Abstract

Coronary angiographic appearance of ambiguous-looking lesions can be deciphered by the use of optical coherence tomography. An apparent pseudoaneurysm on coronary angiography turned out to be a coronary dissection associated with aneurysm formation.

A 48-year-old male presented to us with recent anterior wall myocardial infarction. Coronary angiography revealed 90% tubular stenosis in the proximal left anterior descending (LAD) with an ambiguous saccular lesion just adjacent to it (outside the boundary of the lumen) and connected to it via a narrow neck [Figure 1]a. Coronary angiographic appearance led to a differential diagnosis of (1) coronary pseudoaneurysm (narrow neck of focal outpouching), (2) coronary dissection (? dissection flap), and (3) coronary aneurysm (focal outpouching but narrow neck against it).{Figure 1}

To characterize the disease, intravascular imaging with optical coherence tomography (OCT) was planned and revealed the culprit lesion as coronary dissection (dissection flap seen) with aneurysm formation (focal outpouching with intact three-layered wall) [Figure 1]b. Following delineation of the pathology of the lesion, LAD stenting followed to focal high-pressure postdilatation of the disease segment was undertaken. The importance of this case lies in the fact that intravascular imaging by OCT can help us differentiate these ambiguous-looking angiographic lesions and plan further management.

Teaching points:

Ambiguous-looking lesions on coronary angiography should undergo intravascular OCT imaging to better delineate the lesion and plan further managementAssociation of coronary dissection and pseudoaneurysm has been reported, but coronary aneurysm associated with dissection is rare and occurs in cases where dissection plane is intraintimal.
