aorta, there's usually no need for cardiopulmonary bypass (heart and lung machine) during the procedure. It's also a shorter operation than an aortic root replacement, normally lasting no more than two hours.

Your consultant will explain in detail the process for creating and implanting a personalised external aortic root support. As you will be having a general anaesthetic during the implantation stage, your consultant will advise how long you should avoid eating and drinking beforehand, as well as the potential benefits, risks and side effects.

You'll spend one or two days in the intensive care unit immediately after you have a personalised external aortic root support. You'll return to the ward and stay there until your consultant discharges you, a total stay of six or seven days.

One of the main benefits of the procedure versus a traditional aortic root replacement is that you won't need anticoagulant therapy afterwards. The valve is supported and it is very unlikely that further surgery will be required.
