Sutured wound in myxomatous mitral valve one month after repair surgery: Report of two cases

There have been no reports concerning wound healing at the site of the sutu re line in myxomatous leaflets. We microscopically studied the sutured woun ds in two myxomatous posterior mitral leaflets which underwent quadrangular resection of the frail middle segment followed by primary suture. The sutu red wounds had a thick scar which was abundant in collagen fibers about 1 m onth after the repair surgery. This suggests that severe myxomatous degener ation itself would not be a cause of wound dehiscence, and that a sutured w ound could be a cause of rigidity and deformity of leaflets.
