Double Right Coronary Artery: Review of Literature
The International Journal of Cardiovascular Imaging, 2006
Anomalies of the coronary artery are often asymptomatic and uncommon. We report an extremely rare coronary artery anomaly, a double right coronary artery. A 50-year-old male patient was hospitalized with the diagnosis of unstable angina pectoris. Right coronary artery (RCA) injection showed filling of two separately originating RCAs, coursing towards the right atrio-ventricular groove. Then they give a marginal branch and a septal artery, terminated by giving off the posterior descending artery (PDA) in posterior interventricular groove. Coronary anomalies should be recognized to avoid problems during coronary intervention and cardiac surgery.
Double right coronary artery: Report of two cases and review of the literature
International Journal of Cardiology, 2008
Double right coronary artery (RCA) is a very rare coronary anomaly. So far, the number of reported cases of double RCA is not so much. Nevertheless, there have been several reports of double RCA in the literature, particularly in the last decade. We aimed to report two cases with double RCA and review the literature in this issue. In brackets, we searched the wordsdouble right coronary arteryin medline (www.ncbi.nlm.nih.gov) and limit the search into the title. According to the results, so far double RCA have been reported 18 times and in 20 cases. Here in this case report and minireview we discussed the characteristics of the previous 20 and the present 2 cases with double RCA.

Double right coronary artery (RCA) is an extremely rare coronary artery anomaly. We here report an atherosclerotic double RCA which appeared after primary percutaneous intervention performed to treat a 34-year-old male presenting with acute inferior myocardial infarction, cardiogenic shock and complete heart block. This is an unusual case as double RCA had been hidden by total atherosclerotic occlusion of the proximal part of the RCA and complete restoration of patency led complete heart block back to normal sinus rhythm.
Case Reports in Cardiology
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.
Isolated single coronary artery with dual right coronary artery distribution
Herz, 2012
We present the case of a 76-year-old patient in whom coronary angiography, performed due to non-ST-segment elevation myocardial infarction, revealed an isolated single coronary (SCA) artery with dual right coronary artery (RCA) distribution. One RCA arose from the mid segment of the left anterior descending (LAD) artery and followed a prepulmonic course to the right, while the other RCA arose as the terminal extension of the left circumflex artery beyond the crux cordis. This is the second reported case of the combination of these two variants of SCA and the first such case in which the LAD-derived RCA originated as a single branch. Furthermore, this is the first report presenting a sinus node artery with origin from an ectopic LAD-connected RCA. The clinical implications of this rare coronary artery pattern are discussed.

Dual right coronary artery (RCA) is a rare coronary anomaly. This anomaly is often undetected and may be totally asymptomatic to presenting as acute coronary syndrome. Here, we present a 41 year old male diabetic and smoker presented with acute onset severe chest pain of 30 minutes duration which was managed as acute coronary syndrome .His urgent coronary angiogram revealed single ostial origin of right coronary artery ( RCA) with total occlusion from proximal segment followed by double right coronary arteries with their respective distal branches.
