Emergency off-pump complete arterial revascularization in a patient with dextrocardia.

We describe complete emergency arterial coronary artery bypass grafting performed on the beating heart of a 73-year-old man with situs inversus totalis and triple-vessel disease. The right internal mammary artery was anastomosed to the left anterior descending artery in situ. The first and second obtuse marginal branches of the circumflex coronary and the posterior descending branch of the right coronary artery were sequentially revascularized using the left internal mammary and radial arteries in situ. The only abnormality was that the position of the heart mirrored that of a normal heart. Beating heart surgery appears to be as safe in patients with dextrocardia as in the general population. However, the position of the surgeon must be reconsidered for optimal handling of stabilizers and to facilitate access to anastomosis sites. Understanding mirror-image coronary arterial anatomy is important for successful surgical outcomes among patients with dextrocardia.
