(LS = large-small; MS = moderate-small; SS = small-small; LM = large-moderate; MM = moderate-moderate; MSM = moderate-small-moderate hole configuration, IDSP = inter-defects septal puncture. The numeric “7” denotes inter-defects distance of ≥7 mm.) Dotted arrowhead line denotes possibility of double device deploymentBack to article page
