64-slice MDCT coronary angiography is an effective non-invasive imaging modality for documenting left main coronary artery compression by a dilated pulmonary trunk in patients with pulmonary hypertension.
MDCT may document left main compression by dilated pulmonary trunk in pulmonary hypertension; leaves open impact on management or outcomes.
Compression of left main coronary artery (LMCA) secondary to pulmonary trunk dilatation is a newly recognized entity that has been associated with severe pulmonary hypertension. In this paper we present a case of extrinsic compression of LMCA caused by dilated pulmonary trunk secondary to pulmonary hypertension documented using 64-slice multidetector computed tomography (MDCT) coronary angiography. This case is followed by a review of the literature.
