Abstract:
We report a case with a large aneurysm of right coronary artery (RCA) associated with coronary artery disease. The aneurysm was sealed with two PTFE-covered stents using a sequential technique from proximal to distal to overcome the lack of long PTFE-covered stents and existence of complex coronary anatomy. A bare metal stent was subsequently deployed to treat a lesion in the mid part of RCA. At 4-month follow-up, aneurysm was completely sealed and no restenosis occurred. Usage of sequential PTFE-covered stents enables treatment of large coronary artery aneurysms.
