ABSTRACT

The Bentall procedure introduced in 1968 represents an undisputed cure to treat multiple pathologies involving the aortic valve and the ascending thoracic aorta. Over the years, multiple modifications have been introduced as well as a standardized approach to the operation with the goal to prevent long-term adverse events. The Gelweave Valsalva graft provides a novel manner to more efficiently reconstruct the anatomy of the aortic root either with a valve-sparing procedure or with the implantation of a valved conduit (bioprosthesis or mechanical valve). The prosthesis holds three sections: the collar anchoring the valve; the skirt mimicking the Valsalva, which is suitable for the anastomoses with the coronary arteries; and the main body of the graft, which is designed to replace the ascending aorta. The Gelweave Valsalva graft allows the Bentall operation to be standardized, and it provides a potential for longer durability with reduced adverse events.
