Valve implant depth alone impacts the need for new PPI. The rate of new PPI increased with increased NCC implant depth. When excluding patients with pre-existing first-degree AV block or RBBB, the rate of new PPI was <10% in the target and shallow subgroups. When excluding patients with any conduction abnormality, the rate of new PPI remained similar. Gray = Overall new PPI rate in subgroup. Dark blue = New PPI rate in subgroup excluding patients with first-degree AV block or RBBB. Light blue = New PPI rate in subgroup excluding all patients with baseline conduction abnormalities.

Abbreviations: AV, atrioventricular; NCC, noncoronary cusp; PPI, permanent pacemaker implantation; RBBB, right bundle branch block.
