Description
Summary:(A-C) CT angiography image at the level of the aortic root showing shorter left anterior descending (LAD) (white arrow) arising separately from the right coronary sinus (RCS) and longer LAD (white arrowhead) from the left main coronary artery (LMCA). Twelve variants of dual LAD are described in the literature.1 Rather than the variant of the dual LAD, the anatomy of dual LADs should be better described according to the clinical significance and risk stratification for the anomalous aortic origin of a coronary artery (AAOCA) from the inappropriate sinus of Valsalva (SOV).2 In the classification proposed by Cheezum et al, anomalous left coronary artery (ALCA) arising from the right SOV or anomalous right coronary artery arising from the left SOV or rarely, AAOCA from the ‘noncoronary’ SOV can further be classified based on the presence of one of the five course subtypes, that is, interarterial, retroaortic, subpulmonic (intraconal or intraseptal), prepulmonic or retrocardiac.2 The risk of sudden cardiac death is highest for interarterial ALCA. Transseptal course of anomalous left main coronary artery originating from single right coronary orifice presenting as unstable angina.
