Mitral valve repair in ventricular functional mitral regurgitation: a simplified technique of papillary muscles relocation

Mitral valve repair techniques in ventricular functional mitral regurgitation are controversial due to ongoing debates about long-term repair durability in the setting of left ventricular remodelling. To address the limitations of conventional annuloplasty, subannular techniques, such as papillary muscle relocation, have been developed. However, the limited reproducibility of these techniques has hindered their widespread adoption. In this context, we introduce a simplified and reproducible method for papillary muscle relocation. This method utilizes transoesophageal echocardiographic guidance and premeasured polytetrafluoroethylene loops to streamline the procedure.
