ABSTRACT
BACKGROUND:
The number of MitraClip® implantations increased significantly in recent years. Data regarding the impact of weight class on survival are sparse.HYPOTHESIS:
We hypothesized that weight class influences survival of patients treated with MitraClip® implantation.METHODS:
We investigated in-hospital, 1-year, 3-year, and long-term survival of patients successfully treated with isolated MitraClip® implantation for mitral valve regurgitation (MR) (June 2010-March 2018). Patients were categorized by weight classes, and the impact of weight classes on survival was analyzed.RESULTS:
Of 617 patients (aged 79.2 years; 47.3% females) treated with MitraClip® implantation (June 2010-March 2018), 12 patients were underweight (2.2%), 220 normal weight (40.1%), 237 overweight (43.2%), and 64 obesity class I (11.7%), 12 class II (2.2%), and 4 class III (0.7%). Preprocedural Logistic EuroScore (21.1 points [IQR 14.0-37.1]; 26.0 [18.5-38.5]; 26.0 [18.4-39.9]; 24.8 [16.8-33.8]; 33.0 [25.9-49.2]; 31.6 [13.1-47.6]; p = .291) was comparable between groups. Weight class had no impact on in-hospital death (0.0%; 4.1%; 1.5%; 0.0%; 7.7%; 0.0%; p = .189), 1-year survival (75.0%; 72.0%; 76.9%; 75.0%; 75.0%; 33.3%; p = .542), and 3-year survival (40.0%; 36.8%; 38.2%; 48.6%; 20.0%; 33.3%; p = .661). Compared to normal weight, underweight (hazard ratio [HR] 1.35 [95% confidence interval [CI] 0.65-2.79], p = .419), obesity-class I (HR 0.93 [95% CI 0.65-1.34], p = .705), class II (HR 0.39 [95% CI 0.12-1.24], p = .112), and class III (HR 1.28 [95% CI 0.32-5.21], p = .726) did not affect long-term survival. In contrast, overweight was associated with better survival (HR 1.32 [95% CI 1.04-1.68], p = .023).CONCLUSION:
Overweight affected the long-term survival of patients undergoing MitraClip® implantation beneficially compared to normal weight.Palabras clave
