“…This study found an incidence of 4.2% for double or split RCA which corresponded more closely to Angelini et al [6], who documented 1.23%, than Erbagci et al [14], and Kunimasa et al [22], who found 0.01% and 0.07%, respectively. Due to its rarity, the split RCA is more frequently described in case reports (Table 3).…”

“…Nair et al [26] described a double RCA arising from a single coronary ostium where both vessels of the RCA ran parallel in the right atrioventricular groove and crossed the crux of the heart. In 2007, Kunimasa et al [22] described a double RCA arising from a single ostium and supplying blood to the interventricular septum. Both vessels coursed in the interventricular sulcus but did not cross the crux.…”

“…Our literature review indicated that previous studies have not evaluated the effect of the gender on the incidence of split RCA. However, the use of improperly named "double right coronary" as another anomalous form of the RCA instead of split RCA reduces the frequency of split RCA reported in the literature (Kunimasa et al 2007;Lemburg et al 2007). In fact, there are not two RCAs, but only split portions of the inferior interventricular branch of the RCA, with two separate proximal courses.…”

Coronary artery anomalies are rarely encountered in general population. Gender may play a role in the types and incidence of coronary artery anomalies, although the effect of gender is not well established. In the present study, we therefore aimed to investigate the frequency and location of various types of coronary artery anomalies and their correlation with gender. We assessed retrospectively the coronary angiography movies of 7,810 patients (2,214 females and 5,596 males), the method of which is distinct from the earlier studies with angiographic archive records. We defined and classified the coronary artery anomalies according to their origin, course (myocardial bridge), and termination (fistula). The incidence of coronary artery anomalies was 3.35% (262 of 7,810): 130 individuals with anomalous origin (1.66%), 105 individuals with myocardial bridges (1.34%), and 27 with fistulas (0.35%). The frequency of the coronary artery anomalies was significantly higher in the females than the males ( p = 0.001). Of the coronary artery origin anomalies, the circumflex and the left anterior descending artery originating from separate ostia in the left aortic sinus were higher in the females compared to the males (P < 0.001). In contrast, the frequency of myocardial bridges was higher in the males (P = 0.01). No gender difference was detected in fistulas. Thus, gender affects the types of coronary artery anomalies, except for fistulas. The determination of the presence of the coronary artery anomalies during the coronary angiography is critical for the planning of the treatment and for the proper clinical follow-up of patients.

“…To our knowledge, so far double RCA had been reported 18 times and in 20 cases (Table 1) [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Until the times that these letters were sent to the journal double RCA had been reported 15 times and in 17 cases (Table 1) [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Both authors failed to mention about the papers by Gupta et al [4], Kunimasa et al [17] and Lemburg et al [18] in their letters.…”
