A 51-year-old woman with pulmonary arterial hypertension presented with progressive chest pain and dyspnea. Computed tomography imaging showed significant enlargement of her main pulmonary artery (PA) and was suggestive of left main coronary artery (LMCA) compression by the PA. The patient underwent percutaneous coronary intervention, which confirmed the diagnosis and a stent was deployed to the LMCA. Three months after the procedure the patient has near resolution of her symptoms. LMCA compression by an enlarged PA is an important cause of chest pain in patients with pulmonary arterial hypertension and can be managed safely and effectively with percutaneous coronary intervention and stenting.
一名51岁的肺动脉高压女性患者出现进行性胸痛和呼吸困难。计算机断层扫描成像显示其主肺动脉（PA）明显增粗，提示PA压迫左冠状动脉主干（LMCA）。患者接受了经皮冠状动脉介入治疗，确诊后在LMCA置入了支架。术后三个月，患者症状几乎完全缓解。PA增粗压迫LMCA是肺动脉高压患者胸痛的重要原因，经皮冠状动脉介入治疗和支架置入可安全有效地对其进行处理。
