Impact of Cusp-Overlap View for TAVR with Self-Expandable Valves on 30-Day Conduction Disturbances

METHODS AND RESULTS: We retrospectively compared 257 consecutive patients undergoing TAVR with self-expandable valves using either CON (n = 101) or COVL (n = 156) in four intermediate/low volume centers. There were no significant differences in baseline characteristics between the groups. The 30-day...

Sumario:METHODS AND RESULTS: We retrospectively compared 257 consecutive patients undergoing TAVR with self-expandable valves using either CON (n = 101) or COVL (n = 156) in four intermediate/low volume centers. There were no significant differences in baseline characteristics between the groups. The 30-day incidence of new-onset LBBB (12.9% vs. 5.8%; p=0.05) and PPMI rate (17.8% vs. 6.4%; p=0.004) was significantly lower when using the COVL implantation view. There was no difference between the CON and COVL groups in 30-day incidence of death (4.9% vs. 2.6%), any stroke (0% vs. 0.6%), and the need for surgical aortic valve replacement (0% for both groups). CONCLUSION: Using the COVL view for implantation, we achieved a significant reduction of the LBBB and PPMI rate after TAVR in comparison with the traditional CON view, without compromising the TAVR outcomes when using self-expandable prostheses.
