Coronary Angiography and Chronic Total Occlusion Angioplasty in a Patient With Situs Inversus from the Right Radial Approach.

We present the case of a patient with known situs inversus referred for cardiac catheterization, which revealed a chronic total occlusion of the right coronary artery. Situs inversus, a rare congenital abnormality, is a term used to describe the inverted position of the chest and abdominal organs. Cardiac catheterization is rare in patients with this particular abnormality. It is important to customize techniques to engage coronary arteries and optimize guide support if percutaneous coronary intervention is required in these particular cases.
