Complications related to pulmonary artery stenting include stent migration, jailing of vessels, vessel rupture, and compression of surrounding structures. Compression of the left main coronary artery (LMCA) as a result of stent placement in the right pulmonary artery (RPA) is extremely rare. We present two patients post repair of congenital heart disease who suffered LMCA compression following RPA stenting. The first patient experienced acute coronary insufficiency in the cardiac catheterization laboratory, whereas the second patient had a more chronic course. We also present a third patient who had a CT angiogram that demonstrated a close spatial relationship between the RPA and the LMCA. Based on our previous experiences, we felt that this patient was at significant risk for LMCA compression if the RPA were stented. Coronary compression is rare complication of pulmonary artery stenting but should be considered in cases with history of repaired congenital heart disease.
与肺动脉支架置入相关的并发症包括支架移位、血管被困、血管破裂以及周围结构受压。右肺动脉（RPA）支架置入导致左主冠状动脉（LMCA）受压极为罕见。我们报告了两名先天性心脏病修复术后患者，他们在RPA支架置入后发生了LMCA受压。首例患者在心脏导管室出现急性冠状动脉供血不足，而第二例患者病程更为慢性。我们还报告了第三例患者，其CT血管造影显示RPA与LMCA之间存在密切的空间关系。基于我们之前的经验，我们认为该患者如果进行RPA支架置入，发生LMCA受压的风险很高。冠状动脉受压是肺动脉支架置入的罕见并发症，但在有先天性心脏病修复史的病例中应予以考虑。
