Impact of sheath diameter of different sheath types on vascular complications and mortality in transfemoral TAVI approaches using the Proglide closure device

OBJECTIVE: Evaluation of the impact of the sheath diameter on vascular complications and mortality in transfemoral aortic valve implantation. METHOD: Between 2012 and 2014, 183 patients underwent the procedure using a sheath diameter of 18–24 F. This collective was divided into two groups: group 1, with a sheath diameter of 18F (G1, n = 94), consisted of patients with 18F Medtronic Sentrant and 18 F Direct Flow sheaths, and group 2 with a sheath diameter of 19–24 F (G2, n = 89) consisted of patients with Edwards expandable e-sheath and Solopath sheaths. Perclose-Proglide(®) was used as a closure device in all patients. RESULTS: G1 had significantly more female patients (64.9% vs. 46.1% in G2, p = 0.01) and the average BMI was lower (26 ± 4.5% vs. 27.4 ± 4.7%, p = 0.03). There was no significant difference in the incidence of major and minor vascular complications (G1: 12.8% vs. G2: 12.4%, p = 0.9). 30-day mortality was similar in both groups (G1: 6.4 ± 2.5% [95% CI: 0.88–0.98], G2: 3.7 ± 1.9% [95% CI: 0.92–0.99]. The Kaplan Meier analysis of survival revealed no significant differences either. CONCLUSION: The difference in sheath diameter had no effect on either incidence or severity of vascular complications. There was no impact on mortality either.
