AbstractAnomalous origin of the right coronary artery from the opposite sinus (right-ACAOS) with interarterial course (IAC) has been associated with increased risk of sudden cardiac death (SCD). Widespread use of coronary computed tomography angiography (CCTA) has led to increased recognition of this condition, even among healthy individuals. Our study sought to examine the prevalence, anatomical characteristics, and outcomes of right-ACAOS with IAC in patients undergoing CCTA for suspected coronary artery disease (CAD). We conducted a retrospective analysis of consecutive patients referred for CCTA at one tertiary hospital from January 2012 to December 2020. Patients exhibiting right-ACAOS with IAC were analyzed for cardiac symptoms and mid-term occurrence of first MACE (cardiac death, SCD, non-fatal myocardial infarction (MI) or revascularization of the anomalous vessel). CCTAs were reviewed for anatomical high-risk features and concomitant CAD. Among 10,928 patients referred for CCTA, 28 patients with right-ACAOS with IAC were identified. Mean age was 55 ± 17 years, 64% were male and 11 (39.3%) presented stable cardiac symptoms. Most patients had at least one high risk anatomical feature. During follow-up, there were no cardiac deaths or aborted SCD episodes and only 1 patient underwent surgical revascularization of the anomalous vessel. Right-ACAOS with IAC is an uncommon finding (prevalence of 0.26%). In a contemporary population of predominantly asymptomatic patients who survived this condition well into adulthood, most patients were managed conservatively with a low event rate. Additional studies are needed to support medical follow-up as the preferred option in this setting.

AbstractMyocarditis and coronary artery anomalies are both potentially life-threatening aetiologies of cardiac chest pain in children. We present a case of a young man presenting with non-exertional chest pain and subsequently found to have an anomalous origin of the right coronary artery from the left coronary sinus with an interarterial course in addition to a diagnosis of myocarditis. The patient subsequently was able to undergo surgical correction of his anomalous coronary to mitigate the risk of sudden cardiac death.

Abstract In 68% of cases, the left coronary ostium is at the free edge of the left sigmoid valve in 22% of cases over the edge of the valve and in 8% of cases under the free edge of the valve. In 56% of cases, the right coronary ostium is at the free edge of the left sigmoid valve in 28% of cases over the edge of the valve and in 16% of cases under the free edge of the valve. We found 5 cases with two right coronary ostium and 2 cases with two left coronary ostium. We found that in 38% of cases, the left coronary artery ends in three branches, such as anterior interventricular, circumflex and left marginal arteries, in rest of the cases, the left coronary artery ending by two branches like the anterior interventricular and circumflex arteries in which case the marginal artery originate from circumflex artery and rarely from anterior interventricular artery, or both, in this last case the left marginal artery being double. We found only 8 cases in which the circumflex artery ends as posterior interventricular artery in rest of the cases being represented by the right coronary artery end. Circumflex artery ends by two branches quite often and rarely with three branches which can sometimes be long, down to near the apex of the heart. In 8% of cases, the circumflex artery was less developed and do not vascularize other than the left side of the posterior surface of the left ventricle, sometimes his terminal ramus being left marginal artery. The right coronary artery frequently ends on diaphragmatic surface of the heart either as a single branch in posterior interventricular groove, by bifurcation or even rarely by trifurcation, when one or two branches are located in the posterior interventricular groove. Sometimes the right coronary artery ends on the posterior surface of the left ventricle, where the posterior interventricular artery occurs as collateral branch of the right coronary artery, the right coronary artery extending their vascularization territory to the posterior surface of the left ventricle, right up to the apex of the heart, the right coronary dominance, the circumflex artery in this case ending on the lateral surface of the heart. The right coronary artery may end up on the posterior surface of the right ventricle in which case posterior interventricular artery is represented by the terminal portion of the circumflex artery. The right coronary artery rarely ended as the posterior interventricular artery can reach the apex of the heart. We have found that the dominant type of a coronary artery can be held not only in the number of collateral, but also by their caliber at their origin from the aorta. We encountered 7 cases in which there is a third coronary artery, in 5 cases the third coronary artery being an anterior right I called her middle coronary artery or right ventricular branch and anterior ventricular artery, and in two cases the third coronary artery represent the circumflex artery. In 6 cases of the 7 cases described the third coronary artery showed no atrial branches

ABSTRACT Were used twelve (12) adult anteaters (Myrmecophaga tridactyla), adults, 6 (six) males and 6 (six) females, weighing from 20 to 27.32kg from free life. The thoracic cavity was opened until visualization of the whole heart and lungs and later injection of the coronary vessels. The right coronary artery emerged through a single coronary ostium of the aorta, 50%, emitting the intermediate branch and the subsinuous interventricular branch, had a path directed to the subsurface interventricular groove. In the other 50%, the right coronary artery was not present, showing only its branches, intermediate branch and subsurface interventricular branch with emergence of the aorta. Left coronary artery presented, in 83.33%, origin from the aorta in single ostium, issuing the circumflex and interventricular paraconal branches. In 16.66%, the left coronary artery was not evidenced originating from the aorta, but its branches, circumflex and interventricular paraconal.

Coronary artery anomalies are common among patients with tetralogy of Fallot. One hundred and thirty-five patients (80 males and 55 females) with tetralogy of Fallot who underwent repair between 1995 and 2002 were studied to determine the incidence of coronary anomalies in Iranian patients. Eight (5.9%) patients (4 males and 4 females) had a surgically relevant coronary artery anomaly: single coronary ostium in 5, origin of the left anterior descending artery from the right coronary artery in 2, and origin of the right coronary artery from the left coronary artery in 1. The surgical technique in 3 of these patients was repair of the ventricular septal defect with a transverse incision on the right ventricle, without damage to the coronary arteries. In another patient, an allograft aortic valve cylinder was inserted. In the other 4 patients with a single coronary ostium, placement of a limited transannular patch was adequate. Consideration of these anomalies during primary repair could decrease the risk of operation in such patients. However, it seems that the presence of anomalous coronary arteries does not affect incremental risk after surgical repair.

A 17-year-old African-American man was being followed for palpitations and chest pain. CT angiography revealed an anomalous right coronary artery from the left coronary sinus and he underwent unroofing of the right coronary ostium. There was a manifest pre-excitation on postoperative ECGs, and review of prior ECGs at initial presentation showed subtle pre-excitation suggesting a left lateral pathway. An electrophysiology study revealed easily inducible supraventricular tachycardia (SVT) and rapid anterograde conduction via the pathway which was successfully ablated. Eight months postablation, the patient remains asymptomatic with no evidence of pre-excitation on ECG.
