PCI to distal SVG to OM-2003 PCI to distal SVG -LAD-2004 PCI t di t l SVG OM 2007 PCI to distal SVG-OM-2007 Re-look CAG (5/7/2010) revealed Native TVD with Occluded SVG-RCA. SVG-

Re-look CAG (12/09/2011) showed patent all previous stents both graft vessel but significant lesion in anastomotic site SVG to OM.

Discussion Progressive closure of SVG graft
‐ 10‐12% in 1st year, 3‐5% per yr,50‐60% by 10 years SVG intervention is an attractive therapeutic alternative to re‐operation.

Discussion Intra‐coronary vasodilators ( diltiazem, varapamil, nicardipine) or adenocine and nitro‐ prusside, help f i d i fl h from preventing and treating no re‐flow phenomenon but there is no evidence that they protect MI.

SVG lesion is more lipid rich ,softer and prone to p , prupture. May lead to an enhanced inflammatory and thrombotic reaction after stent deployment.
Although most patients with recurrent angina due SVG stenosis can be manage medically, catheterization should b f d h li i f i h i be performed at the earliest signs of recurrent ischemia to detect critical graft lesions that can be treated before the irreversible loss of the graftthe irreversible loss of the graft.DES in SVG PCI is safe and is not associated with excess mortality rate compared with BMSmortality rate compared with BMSMembrane cover stent(PTFE), Drug balloon(DEB) may b lt ti ti t h bl ffi d be alternative option to have comparable efficacy and improved long term safety in DES era.

Use of embolic protection device( distal filter, proximal/ distal occlusion‐aspiration device) in suitable lesion,p ) ,
direct stenting and avoiding stent over e pansion/ post dilatation decreases the expansion/ post dilatation ‐decreases the risk of distal embolization thereby improved short‐term procedural safety and mortality; however long term results y; gare not still similar to those of native vessels PCI.vessels PCI.
Conclusion
* Repeated PCI successfully done in this patient asN i l diff l di d d ‐ Native vessels are diffusely diseased and totally occluded from ostio proximal segment i l PCI ’ d iso native vessel PCI wasn’t good option
‐ Re‐do CABG was refused by the patient( reop. Doned LIMA h i fi CABG) due to LIMA crash in first CABG)
* No short & long term difference in BMS Vs. DES •Distal protection device was helpful to prevent NO re‐flow phenomenon.p
