Abstract
Case Presentation: A 61-year-old man with the history of stenting in the Right Coronary Artery (RCA) presented with acute inferior ST Elevation Myocardial Infarction (STEMI). Emergent coronary angiography revealed the acute instent thrombotic occlusion of the RCA. After wiring, predilatation of the previous stent was carried out. Test injection showed Ellis type III coronary perforation. A 3.5*15 mm balloon was inserted promptly and was inflated at the perforation site. Right femoral artery access was obtained and a stent graft was deployed using the double guide catheter or the ping pong technique. The perforation was sealed and extravasation was ceased. Echocardiography showed moderate pericardial effusion without any sign of chamber collapse. Heparin was not reversed in order to prevent stent thrombosis. Further echocardiography 3, 24, and 48 hours after the procedure showed the noticeable reduction of the pericardial fluid and the patient was discharged home in favorable conditions. He participated in regular follow-up visits and did well after about 18 months.
Conclusion: The double guide catheter technique was found to be a safe and effective method in treating Ellis type III coronary perforation.
