p Values relate to comparisons with SPAP 1.

AMVSDO, Amplatzer muscular ventricular septal defect occluder diameter; CC, complete closure; SAOP, systolic aortic pressure; SPAP 1, systolic pulmonary artery pressure before balloon occlusion; SPAP 2, systolic pulmonary artery pressure during balloon occlusion.
