  • Title: Papillary muscle elevation: an alternative subvalvular procedure for selective relocation of displaced posterior papillary muscle in posteroinferior infarction.
    Author: Ueno T, Sakata R, Ueno M, Ueno T.
    Journal: Interact Cardiovasc Thorac Surg; 2007 Feb; 6(1):9-11. PubMed ID: 17669756.
    Abstract:
    Several subvalvular procedures have been developed for relocating one or both displaced papillary muscles. We describe an original procedure--papillary muscle elevation--in which we relocated the posterior papillary muscle selectively, through a small inferior ventriculotomy, and reduced the coaptation depth from 5 mm to zero. Our procedure can be considered for cases of posteroinferior infarction, which is a frequent cause of ischemic mitral regurgitation.
