Tricuspid valve surgery can lead to pacemaker needs. A novel sewing ring extension technique may reduce tension and prevent conduction problems during tricuspid valve replacement.
Area of Science:
- Cardiovascular Surgery
- Biomedical Engineering
Background:
- Tricuspid valve surgery carries a high risk of permanent pacemaker implantation.
- Annular tension from circular prostheses in non-circular annuli may cause conduction abnormalities.
