Progressive intermediate-term improvement in ventricular and atrioventricular interaction after transcatheter pulmonary valve replacement in patients with right ventricular outflow tract obstruction

Patients with RVOT obstruction had biventricular systolic and diastolic dysfunction at BL. Relieving RVOT obstruction with TPVR reduced adverse ventricular and compensatory atrioventricular interaction, resulting in progressive biventricular functional improvement and remodeling at early and midterm FU.
