Chordae Tendineae Repair Techniques: A Literature Review

Abstract

Advancements in cardiac surgery have significantly transformed the management of mitral valve (MV) disease, with chordae tendineae repair techniques emerging as crucial for restoring heart function and preventing heart failure. Among these, the neochord procedure has gained increasing popularity as a primary repair approach. Many studies longitudinally followed patients who received neochord procedures to see their overall, long-term outcomes. In general, these studies found long-term outcomes to be positive, including low rates of disease recurrence and reoperation. Studies continue to demonstrate that the neochord procedure is effective at mitigating MV regurgitation while also improving overall heart function. Complications have been found to be rare for this procedure. These findings position the neochord procedure as a safe, effective, and increasingly preferred surgical option for appropriately selected patients.

While current evidence strongly supports the safety and efficacy of the neochord procedure, future research should focus on large-scale, randomized controlled trials comparing neochord to other minimally invasive and conventional mitral valve repair techniques. Additionally, further studies are needed to evaluate the long-term durability of neochord implants beyond the current follow-up periods, explore patient selection criteria, and optimize procedural techniques to enhance outcomes.
