Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The objectives of the study are two-fold: 1. To determine the mean 5 year patency rate of the radial artery graft (Open vs. Endoscopic) of patients who have already had CABG surgery and who previously participated in the centre's RCT back in 2005-2007 using CTA and MPS-MIBI 2. To determine patient quality of life at 5 years post CABG surgery It is hypothesized that the mean 5 year patency rate of the radial artery graft harvested endoscopically will be equal to or have greater patency than the radial artery graft harvested via the conventional/open technique. It is further hypothesized that patient quality of life will be similar amongst patients having had the open vs. endoscopic radial artery graft during CABG surgery.
