Abstract Background: The right ventricle to pulmonary artery conduit (RVPAC) may impair right ventricular (RV) function in patients with functional single right ventricles. Modification of the RVPAC using a ring-reinforced end
with dunked insertion into the RV through a limited ventriculotomy may reduce the impact on RV function.
We compared RV segmental strain between patients with a traditional RVPAC and ring-reinforced RVPAC using
feature tracking cardiovascular magnetic resonance (CMR) imaging. Methods: Patients with CMR examinations
after Stage I operation with RVPAC between 2000 and 2018 were reviewed. Ventricular mass, volumes, late gadolinium enhancement (LGE), and peak radial and… More >
