Iemura et al. (2013) conducted a case report in Acute mitral valve insufficiency / Papillary muscle rupture (n=1). Mitral valve replacement with preservation of whole subvalvular apparatus was evaluated on Papillary muscle rupture. A 67-year-old man developed a posteromedial papillary muscle rupture following chordal-sparing mitral valve replacement, which was successfully treated with surgical removal of the severed muscle.
