The prevalence of coronary artery anomalies with coronary computed tomography

Abstract

In this study, the aim is to investigate the prevalence of various coronary artery anomalies (CAAs), evaluated by 256-detector row coronary computed tomography (CCT), within the Turkish population. Materials and methods:We included 2973 patients who had received CCT. The high take-off right coronary artery (RCA) and left coronary artery (LCA), the RCA arising from the left sinus (LS), the LCA arising from the right sinus (RS), the circumflex artery (CX) arising from the RS, the single coronary ostium originating from the RS, the CX arising from the RCA, and the RCA arising from the pulmonary artery were evaluated.Results: Seventy-nine patients (2.65%) were diagnosed with CAAs. The frequency of high take-off of the RCA, LCA, and both was 0.1%, 0.67%, and 0.06%, respectively. Frequency of separate ostium of the left anterior descending artery and CX was 0.67%. The frequency of RCA originating from the LS, CX originating from the RS, LCA originating from the RS, LCA and RCA originating from the pulmonary artery, and CX originating from the RCA was 0.50%, 0.10%, 0.23%, 0.03%, and 0.20%, respectively. Conclusion:In this study, CCT was demonstrated to be a high-quality imaging modality for the detection of CAAs.

High take-off right coronary artery in a patient with tetralogy of Fallot

“…[1][2][3]13,14 The most common coronary artery anomalies in patients with tetralogy of Fallot have been described as left anterior descending artery arising from right coronary artery, single coronary root origin, large conal branch arising from right coronary artery, and double left anterior descending artery. [2][3][4][5][6][7][8][9][10][11][12][13][14][15] In echocardiographic evaluation of our patient, right coronary artery origin could not be shown in standard sections. Only left coronary artery origin from the left coronary sinus could be demonstrated.…”

Aortic Origin Coronary Artery Anomalies: A Case Series

“…The widespread use of CCTA has yielded further insight into the epidemiological boundaries of CAAs, the prevalence of which appears to be even higher [ 4 ]. CAA has an incidence rate of 2.6-7.9% in an unselected patient population upon CCTA [ 4 , 5 ]. This suggests that the true prevalence of coronary anomalies in the general population may have been underestimated based on ICA.…”

Intra-Atrial Right Coronary Artery and Anomalous Origin of Left Circumflex Artery Found Concurrently

“…Given the aforementioned studies detailing the incidence of CAA, which are summarized in Table 1 [7][8][9][10], these anatomical aberrations are an under-recognized cause of cardiac morbidity and mortality. The risk of sudden cardiac death due to coronary artery anomalies is highly unpredictable and heavily dependent on many factors, most importantly the aberrant anatomy and course of the coronary arteries.…”

“…Given the increasing propensity for noninvasive imaging, such as CCTA, our definitions of an anomaly may change as more abnormalities are found. CCTA was shown to be a high-quality study for diagnosing CAA [ 7 ].…”

“…The clinical course and symptom management remains a mystery in patients with multiple coronary anomalies due to the lack of compiled data on adverse cardiac-related events and overall prognosis. In a single-center retrospective study done to evaluate CAA in Turkish populations, high take-off coronary was the most common anomaly at 0.77% [ 7 ].…”
