Predictors for Prolonged Hospital Stay After Transcatheter Mitral Valve Repair With the MitraClip®

Objective: The aim is to find predictors for a prolonged LOHS after MitraClip (R) implantation. Background: Due to its less invasive nature, average length of hospital stay (LOHS) after the MitraClip (R) procedure is shorter compared to mitral valve surgery. However, some patients have a prolonged LOHS. Methods: Records of consecutive patients who underwent MitraClip (R) procedure were reviewed. A total of 41 consecutive patients with MitraClip (R) implantation (7669 years, 59% men) were included. Median hospital stay was 7 days. Hospitalization lasting longer than 7 days was considered prolonged. Results: Procedural success was achieved in 88% of the cases. In-hospital death occurred in 4 of 41 patients (10%). Patients with a prolonged hospital stay (46%) had a higher EuroSCORE I (22.7% [IQR 10.3-28.3] vs. 6.7% [IQR 3.5-18.3], P=0.017), a higher STS mortality score (6.1%[(IQR 3.7-7.5] vs. 2.6% [IQR 1.4-4.8]; P=0.043) and a higher STS long-length-of-stay score (18.9% [IQR 11.3-22.5] vs. 9.6% [IQR 6.2-16.1]; P=0.039) as well as a lower estimated glomerular filtration rate (eGFR) (41 ml/min/1.73 m 2 [IQR 19-52] vs. 56 ml/min/1.73 m 2 [IQR 49-62]; P=0.008) than those whose did not. In the multivariate model, lower eGFR was identified as predictor for a prolonged hospitalization. Conclusion: Lower pre-procedure eGFR is independently associated with a longer hospitalization.
