Clinical Information

Relevant Clinical History and Physical Exam

 This is a 61 years old man who had past medial history as CAD with AMI s/p emergent CAB-G surgery in 2005 with graft 1st vessel to LAD and graft 2nd vein vessel to LCX-OM1 and RCA-PDA. This time, he suffered from suddenly onset chest pain , and visited to our ER where inferior wall STEMI was noted by ECG. Emergent CAG was arranged showed the  2nd vein graft for RCA-PDA part with stenosis and thrombus formation. With failed imrop9ved symtpoms by graft tretmetn,We decide to open the native RCA

Relevant Test Results Prior to Catheterization

  Initially we tried to manage the vein graft as aspiration technique and IC Aggrastat injection and balloon dilation. However, the result was not ideal even the flow was appeared. After several trying to improved the vein graft flow but in failed. Patient's angina was still persisted. So we decided to open the native RCA (as chronic total occlusion) that time!

Relevant Catheterization Findings

 We had tried retrograde and antegrade procedure for the RCA CTO and finally we successful make revascularization of RCA. After stenting, the RCA was coming back as new one It's brave to make the decision to manage the native CTO vessel instead of keeping thrombotic agent injection for the distal vein graft thrombus problems. And fortunately, we overcame the problems and succeed rescue the native CTO vessel for STEMI problems
