Extrinsic compression of the left main coronary artery (LMCA) can occur in patients with an enlarged pulmonary artery trunk secondary to severe pulmonary hypertension (PH). This phenomenon rarely occurs in PH; moreover, few reports have shown that chronic thromboembolic PH can be a triggering factor for this syndrome. Herein, we describe a patient with extrinsic compression of the LMCA with chronic thromboembolic PH who underwent pulmonary endarterectomy and coronary artery bypass grafting successfully. Intravenous ultrasonography (IVUS) was effective for detecting and assessing the compression.
继发于严重肺动脉高压（PH）的肺动脉主干扩大患者可出现左主冠状动脉（LMCA）的外在压迫。这种现象在PH中很少见；此外，很少有报告表明慢性血栓栓塞性PH可能是该综合征的触发因素。在此，我们描述了一名患有慢性血栓栓塞性PH且LMCA受到外在压迫的患者，该患者成功接受了肺动脉内膜切除术和冠状动脉旁路移植术。静脉内超声检查（IVUS）对于检测和评估压迫有效。
