title: Predictors for prolonged hospital stay after transcatheter mitral valve repair with the MitraClip.
abstract: 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 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.
  
  
  CONCLUSIONS
  Lower pre-procedure eGFR is independently associated with a longer hospitalization.
