Giant coronary artery aneurysm in an adult

After predilatation with a 2.5x10 mm balloon (Sprinter) and an intravascular ultrasound (IVUS) study ( figures 2 and 3 ), a 4x16 mm polytetrafluoroethylene (PTFE)-covered stent (Graft Master, Jostent) was deployed at 16 bars for 22 s. Since the subsequent angiogram revealed a residual leak into the distal portion of the aneurysm ( figure 4 ), another 3.5x15 mm PTFE-covered stent (Prograft) was deployed distally in an overlapping fashion at 16 bars for 20 s. Postdilatation was done using a 4x9 mm non-compliant balloon (NC Sprinter).
