Purpose: The Logistic Euroscore (LES) and Society of Thoracic Surgeons (STS) score are used to identify high-risk or inoperable patients eligible for percutaneous Mitral Valve (MV) repair, using the edge-to-edge clip technique. We aimed to examine the correlation between LES and STS scores, and the performance characteristics in patients who underwent percutaneous MV repair. Methods: In total, 87 high-risk patients who underwent percutaneous MV repair using edge-to-edge technique between 01-2009 and 01-2013 were included. The performance of the LES and STS scores was evaluated. Results: The mean age of the included patients was 76.6±9.3 years (70.1% male), with a NYHA functional class ≥ 3 in 93.1%. The combination of in-hospital or 30-days mortality rate was 3.4%. The mean LES was 25.2±15.7%, and mean STS score 13.7±8.6%. A LES of ≥ 20% was present in 54% and a STS score ≥ 10% in 61% of patients. The Pearson correlation coefficient showed a moderate association between LES and STS score (r = 0.64, p<0.001). The area under the receiving operating curve for the prediction of in-hospital or 30-days mortality after percutaneous MV repair was 0.75 for LES and 0.66 for STS score. Conclusion: The LES and STS score are inadequate to predict mortality after percutaneous MV repair using the edge-to-edge technique in high-risk patients. Clinical judgment and the heart team should play a key role in selecting patients for percutaneous MV repair.
