Collagenase delivery strategies: A, Image of collgenase type 4 (CLG-4) application in subject 3 using small cellulose sponges (2×2 mm). B, Bipolar voltage map before and after CLG-4 application in subject 3. Yellow arrows indicate CLG-4 application site. C, Cellulose sponge (0.5×1 cm) tied to the tip of an irrigation catheter. Black arrows indicate CLG-4 solution connected to irrigation lumen. D, Bipolar voltage map of right ventricular inferior epicardium before and after CLG-4 application in subject 5. Dense scar lesion with voltage < 0.5 mV is shown in gray. Yellow arrows indicate CLG-4 application site.
