Rigid Ring Versus Flexible Band for Tricuspid Valve Repair in Patients Scheduled for Mitral Valve Surgery: A Prospective Randomised Study.

Background: Tricuspid valve repair for functional regurgitation is effectively performed with different annuloplasty devices. However, it remains unclear whether there are advantages associated with rigid rings compared to flexible bands. This prospective randomised study aimed to compare results of using a flexible band ring versus a rigid ring for functional tricuspid regurgitation in patients undergoing mitral valve surgery.
