Percutaneous implantation of a clip is an experimental technique that focally approximates the edges of the mitral leaflets.
In a study comparing it with surgery (valve repair or replacement) in patients with chronic moderately severe or severe (3+ or 4+) mitral regurgitation at 12 months the efficacy was greater for surgery than percutaneous repair.
However, more major adverse events occurred within 30 days after surgery. Quality of life improved from baseline to 12 months in both groups, but surgery was associated with a transient decrease in quality of life at 30 days.
