Aortic angiography showed a 3-mm large rupture of the right coronary sinus into the RV outflow, resulting in moderate significant left-to-right shunt (QP/QS 1.6:1) [Figure 2a]. After deployment, aortic root angiogram revealed mild foaming across the device [Figure 2b] without any aortic valve malfunction or right coronary artery compression.
