Summary
This summary is machine-generated.

Sutureless aortic valve replacement (AVR) is a safe and reproducible option for elderly patients, offering short operative times. However, it is associated with a high rate of permanent pacemaker implantation.

Area of Science:

  • Cardiovascular Surgery
  • Interventional Cardiology
  • Biomaterials Science

Background:

  • Sutureless aortic valve replacement (AVR) is an emerging alternative to standard AVR for high-risk elderly patients.
  • This study reports the initial Canadian experience with sutureless AVR.

Purpose of the Study:

  • To evaluate the early outcomes of sutureless AVR in Canada.
  • To assess the safety, reproducibility, and efficacy of the Perceval S bioprosthesis.

Main Methods:

  • A multicenter study involving 215 patients undergoing sutureless AVR with the Perceval S bioprosthesis.
  • Perioperative clinical and echocardiographic outcomes were assessed.

Main Results:

  • The mean patient age was 79 years, with 54% being women.
  • In-hospital mortality was 4%, with no reported valve migration.
  • A significant rate of permanent pacemaker implantation (17%) was observed, including 9% for complete atrioventricular block.

Conclusions:

  • Sutureless AVR with the Perceval S prosthesis is safe, reproducible, and associated with short operative times.
  • Echocardiographic results show low gradients and no paravalvular aortic insufficiency.
  • A high risk of permanent pacemaker implantation is a key consideration for this procedure.
