Abbott has introduced a 35mm sized version of its Navitor Vision transcatheter aortic valve implantation (TAVI) system in the UK.
The company has described this the largest valve size, supplied through the smallest delivery system available on the NHS, offering flexibility, accuracy, and stability in a large TAVI valve platform and is being used at King’s College Hospital in London.
Offered in a range of valve sizes to treat native annulus diameters, including the smallest TAVI valve size (23mm), the latest iteration of these devices were first introduced to the UK in July 2024.
Alongside the valve size, the platform features a large cell design to preserve coronary access for future interventions, as well as a highly flexible delivery system, with controlled deployment providing clinicians with the opportunity to achieve single-digit pacemaker rates.
King’s College Hospital in London, an early adopter of the Navitor TAVI system, is one of the first hospitals to start using the new valve size to treat patients who are at high or extreme surgical risk for open-heart surgery.
Rafal Dworakowski, consultant cardiologist at King’s College Hospital, said: “This valve can help improve the way we treat patients, and is an important addition to our range of treatments for heart valve disease.”
