Efficacy outcome of COT. No difference could be observed in (A) mean aortic gradient and (B) paravalvular leakage following TAVR with different deployment techniques. In the COT group, fewer new permanent pacemaker implantations during 30-day follow-up were needed (COT 8.0% vs. Non-COT 16.8%; p = 0.028) (C), and a reduced length of in-hospital stay could be achieved (COT 8.4 ± 4.0 vs. Non-COT 10.3 ± 6.7 days; p = 0.007) (D). COT, cusp-overlap technique; TAVR, transcatheter aortic valve replacement.
