Background: During coronary artery bypass grafting (CABG), the treatment of coronary artery disease by grafting saphenous vein is a common practice. However, within 10 years of SVG intervention due to degeneration and occlusion of grafted artery, the failure rate of SVG is observed to be as high as 50%. The repeat vascularisation with PCI has increased in clinical practice; however, the data on clinical outcome in Indian population is limited.

Methods: A retrospective observational analysis of 30 post-CABG patients with SVG-PCI in single centre between April 2010 and July 2020 was conducted.

Results: The average age of patient was 62.7 ± 9.9 years and majority were male patients (87%) with history of diabetes mellitus (63%), hypertension (73%) and habit of tobacco (83%). After 11.0 ± 4.1 years of CABG with an average of 2 SVGs, the PCI of SVG to OM vessel was performed with drug eluting stents in 97% of cases. PCI of native vessel was performed in only 30% of cases. In majority of SVG-PCI cases (63%) one stent with an average length of 23.2 ± 7.3 mm and diameter of 3.5 ± 0.50 mm was implanted. Patients were discharged on DAPT regimen and in 80% DPDs were used on a routine basis. At 1 year follow-up, 97% of cases had no complications during follow-up, but one case had undergone redo CABG.

Conclusion: The PCI of SVG lesions had positive clinical outcomes as revealed by fewer incidences of post procedural and post-discharge complications.
