Anomalous coronary arteries are relatively common, occurring in approximately 1.3% of the general population. Most variants of anomalous coronary arteries do not cause disability and have a benign course. Surgery is warranted to alleviate symptoms. However, some anomalies, such as a left coronary artery arising from the right sinus of Valsalva and passing between the great vessels or anomalous left coronary artery arising from the pulmonary artery, are considered malignant as they have been associated with sudden cardiac death or heart failure, and in these cases, surgery is indicated. Coronary artery fistulas are abnormal communications between a coronary artery and another cardiovascular structure. They are relatively rare, and surgical or transcatheter closure may be necessary in patients with large left-to-right shunts and/or regional myocardial ischaemia.

Anomalous coronary arteries are rare and often incidental findings. Most variants are benign. We present the case of a 75-year-old man with exertional dyspnea in whom the left anterior descending coronary artery arose from the right sinus of Valsalva, and the left circumflex coronary artery originated from the distal right coronary artery and supplied the obtuse marginal branch. No arteries originated from the left sinus of Valsalva. The patient was prescribed optimal medical therapy for atherosclerotic stenosis in his ramus intermedius. His symptoms were stable 3 years later.

Anomalies of the coronary artery are uncommon, with a reported incidence of 0.3% to 1.3% in the coronary angiography studies routinely performed for suspected atherosclerotic coronary disease. There were 0.92% incidence of anomalous origination of the right coronary artery from the left sinus and the 0.15% incidence of anomalous origination of the left coronary artery from the right sinus. Most coronary artery anomalies are diagnosed by invasive angiography performed to investigate suspected atherosclerotic coronary disease. There are two important managements for patient with anomaly coronary artery. First, these coronary anomalies should result in exclusion from participation in intense competitive sports to reduce the risk of a cardiac event or sudden death. Second, and more importantly, treatment for wrong sinus coronary artery anomalies are revascularization can be either surgical or percutaneous. Surgical intervention should be considered for high-risk varieties of anomalous coronary arteries, as this is the only treatment that has been demonstrated to improve coronary blood flow and carries a low morbidity and mortality.

Herein, we present a brief case of anomalous coronary arteries mistaken to be chronic total occlusion. Since we first presumed the anomalous coronary arteries to be chronic total occlusion of the distal right coronary artery, percutaneous coronary intervention was attempted for the presumed lesion, but it failed. Before the second attempt of percutaneous coronary intervention, coronary computed tomography angiography revealed the coronary artery from the left anterior descending artery corresponding with the distal part of the right coronary artery without connection to the right coronary artery. Therefore, we recognized the patient had anomalous coronary arteries with no connection of the vascular wall between the main and distal segments of the right coronary artery. This case may give insights to the importance of meticulous examination of coronary computed tomography angiography imaging before chronic total occlusion percutaneous coronary intervention to avoid the unnecessary procedure.

Abstract Background In literature, anomalous coronary arteries from the opposite sinus of Valsalva or opposite coronary artery (ACAOS) are reported between 2% to 39% of patients with Tetralogy of Fallot (TOF). Knowledge of coronary anatomy prior to corrective surgery is vital to avoid damage to vessels crossing the right ventricular outflow tract (RVOT). The current range of reported prevalences is broad and a general overview comparing current knowledge on anomalous coronary arteries in TOF is lacking to date. Purpose In this meta-analysis, we aim to provide a detailed overview of current knowledge on prevalence of coronary anomalies in TOF and discuss the implications for patient management. Methods PubMed, Embase and Web of Science were searched for articles on TOF and coronary anomalies. Analysis was done using Revman 5.3 (Cochrane Community, London). The primary analysis focused on the origin and proximal course of the right and left coronary arteries. Also, the prevalences of large conus arteries and coronary arteriovenous fistulas were calculated. Results Twenty-nine studies, comprising 6977 patients all together, were included for primary meta-analysis of ACAOS. 6% of TOF patients have an ACAOS. Of these anomalous vessels, 72% crosses the RVOT. 6% of patients have a large conus artery and 4% a coronary arteriovenous fistula. Other incidentally reported coronary anomalies in TOF include a left or right coronary artery originating from the pulmonary artery, an accessory left anterior descending artery, hypoplasia of the entire coronary tree and anastomoses between coronary and bronchial arteries. CT-angiography is the imaging modality of preference because of its high spatial resolution. Transthoracic echocardiography can be used in younger children as well for discerning the coronary anatomy. Most surgical approaches can be adapted to an anomalous coronary artery coursing over the RVOT. Overall prevalence of ACAOS in TOF Conclusions Coronary anomalies have a high prevalence in TOF. An ACAOS occurs in 6%, large conus arteries exist in 6% and coronary arteriovenous fistulas in 4% of cases. A substantial part crosses the RVOT. This has to be taken into account during surgery.

