[Traumatic mitral valve insufficiency after percutaneous mitral valve angioplasty. Mechanisms and surgical technique].
Eighteen patients underwent surgery for traumatic mitral regurgitation following percutaneous mitral valvuloplasty (PMV). Three patients required emergency surgery (delay less than 6 hours). In the remaining cases, the operation was performed one week after PMW (n = 11) or delayed for up to 3 months (n = 4). The operative findings were: ruptured papillary muscle (n = 1); torn anterior leaflets (n = 4), torn posterior leaflet (n = 1), anterior paracommissural tear (n = 3), posterior paracommissural tear (n = 9). Associated lesions included left atrial thrombosis (n = 2) and greater than 1 cm atrial septal defect (n = 4). Conservative mitral valve surgery was possible in over half the cases (n = 10), including two extensive tears of the anterior leaflet. The other patients required mitral valve replacement (n = 8). There were no postoperative complications in any of the patients.
