  • Title: [Posterior Mitral Leaflet Patch Augmentation with Autologous Pericardium in a Neurofibromatosis TypeⅠPatient:Report of a Case].
    Author: Gon S, Miyazaki T, Kato I, Asakawa N.
    Journal: Kyobu Geka; 2021 Nov; 74(12):1012-1016. PubMed ID: 34795144.
    Abstract:
    The patient was a 61-year-old man with neurofibromatosis typeⅠ, who had several papules in a whole body. Medical history included atrial fibrillation and cerebral embolism. Transthoracic and transesophageal echocardiogram revealed severe mitral valve regurgitation and tricuspid valve regurgitation due to annular dilation with atrial enlargement, tethering of the posterior mitral leaflet, the anterior mitral leaflet prolapse with chordal rupture. Mitral valve repair and tricuspid annuloplasty, maze procedure were performed via median sternotomy. Mitral valve repair was performed by chorda reconstruction with artificial chordae to A2, patch-augmentation of the posterior leaflet with 0.6% glutaraldehyde-treated autologous pericardial patch and ring annuloplasty. There was no abnormal bleeding during surgery, and surgical site infection was not observed. Postoperative echocardiogram showed the augmented posterior leaflet created a deep and tightly uniform coaptation to the anterior leaflet and mitral regurgitation was well controlled.
