Key result
Imaging identifies rare combination of single right coronary artery and dual LAD.
Why the study?
The coexistence of right sided single coronary artery and dual left anterior descending artery is an extremely rare coronary anomaly that requires detailed characterization.
Case Report (n=1)
This case highlights the successful identification and percutaneous management of an extremely rare combination of coronary anomalies: a right-sided single coronary artery with a dual left anterior descending artery.
Recognizing this anomaly may aid procedural planning; extends coronary variant literature but leaves clinical impact open.
An 82-year-old female with history of hyperlipidemia and hypertension presented to the clinic with chief complaint of nonradiating chest tightness accompanied by exertional dyspnea. Cardiac catheterization showed the absence of left coronary system; the entire coronary system originated from the right aortic sinus as a common trunk which then gave off the right coronary artery and the left main coronary artery. Cardiac catheterization demonstrated also another rare coronary anomaly: dual left anterior descending artery. Patient underwent percutaneous coronary intervention and subsequent multidetector computed tomography angiography confirmed the above angiography findings. Patient was subsequently discharged home on double antiplatelet therapy with aspirin and clopidogrel and has been asymptomatic since then.

Barbaryan et al. (2016) conducted a case report in Rare coronary anomalies (right sided single coronary artery with dual left anterior descending artery) (n=1). Percutaneous coronary intervention was evaluated. Cardiac catheterization and computed tomography angiography revealed a rare combination of a right-sided single coronary artery and a dual left anterior descending artery in an 82-year-old female.
