BACKGROUND: Percutaneous edge-to-edge mitral valve repair technique (MitraClip) is a widely used treatment for mitral regurgitation (MR) in patients assessed with high surgical risk or inoperability. Only limited experiences with this highest-risk patient population exist. Procedural failure for MitraClip or recurrent MR is a strong predictor of 1-year mortality. Open mitral valve surgery constitutes the last bailout for patients within this cohort.
METHODS: This retrospective single-center cohort study analyzed 17 mitral valve surgery patients after failed MitraClip. We, therefore, analyzed a high-risk patient population (EuroSCORE II = 10 ± 2.0) with persistent mitral valve regurgitation, which was mainly caused by detachment or dislocation of the MitraClip.
RESULTS: Symptomatic patients with failed MitraClip need a convenient operation (mean time to mitral valve surgery = 23 ± 44 days). The patient's collective showed many complex reoperations with the need for concomitant surgery. Considering the high-risk patient population, we showed an average 30-day all-cause mortality (18%, n = 3) accompanied by typical postoperative complications related to prolonged mechanical ventilation (44 ± 48 h) and ICU stay (11 ± 11 days), reflecting high-risk patients. Further, excellent valve-related outcomes were shown regarding adverse cardiac events (valve-related mortality 6%, n = 1) and postoperative echocardiographic results (moderate or severe paravalvular leak 6%, n = 1).
CONCLUSION: Failure of MitraClip represents a challenging situation limited by high-risk profiles of patients and limits the possibility of surgical valve repair, shown by a high rate of mitral valve replacement (94%, n = 16). Secondary surgery was associated with moderate 30-day and postdischarge outcomes. Therefore, a careful evaluation of patients undergoing MitraClip is of paramount importance.
