Hypothesis-generating for combined LV reconstruction in ischemic MR; prospective trials needed before practice change.
A 46-year-old man was referred to our hospital due to severe ischemic mitral regurgitation with severe bileaflet tethering and a dilated left ventricle. We performed left ventricular reconstruction and mitral valve annuloplasty combined with papillary muscle relocation. Although left ventricular continued remodeling occurred during follow-up, left ventricular reconstruction and mitral valve annuloplasty combined with papillary muscle relocation provided durable mitral repair, and his functional status was good. Thus, this combined surgical treatment may reduce mitral regurgitation recurrence after mitral valve annuloplasty.

Furukawa et al. (2017) conducted a case report in Severe ischemic mitral regurgitation (n=1). Left ventricular reconstruction and mitral valve annuloplasty combined with papillary muscle relocation was evaluated on Mitral regurgitation recurrence and functional status. Left ventricular reconstruction and mitral valve annuloplasty combined with papillary muscle relocation provided durable mitral repair with no recurrence of mitral regurgitation and good functional status at 32 months.
