It is well known that the left internal mammary artery (LIMA) should be the first conduit of choice. Similarly, especially in patients younger than 70 years, other conduits should be search among arterial grafts such as right internal mammary artery (RIMA) or radial artery (RA). If the RA can be harvested in the meanwhile of LIMA harvesting without time consuming, it is well established that former one has to be grafted only on presence of a good run-off. One of the main criticisms moved to the use of RIMA are linked to technical difficulties in its harvesting it. Edgar Aranda-Michel and coworkers tried to answer to the age-old question is “RIMA has to be used in situ or free-graft?” In a retrospective study on 667 patients (442 had free RIMA and 245 had free RIMA) that were also matched through propensity analysis (202 patients per group), they did not find any differences between the two groups in the major outcomes, including heart failure specific readmissions. This finding is consistent with the literature, hence the take-home message is whatever happens, two mammary is better than one.
