Based on the clinical and imaging findings, what is the pathology?
Anomalous septal branch arising from LMCA
Spontaneous coronary artery dissection (SCAD) with intramural hematoma and superadded thrombus
coronary perforation with extravasation of dye
Correct! The correct answer is "Spontaneous coronary artery dissection (SCAD) with intramural hematoma and superadded thrombus".
 
Coronary angiography demonstrated contrast extravasation into the subintimal space with narrowing of the true lumen of the left main coronary artery, creating the appearance of a pseudo-branch arising from the LMCA.Intravascular ultrasound (IVUS) confirmed a subintimal hematoma with superadded thrombus.

 
Good try! The correct answer is "Spontaneous coronary artery dissection (SCAD) with intramural hematoma and superadded thrombus".
