axial view at initial diagnosis of pseudoaneurysm. (A) Right main
coronary ostium, (B) Left main coronary ostium, (C) Pseudoaneurysm with
contrast extravasation (arrow), (D) Pseudoaneurysm in largest dimension
arising from the left ventricular outflow tract (LVOT) (arrow).
Figure 2 – CTA, axial images, demonstrating interval growth of
pseudoaneurysm. (A) Right main coronary ostium, (B) Left main coronary
ostium, (C) Pseudoaneurysm with contrast extravasation (arrow), (D)
Pseudoaneurysm in largest dimension arising from the left ventricular
outflow tract LVOT (arrow).
Figure 3 – Left heart catheterization via transseptal puncture
revealing contrast extravasation from the LVOT proximal to the
replacement aortic valve.
Figure 4 – CTA, axial images, demonstrating resolution of
previously documented pseudoaneurysm. (A) Right main coronary ostium,
(B) Left main coronary ostium, (C) Thrombosed pseudoaneurysm sac, (D)
Thrombosed pseudoaneurysm with no contrast extravasation from the LVOT.
