ABSTRACT: Background: Pulmonary artery aneurysm
(PAA) is an unusual finding and its association with left main coronary
(LMCA) compression is even more infrequent. Cardiac CT evaluates
of presence and size of PAA and the degree of LMCA compression. The aim of this
study is to describe two cases of adults with compression of LMCA with PAA
associated with PDA and pulmonary hypertension. Case presentation: The first case is a 27-year-old man
with PAA (78 mm diameter) and LMCA compression of 70% between the aortic sinus
and the PAA. He presented angina as a manifestation of the LMCA compression.
During follow-up the patient died. The second case is a 28-year-old man with
PAA (110 mm diameter) that compresses LMCA in 55%, he rejected surgical
treatment, but he is in close follow-up with medical treatment. Conclusion: Cardiac
computed tomography played an important role both in the diagnosis and
identification of high-risk PAA patients.
