Abstract

Aims The aim of this study was to evaluate the efficacy and safety of transcatheter aortic valve implantation (TAVI) in patients of small body size (SB). Methods and Results Between October 2006 and November 2011, 424 patients undergoing TAVI were evaluated. Patients with a small body surface area (BSA; <1.75 m2) were defined as the "SB group" (n = 215) and the remaining large BSA patients as the "LB group" (n = 209). In the SB group, mean annulus diameter measured by CT and minimal femoral artery diameter were significantly smaller (23.1 ± 1.92 vs. 24.3 ± 1.91 mm, P < 0.01; 7.59 ± 1.06 vs. 8.29 ± 1.34 mm, P < 0.01, respectively). The logistic EuroSCORE was similar between groups (22.5 ± 10.4 vs. 23.4 ± 12.0; P = 0.43). Equivalent device success (91.2% vs. 91.4%; P = 0.94) and 30-day survival rates (85.1% vs. 87.6%; P = 0.46) were achieved in both groups. Vascular complications and the 30-day combined safety end point rate were significantly higher in the SB group (13.0% vs. 4.3%, P < 0.01; 27.4% vs. 18.3%, P = 0.03, respectively). Similar post-procedural mean pressure gradient was achieved in both groups (10.2 ± 4.3 vs. 11.0 ± 4.6 mmHg; P = 0.12). Multivariate analysis showed that BSA was one of the independent predictors of 30-day combined safety end point (Odds ratio: 0.20; 95% confidence interval (CI): 0.05-0.88; P = 0.03). However, Kaplan-Meier analysis revealed no significant difference in mid-term survival rate between groups (log-rank P = 0.64). Conclusions TAVI in SB patients resulted in similar clinical outcomes with effective post-procedural hemodynamics compared with LB patients. Care should be taken to avoid vascular complications in SB patients.