AbstractA 16-year-old patient underwent successful ablation of ventricular arrhythmia originating from the aortic sinus of Valsalva following surgical unroofing of an anomalous right coronary artery. This case illustrates the complexity of decision making in the management of patients with anomalous coronary arteries and the importance of keeping an open mind when determining ventricular arrhythmia aetiology and origin.

Morphometric analysis of the structures of the aortic bulb and coronary arteries is necessary for the planning of cardiac surgery and endovascular interventions. The aim of the study was to determine the height of the coronary arteries branching in healthy women of Lviv city and Lviv region and to determine the relationship between the height of the location of the orifice of the coronary artery with anthropometric indicators. Fifteen computed tomography images with contrast of female thorax without heart and ascending aortic lesions (normal) were selected for the study. The height of the upper and lower edges of the coronary arteries was measured; height of Valsalva sinuses. The comparison of the mean values was performed according to the Student’s t-test. The correlation between the observed variables (age, height, body weight, body mass index, body surface area, height of the sinuses of Valsalva) was calculated using the Pearson linear correlation method (r). According to the study, the population group consisted of persons of the second period of adulthood (46.67 %) and the elderly (53.33 %). According to the body mass index, 80 % were overweight or obese I-II degree. The mean height of the coronary artery orifice in women without structural changes of the heart and ascending aorta was: 11.19±1.96 mm for the left and 11.68±1.80 mm for the right. The height of the orifice of the right and left coronary arteries were almost the same, without statistical significance (p=0.26). Analysis of the correlation between the values of the height of the orifice of the coronary artery did not show a probable dependence on height, weight, age, body mass index and body surface area. There is a direct relationship between the parameters of the height of the lower edge of the right coronary artery and the height of the upper edge of the right coronary artery (r=+0.75, p=0.001) and between the value of the lower edge of the left coronary artery and the upper edge of the left coronary artery (r=+0.63, p=0.01). Thus, the analysis of the correlation between the values of the height of the orifice of the coronary artery in women in norm and anthropometric indicators did not show a significant relationship. There was no statistical significance between the indicators of the height of the orifice of the right and left coronary arteries in women.

Coronary artery variations are one of the commonest variations observed during clinical procedures. Normally, there are two main coronary arteries, the right coronary artery (RCA), left coronary artery (LCA).Left coronary artery gives two important branches left circumex artery (LCX) and left anterior descending (LAD) arteries. Knowledge about the coronary vessels and its variations are essential to clinicians to prevent untoward injury of vessels during any procedures. To study the morphology and variations of coronar Aim: y arteries by dissection. Materials and Methods: The present study was a cadaveric study which was conducted on 50 hearts obtained from adult human cadavers. Coronary arteries were dissected to see the origin, course and variations. The data was entered in Microsoft excel sheet and expressed in percentage. The Right Results: coronary artery branched out from the right aortic sinus and had an average diameter of 3.5mm. The left coronary artery arouse from left aortic sinus and had an average diameter of 4mm. LMCA divided into two branches in 60 percent, three branches in 30 percent and four branches in 06 percent of the hearts and direct branches from left aortic sinuus in 4 percent hearts.Based on the origin of Posterior descending or interventricular artery, Right dominance was observed in 68 percent, left dominance in 26 percent, and equal dominance in 06 percent of the hearts. Conclusion: Knowledge about the variations of coronary vessels is a prerequisite for clinicians to perform interventions of coronary vessels.
