A 43-year-old woman with World Health Organization group I severe pulmonary hypertension, associated with systemic lupus erythematosus, was referred for cardiac catheterization as part of a lung transplant evaluation. She was also having anginal symptoms during walking. Physical examination was significant for a loud P2 and right ventricular lift. Coronary angiogram revealed a tight ostial left main (LM) stenosis (Fig. 1A). (Online Video 1) thought due to compression by a markedly enlarged pulmonary artery (PA) (Fig.1A and 1B, Online Video 1 and 2). This was confirmed by a coronary 64-slice multidetector computed tomography (Fig. 1C). She underwent successful LM stenting with a 4 × 15-mm bare-metal stent. Since that time, she has had no recurrence of the angina. Follow-up coronary multidetector computed tomography was done at 5 months and confirmed patency of the stent (Fig. 1D). Given the severity of the underlying disease, the patient continues to be evaluated for lung transplant.
