Right atrial approach with a single large patch on the
right ventricle and intermediate fixation
In 1996, Mace and associates used a right atrial approach and inserted a
single large patch to cover the right side of the apical muscular
septum, adding intermediate fixation stitches at the junction between
the septum and anterior right ventricular free wall to prevent septal
bulging (Figures 7A, 7B).5
