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 ® 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. Conclusion Lower pre‐procedure eGFR is independently associated with a longer hospitalization. © 2014 Wiley Periodicals, Inc.
