Most patients undergoing coronary artery bypass grafting (CABG) will require long saphenous vein (LSV) harvesting from the leg. This has been reported to be associated with a significant morbidity (leg swelling, pain, infection, bruising, wound discharge) in up to 50% of patients. Endoscopic vein harvesting (EVH) which has been reported to be associated with a reduction in these complications was implemented within the investigators' service in 2012. Although some initial reports of concerns regarding graft patency when the LSV is harvested by EVH, NICE and European Cardiology Society (ESC/EACTS) guidelines 2014 supported the use of the EVH technology. Last year a service evaluation in the investigators' department showed significant cost benefit of EVH as compared to open vein harvest (OVH) in a matched group (50 EVH and 50 OVH patients). The purpose of this study is to evaluate this group further to assess the incidence of MACCE (Major adverse cardiac and cerebrovascular event) and patient's quality of life (QOL) at least 1 year after their surgery. MACCE will be assessed by contacting the patient's GP and/or Cardiologist and QOL questionnaire (SF12v2) will be sent to patients along with a patient information sheet. It is estimated that data collection would be completed within 3 months of start.

Inclusion Criteria:

1. Patient underwent CABG (isolated or combined) during period Jan 2012 to Dec 2013
2. LSV harvested by EVH (Study group)
3. LSV Harvested by OVH matched with EVH group (Control group)

Exclusion Criteria:

1. Patient deceased at time of study start

Fifty patients who underwent EVH (Study group) were part of our service evaluation when EVH was introduced to our practice. These patients were matched with patients undergoing CABG during the same period but where the LSV was harvested by OVH (50 patients, control group).

This service evaluation showed a significant cost benefit when EVH was used in terms of reduction in the inhopsital stay, leg wound pain, leg wound infection and need to attend wound clinic. The current study is an extension of the service evaluation to assess how these patients are doing at least a year after their surgery in terms of MACCE, QOL,return to normal activities and survival
