The increasing incidence of aortic stenosis and greater co-morbidities and risk
profiles of the contemporary patient population has driven the development of
minimally invasive aortic valve surgery and percutaneous transcatheter aortic
valve implantation (TAVI) techniques to reduce surgical trauma. Recent
technological developments have led to an alternative minimally invasive option
which avoids the placement and tying of sutures, known as "sutureless" or rapid
deployment aortic valves. Potential advantages for sutureless aortic prostheses
include reducing cross-clamp and cardiopulmonary bypass (CPB) duration,
facilitating minimally invasive surgery and complex cardiac interventions, whilst
maintaining satisfactory hemodynamic outcomes and low paravalvular leak rates.
However, given its recent developments, the majority of evidence regarding
sutureless aortic valve replacement (SU-AVR) is limited to observational studies
and there is a paucity of adequately-powered randomized studies. Recently, the
International Valvular Surgery Study Group (IVSSG) has formulated to conduct the
Sutureless Projects, set to be the largest international collaborative group to
investigate this technology. This keynote lecture will overview the use, the
potential advantages, the caveats, and current evidence of sutureless and rapid
deployment aortic valve replacement (AVR).
