The advent of transcatheter mitral chordal replacement techniques has offered an alternative approach that is less invasive and may be more suitable for select patients compared with surgical repair. These systems involve introducing artificial chordae, via catheter, to replace or supplement damaged or elongated natural chordae. These artificial chordae are anchored at one end to the mitral leaflet and the other end to the papillary muscle or directly to the left ventricular apex, restoring the leaflet's coaptation and reducing regurgitation. Early trials and studies suggest promising results in terms of safety and efficacy in reducing MR severity and improving symptoms.
