BACKGROUND: The incidence of coronary artery disease in patients with dextrocardia associated with situs inversus is similar to that of the general population: Nevertheless, there are few papers regarding surgical myocardial revascularization in these patients.

METHODS: We report two patients with dextrocardia and situs inversus who underwent myocardial revascularization by means of coronary artery bypass grafting, with the right internal mammary artery to the left anterior descending coronary artery in one case and with the left internal mammary artery as a free graft to the left anterior descending coronary artery associated with the repair of an aneurysm of the right coronary sinus of Valsalva in the second patient.

RESULTS: There were no surgical complications; the patients were discharged on the 4th and 7th postoperative days, respectively. They are alive and well after 24 and 60 months of follow-up respectively.

CONCLUSIONS: This report suggests that durable myocardial revascularization in dextrocardia with situs inversus can be successfully achieved with right or left mammary artery bypass grafting to the left anterior descending coronary artery. The advantage of using an in situ mammary artery is discussed.
