Automated Suture Securing Technology in Mitral Valve Surgery: A Strategy to Reduce Prosthetic Dehiscence?

ABSTRACT:

Objectives

This study aimed to assess long-term outcomes of automated titanium fasteners versus hand-tied knots in mitral valve surgery.

Methods

In this retrospective, single-centre analysis, 2678 adult patients who underwent mitral valve repair or replacement between November 2008 and November 2024 at the Medical University of Vienna were included. Patients were grouped according to the suture-securing technique used: automated titanium fasteners versus hand-tied knots. The primary endpoint was prosthetic dehiscence (either mitral annuloplasty ring or valve replacement prosthesis) requiring reintervention. Secondary endpoints comprised ischaemic stroke, intracranial bleeding, and all-cause mortality during the follow-up period.
