Objective The aim is to find predictors for a prolonged LOHS after MitraClip® implantation. Background Due to its less invasive nature, average length of hospital stay (LOHS) after the MitraClip® procedure is shorter compared to mitral valve surgery. However, some patients have a prolonged LOHS. Methods Records of consecutive patients who underwent MitraClip® procedure were reviewed. A total of 41 consecutive patients with MitraClip® implantation (76 ± 9 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 m2 [IQR 19-52] vs. 56 ml/min/1.73 m2 [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.
