TAVR protocol computed tomography (CT) scans demonstrated no significant aortic annular calcification; however, the presence of a calcified nodule can be seen in the annulus shown in the left panel, which is extending into the LVOT shown in long axis view in the right panel indicated by the yellow arrow. . LVOT: left ventricular outflow tract; TAVR: transcatheter aortic valve replacement

FIG1
TAVR protocol computed tomography (CT) scans demonstrated no significant aortic annular calcification; however, the presence of a calcified nodule could be seen in the annulus shown in Figure 1 (left panel), which extended into the LVOT shown in the long axis view in Figure 1 (right panel), indicated by the yellow arrow.
The size of the virtual valve on pre-procedural imaging was measured to be 26 mm.. LCA: left coronary artery; RCA: right coronary artery

FIG2
Aortography demonstrates active annular rupture (yellow arrow) in the panel on the left. The calcified nodule in the LVOT (curved yellow arrow) shown in the right panel, is the cause of annular rupture after the deployment of the 26 mm aortic valve.. LVOT: left ventricular outflow tract; LAA: left atrial appendage

FIG3
Following the valve deployment, a repeat aortography demonstrated normal left coronary artery (LCA) and right coronary artery (RCA) perfusions; however, the annular rupture was also noted (Figure 3, left panel), originating from LVOT where the calcified nodule was located Figure 3, right panel).
