back towards the VSD under fluoroscopic and trans- thoracic echocardiographic guidance (Figure 3C). The RV disc was exteriorized 1–2 cm distal to the defect while avoiding entrapment of the chordal elements of the tricuspid valve. The whole system was then further withdrawn till the RV disc was firmly seated on the RV aspect of the defect. Keeping it steady, the
sheath alone was then further pulled back to succes- sively deploy the waist and finally the LV disc of the device. Check angiography was performed through the side arm of the delivery sheath by hand injection to confirm device position. TTE was also performed to visualize the placement of the device on the defect, function of the tricuspid, mitral, and aortic valves and
