Coronary Artery Bypass Grafting in a Patient With Situs Inversus Totalis

Abstract

Situs inversus totalis (SIT) describes a complete mirror image of the visceral organs in the thoracic and abdominal cavities. Dextrocardia, in combination with SIT, is a rare congenital anomaly with a frequency of 1:10 000, and coronary heart disease may occur with a similar frequency and manifestation as in the general population. Coronary computed tomogra-phy (CT) angiography is useful for accurately assessing the coronary artery origin and position for preprocedural plan-ning of difficult coronary artery catheterisation in SIT. In this case, invasive coronary angiography (ICA) was performed from the same angle but on the opposite side compared to standard angiography. With the use of volume-rendered three-dimensional and curved reformatted images recon-structed from coronary CT angiography, the advancement of guidewires and catheters during ICA as well as the planning of surgical procedures can be performed more safely.
