Off-pump Y-graft coronary artery bypass in a patient with situs inversus totalis

Abstract

Situs inversus is the mirror image of situs solitus. Situs inversus with dextrocardia is termed 'situs inversus totalis'. Since situs inversus totalis is a rare condition, there are a only a few reports about off-pump coronary artery bypass (OPCAB) in these patients. A 67-year-old man with a diagnosis of situs inversus totalis and three-vessel disease, underwent an elective surgical revascularization. The operation consisted of an OPCAB using a total arterial composite Y-graft. The right internal mammary artery (RIMA) and the left radial artery (RA) were harvested as pedicles and they were anastomized as Y-grafts. Three distal anastomoses were performed: the RIMA to the anterior descending artery and the RA sequentially to the obtuse marginal branch and the posterior descending artery. The peculiarity of OPCAB no-touch with a composite graft in a patient with situs inversus totalis consisted in the mirroring of the whole surgical set-up and of the surgical strategy. The surgery as well as the postoperative period were uneventful. This case report shows the feasibility of OPCAB 'no-touch' with composite arterial grafting in a patient with situs inversus totalis.
