Standard Conduits Used in Coronary Artery Revascularisation, an Immediate and Midterm Patency Comparative Study in the Population of Largest City of Uttar Pradesh, A Single Centre Study

Introduction: Coronary artery revascularisation is a mainstay technique to alleviate the morbidity of coronary artery disease. There are various conduits available for coronary bypass grafting, we hereby study the conduits routinely used for revascularisation and compare the results. Material and methods: In study 56 people were included, who visited the OPD, were in the IPD, or had come for follow up in OPD over a period of 1 year .Patient included in the study were cases of coronary artery disease in which CABG was a class I indication. A total of 215 conduits were grafted , which included left internal mammary artery graft, reversed saphenous vein graft, radial artery grafts and patients were evaluated for graft patency over a period of 1 year at intervals of 1 month and 1 year . Results: There were 56 LIMA grafts used, 150 RSVG and 9 RA grafts grafted. During follow up period the data was divided into graft failures (defined as total occlusion of the graft), graft failures that took place within 1 months of grafting were termed as early graft failure and graft failures that took place after 1 year were termed as intermediate graft failure. Out of 215 conduits that were grafted a total of 26 conduits were considered as graft failures over a period of 1 year. Conclusion: Reversed saphenous grafts had a greater graft occlusion rate in comparison to internal mammary graft and were better suited for non- LAD site for grafting and thus routinely practiced. Radial artery theoretically seemed to be a better option than RSVG but in our study the data was insufficient to come to a conclusion.
