Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aimed to evaluate incidence, prognosis and predictive factors of new-onset of persistent left bundle branch block (LBBB) after rapid-deployment aortic valve replacement (RD-AVR) with the IntuityTM bioprosthesis.

It was an observational, retrospective and single-center study. Two hundred and seventy-four consecutive patients without any baseline ventricular conduction disorder or previous permanent pacemaker or defibrillator implantation who underwent RD-AVR with the IntuityTM valve were included. Twelve-lead electrocardiogram and transthoracic echocardiography were performed preoperatively, postoperatively, at discharge, 1-month, and 1-year. Incidence, prognosis and predictive factors of new-onset of persistent LBBB were evaluated.
