Abstract

Abstract : Background: Given their advanced age and high comorbidity, individual risk assessment is crucial in patients undergoing transcatheter mitral and tricuspid valve repair. Therefore, we evaluated the use of a comprehensive geriatric assessment score, the multidimensional prognostic index (MPI), for risk stratification in these patients. Methods: We conducted a prospective, observational single-center study, including 226 patients undergoing percutaneous repair for mitral or tricuspid regurgitation. The MPI was calculated preprocedural and covers 8 domains (activities of daily living, instrumental activities of daily living, mental status, nutrition, risk of pressure ulcers, comorbidity, medication, and marital/cohabitation status). We sought to identify an association of MPI score with procedural outcomes and 6-month mortality. Results: A total of 53.1% of patients were stratified as low risk according to MPI (MPI-1 group), 44.2% as medium risk (MPI-2 group), and 2.7% as high risk (MPI-3 group). Procedural efficacy and safety were similar between groups. The estimated survival rate at 6 months was 97±2% in MPI-1 group, 79±4% in MPI-2 group (hazard ratio, 6.90 [95% CI, 2.36–12.2]; P ≤0.001) and 50±20% in MPI-3 group (hazard ratio, 20.3 [95% CI, 4.51–91.3]; P <0.001). An increase in 1 SD of the MPI score (0.14 points, possible range of MPI score 0–1) was associated with a hazard ratio of 2.13 (95% CI, 1.58–2.73; P ≤0.001) for death after 6 months. The risk association of the MPI with mortality remained significant in multivariate analysis including risk factors, such as peripheral artery disease and NT-proBNP (N-terminal pro-B-type natriuretic peptide) levels. Conclusions: A comprehensive geriatric assessment with the MPI score provides additional information on mortality risk beyond established cardiovascular risk factors.
