Figure 3: Strategy in densely calcified conduit. Calcified conduits at risk of rupture are initially interrogated with compliant sizing balloons during coronary injection (a) before prestenting of the conduit with a covered stent. This covered stent is later expanded to larger diameter of 20 mm (b) with high-pressure balloons. Once the conduit gradient is eliminated, Melody valve is positioned in the landing zone present (c) and expanded. A competent pulmonary valve is shown in pulmonary arteriogram recorded in lateral view (d). PA: Pulmonary artery, LPA: Left pulmonary artery, LCA: Left coronary artery
