使用支架移植物補救經皮冠狀動脈介入治療心肌橋產生冠狀動脈破裂病例報告

Stent Graft to Rescue Coronary Rupture During Percutaneous Coronary Intervention for Myocardial Bridge--A Case Report

心肌橋是一種先天性冠狀動脈異常，會在心臟收縮期產生壓迫，雖然心肌橋大部分沒有症狀，但經皮冠狀動脈介入治療，可以緩解症狀。冠狀動脈破裂，是很少發生在經皮冠狀動脈介入治療時。我們在經皮冠狀動脈介入治療心肌橋時，發生冠狀動脈破裂，使用支架移植物，補救左前降支遠端冠狀動脈破裂的病例報告。

Myocardia1 bridge (MB) is a congenital variation of the coronary arteries, and the segment of the coronary artery through the myocardium is compressed during systole. Although it is almost asymptomatic, percutaneous coronary intervention (PCI) may be necessary to relieve the symptoms. Perforation or frank rupture of coronary arteries rarely occurs in patients undergoing percutaneous coronary intervention. We report the coronary rupture in a case with myocardia1 bridge occurring during the performance of percutaneous coronary intervention. We deployed a stent graft to successfully rescue the rupture of the dista1 segment of left anterior descending coronary artery (LAD-D) with myocardia1 bridge (MB).
