Research “A new technique to deliver semi lunar valve replacements may well be the one most vital step in viscus innovation ever undertaken,” says leading heart specialist, Dr Michael Mahmoudi, Clinical Senior Lecturer In Cardiological Science at the University of Surrey.

According to Dr Mahmoudi, the event of approach|a method} understand as trans catheter semi lunar valve implantation (TAVI) is about to vary the way stenosis, that happens once the semi lunar valve becomes narrowed and obstructs the blood flowing through it, is treated.

At present semi lunar valve replacement, performed through heart surgery, is performed on regarding five,000 people annually. the method involves cutting the chest of a patient to access the center. the heart is then stopped and a heart-lung bypass machine is employed to require over the circulation throughout the operation. The semi lunar valve is removed and replaced with either a tissue or a metal valve. the center is then started once more and also the chest incision is closed.

Whilst the procedure is incredibly effective, patients typically stay in hospital for 5 to 6 days once surgery and won’t feel the complete advantages of the replacement for up to a few to 6 months. people who have a metal instead of a tissue valve inserted will got to take blood-thinning medication, like anticoagulant, indefinitely.

Perhaps most notably, there area unit an oversized proportion of individuals who want associate semilunar valve replacement, except for whom the present procedure is simply too dangerous. This includes the terribly old, those with pre-existing conditions, like diabetes or kidney failure, anyone who has suffered a stroke or people who have had operation.

With TAVI, the risks area unit greatly reduced giving a lot of individuals the chance to access the life saving procedure. “The method is way less intrusive,” explains Dr Mahmoudi. “Instead of open surgical process, the new valve is guided  into place employing a tube that's inserted into the arterial through the groin.”

TAVI is administered using delicate anesthesia referred to as conscious sedation. The patient can solely be needed to remain in hospital for around 3 to four days and among per week they ought to feel the advantage of the new valve. With bigger accessibility, fewer risks, a faster recovery time and lower prices for the NHS, the advantages area unit instantly evident.

The first randomised controlled trial of TAVI was printed in 2011, therefore knowledge is restricted to the last 5 years. However, as Dr Mahmoudi explains, “there are variety of major studies all showing positive results and also the longevity of the valve replacement. We’ll still monitor patients, however among succeeding 5 to ten years, TAVI may well be the quality procedure for semilunar valve replacement.”

Dr Mahmoudi leads analysis for the Ashford and St Peter’s NHS Foundation Trust unitedly with Surrey University and also the Trust analysis Department.
