Case Of Double Right Coronary Artery Research Articles

Dual versus split right coronary artery: What is there in the name?

Congenital coronary artery anomalies are rare which are generally detected incidentally during coronary angiograms. Double right coronary artery (RCA) is one such rare coronary anomaly, and various other terms are being used to describe it such as dual RCA or split RCA. However, no final consensus regarding definition of dual or split RCA has been made till now. We reported two different cases of double RCA and proposed to differentiate dual versus split RCA on the basis of their number of ostia from the right sinus of Valsalva. Various reports of increased atherosclerosis particularly in single ostial origin split RCA have been described recently. Their clinical implication lies in the fact that one should have background knowledge of such a rare coronary anomaly particularly during acute coronary syndromes with complete occlusion so that culprit artery could not be missed.

Case of Double Right Coronary Artery: Diagnosed on Computed Tomography Coronary Angiography

Anomalies of the coronary artery are often asymptomatic and uncommon. Double right coronary artery (RCA) is a very rare coronary anomaly. So far, the number of reported cases of double RCA is not many. Nevertheless, there have been several reports of double RCA in the literature, particularly in the last decade. We aim to present a similar case. Multidetector computed tomography (CT) is becoming an alternative method for the diagnosis of coronary artery anomalies. We present the multidetector coronary CT angiography findings from a patient with RCA duplication. Two right coronary arteries originating from two separate ostia of the right aortic sinus were observed.

A Rare Coronary Anomaly: Atypical Double Right Coronary Artery With an Acute Inferior Myocardial Infarction

Coronary artery anomalies are uncommon and often asymptomatic. A double right coronary artery (RCA) is an extremely rare coronary artery anomaly, and only a few cases of double RCA have been reported. We report on an atherosclerotic double RCA that appeared after primary percutaneous intervention in a patient with an acute inferior myocardial infarction. This is the second case in the literature in which coronary arteries can be accepted as a double RCA, which were hidden by a total atherosclerotic occlusion in the proximal part of the RCA.

Response to the Letter to the Editor: “The correct number of double right coronary artery reported in the literature”

We would like to respond to the letter written by Sari et al regarding the correct number of published double right coronary artery (RCA) cases [1]. Our case [2] was presented as the second case who had an RCA with separate orifices according to the letter reported by Harikrishnan et al. in 2001 [3]. The case report entitled “Supernumerary right coronary artery” by Gupta et al was published in 1987 and was cited only by Lemburg et al. in 2007 [4] which was unavailable to us at the moment we have submitted the letter. Unfortunately, we could not see any citation of this article by Gupta et al in any of the previously reported cases about double RCA till October 2006, including the letter by Sari et al. published in 2006 [5]. The 3 cases reported by Kunimasa et al. and Lemburg et al. were published in 2007 [4,6] which were also not available for us to cite, since we have submitted our letter in October 2006. Also we observe conflict of data in the table summarizing the cases by year of publication by Sari et al. [5]. The cases presented by Lemburg and Kunimasa were shown to be published in 2006, whereas the articles were published in 2007 [4,6]. In addition, our case had been submitted in October 2006, whereas it was indexed in the table as 2007 by Sari et al. Although online publications serve for faster spread of knowledge it could not always be possible for the readers to review after full publication. The possibility of cases reported in journals not available to be reviewed globally could also change the real number of published cases of double RCA. We agree with the statement about importance of comprehensive literature search. Another crucial issue is to be objective and unbiased, without any conflicts in presented data. In conclusion double RCA is a rare coronary abnormality and awareness is recommended during coronary angiography.
