Abstract: | Arteria lusoria is the most common anomaly of the aortic arch with an incidence of 0.5%–2.5%. It is mostly diagnosed incidentally while performing imaging for evaluation of other unrelated medical conditions. The aberrant right subclavian artery arises beyond the origin of the left subclavian artery from the aortic arch. This results in a complex right‐subclavian‐aortic anatomy which leads to difficulty in transradial coronary angiography. This can lead to prolonged procedure time and increased use of catheters by unaware interventionists. This is even more important if this is encountered in the setting of an acute myocardial infarction. Our review takes into account clinical significance of this uncommon anomaly in the field of interventional cardiology. |
