Objectives.
We aimed to assess the procedural and clinical results of transcatheter aortic valve replacement (TAVR) for nonraphe bicuspid aortic stenosis (AS) with coronary vs mixed cusp fusion.
Background.
It remains unclear whether cusp fusion morphology affects TAVR outcomes in patients with nonraphe bicuspid AS.
Methods.
This retrospective study enrolled consecutive patients with severe symptomatic AS and type-0 bicuspid aortic valve, who underwent TAVR at our institution between 2012 and 2017.
TAVR outcomes were defined based on the Valve Academic Research Consortium-2 recommendations.
Results.
Compared to patients with mixed cusp fusion (44/71), those with coronary cusp fusion (27/71) had a larger ellipticity index for the aortic annulus (21.9% ± 9.0% vs 15.6% ± 9.3%, p=0.007) and increased left ventricular outflow tract obstruction (31.1% ± 9.4% vs 26.9% ± 7.5%, p=0.04) but comparable rates of second valve implantation (15.9% vs 14.8%), mild paravalvular leakage (PVL, 38.5% vs 30.2%), permanent pacemaker implantation (PPM, 25.9% vs 15.9%), and 30-day mortality (7.4% vs 6.8%).
Use of a first-generation transcatheter heart valve was associated with higher risk for mild PVL (odds ratio (OR) = 4.37; 95% confidence interval (95% CI) = 1.14–16.75; p=0.03) but not PPM (OR = 0.77; 95% CI = 0.22–2.62; p=0.67), whereas a larger oversizing ratio tended to be associated with a higher PPM rate (OR = 1.49; 95% CI = 0.46–4.86; p=0.51) but lower incidence of mild PVL (OR = 0.51; 95% CI = 0.19–1.35; p=0.17).
Conclusions.
In AS patients with type-0 bicuspid valves, cusp fusion morphology does not affect the procedural or clinical results of TAVR.
Use of second-generation transcatheter heart valves may provide more favorable results in such patients.
This trial is registered with NCT01683474.
