Double right coronary artery and its clinical significance: Review of the literature

Double Right Coronary Artery from Single Ostia

“…We reported a case of double RCA from a single ostium in a 68-year-old male as an incidental finding in CAG. In previous studies, it has been reported to be predominant in male patients (9)(10)(11). In our case, the CAG findings besides the coronary anomaly were normal; thus, it is possible that the patient's dyspnea was due to the underlying chronic obstructive pulmonary disease and cor pulmonale.…”

“…Patients with double RCA have a high prevalence of atherosclerotic coronary artery disease (CAD). These patients have an increased risk of unsuspected complications of atherosclerotic CAD (10,11). These patients can also show a positive stress test while having no significant stenosis.…”

“…These patients can also show a positive stress test while having no significant stenosis. Three different modalities can be used to diagnosis double RCA, including conventional angiography as the gold standard, multi-detector computed tomography, and coronary magnetic resonance angiography (CMRA); using the first two modalities, patients are exposed to ionizing radiation, whereas CMRA is a safe and non-invasive method (11).…”

“…Although in the literature, the most reported cases of RCA have been from Turkey, there is no defined correlation between ethnicity and its prevalence (11).…”

Double right coronary artery diagnosed by computed tomographic angiography: A case report and systematic review of the literature

“…Overall, in 25% (16/64) of patients, the double RCA was accompanied by myocardial infarction. In addition to atherosclerotic involvement, hemodynamic changes due to ostial narrowing, such as slit-like take off, have been considered as a possible mechanism of myocardial ischemia [9 , 10] .…”
