(A) CTA showed a hematoma in the basal segment of the interventricular septum in the acute period after LBBP. On non-contrast CTA, a high-density thickening in the interventricular septum was found. Post contrast, no significant change in the enhancement was observed. (B) CTA confirmed the hematoma has resolved at the 1-month follow-up. CTA, computed tomography angiography.
