AI Technical Summary
Existing annulus annuloplasty rings are difficult to precisely adjust in size during mitral valve repair, leading to potential adverse repair outcomes such as residual regurgitation, insufficient occlusive length, and high pressure gradients. Furthermore, they require return to cardiopulmonary bypass, increasing surgical risks.
Employing an adjustable 3D ring core and delivery system, the anterior-posterior diameter of the annulusop ring is adjusted postoperatively via a malleable metal core and shape adjustment mechanism. Precise adjustment is achieved after extracorporeal circulation using cables and a housing device, avoiding negative outcomes.
This technique enables precise adjustment of the annulusoplasty ring after cardiopulmonary bypass, reducing adverse repair consequences, avoiding the need to return to cardiopulmonary bypass, and improving the safety and effectiveness of the surgery.
