Transaortic pannus and chordae removal can successfully restore prosthetic mitral valve function in cases of malfunction caused by preserved chordae and pannus, avoiding the need for redo valve replacement.
Both anterior and posterior chordae of the mitral valve are occasionally spared during mitral valve surgery to preserve left ventricular function. In this report, a 43-year-old woman who had undergone mitral valve replacement surgery with anterior and posterior chordal preservation 9 years ago subsequently had mitral valve pannus and anterior chordae covering the prosthetic valve, which led to valve malfunction. Prosthetic mitral valve function was successfully recovered by performing transaortic pannus and chordae removal, avoiding redo mitral valve replacement.

Park et al. (2010) conducted a case report in Prosthetic mitral valve malfunction (n=1). Transaortic pannus and chordae removal was evaluated on Recovery of prosthetic mitral valve function. Transaortic pannus and chordae removal successfully recovered prosthetic mitral valve function in a patient with valve malfunction, avoiding redo mitral valve replacement.
