Coronary artery anomalies (CAAs) are very rare a relatively uncommon, diverse group of congenital disorders of coronary arterial anatomy with a clinical presentations. Though most commonly detected incidentally finding during routine catheter, CT angiograms or at autopsy, these anomalies have generated considerable interest as they constitute the second most common cause of sudden cardiac death in young competitive athletes after hypertrophic cardiomyopathy1. Their prevalence ranges from 0.2% to 1.3% based published series 2-4. The most common coronary artery anomaly is origination of the left circumflex coronary (LCX) artery from the proximal of right coronary artery (RCA) or right sinus of Valsalva. The second is separate origination of the left anterior descending coronary artery (LAD) and LCX artery from the left sinus of Valsalva. Herein, we present five cases that the anomalous RCA arises from the left main coronary artery or the mid of left left anterior descending coronary artery (LAD). These cases are extremely rare. we bring forth them in an attempt to highlight their significance, and make cardiologist to understand what important the anomalies are, and how to diagnosis and treatment these bifurcation lesions of coronary anomalies.

In this work are reported two cases of anomalous aortic origin of a coronary artery (AAOCA), with the left main coronary artery (LMCA) arising at the right sinus of Valsalva in a 77-year-old woman and in a 79-year-old man submitted to angiography after positive ischemic tests. The origin of the LMCA or the left descendant artery (LDA) from the right sinus of Valsalva has a prevalence of 0.2%, the origin of the circumflex artery (CXA) from the right sinus 0.5%, and the origin of the right coronary artery (RCA) from the left sinus of Valsalva has a prevalence of 0.3%. It is the subgroup of the coronary anomalies that has the greatest potential for clinical repercussions, especially the sudden cardiac death (SCD). We discuss the diagnostic methods and treatment options for this kind of coronary anomaly in symptomatic cases.

Összefoglaló. Bevezetés: Congenitalis coronariaanomáliának tekintik azokat a coronariamorfológiai rendellenességeket, melyek 1%-nál kisebb gyakorisággal fordulnak elő. Többségük nem jár tünettel, olykor azonban okozhatnak mellkasi fájdalmat, eszméletvesztést, és hirtelen halálhoz is vezethetnek. A coronariaanomáliák gyakoriságáról Magyarországon eddig csak invazív koronarográfiás adatok alapján jelent meg közlemény. Célkitűzés: Jelen vizsgálatunkban a coronariák eredési rendellenességeinek gyakoriságát mértük fel intézetünk coronaria-komputertomográfiás angiográfián átesett betegeinél. Módszer: A coronaria-komputertomográfiás vizsgálatra került betegek felvételeinek értékelésekor rögzítettük a coronariaanomália jelenlétét. A vizsgálat indikációja általában mellkasi fájdalom volt. 128 szeletes berendezést használtunk, a vizsgálatok során részben retrospektív, részben prospektív EKG-kapuzást alkalmaztunk. Eredmények: 1751 beteg komputertomográfiás angiográfiás felvételeit elemeztük. A betegek között a férfiak aránya 38,4%, a vizsgálatra kerülők életkorának átlaga pedig 58,07 ± 11,07 év volt. Eredési anomáliát 1,83%-ban találtunk, ezen belül a leggyakoribb volt a körbefutó ág (ramus circumflexus) és az elülső leszálló ág különálló eredése a bal Valsalva-sinusból (1%). A további rendellenességek a következők voltak: a jobb coronaria eredése magasan az aortából (0,34%), ramus circumflexus a jobb sinusból vagy a jobb coronariából (0,34%), jobb coronaria a bal Valsalva-sinusból (0,057%), elülső leszálló ág részben a bal Valsalva-sinusból a circumflexustól külön, részben a jobb coronariából (kettős elülső leszálló ág, 0,057%). Következtetés: Mindössze 0,057%-ban fordult elő potenciálisan tünetet okozó coronariaeredési rendellenesség (a bal sinusból eredő jobb coronaria). A komputertomográfiás angiográfia segítségével a coronariaeredés helye pontosan megállapítható, tisztázható az ér lefutása és ennek során viszonya a környező struktúrákhoz. Orv Hetil. 2020; 161(47): 1995–1999. Summary. Introduction: Congenital coronary artery anomaly is defined as a coronary morphology which occurs in less than 1% of the cases. Usually these anomalies do not result in symptoms but sometimes they can cause chest pain, syncope and sudden death. In Hungary, the prevalence of these abnormalities was published only from data of invasive coronary angiography. Objective: In this study, we evaluated the prevalence of the anomalies of coronary origin in the patients of our institution undergoing coronary computed tomography. Method: While reading the computed tomography angiograms of our patients, we registered the presence of coronary anomalies. In most of the cases, the indication of the coronary computed tomography was chest pain. A scanner with 128 detectors was used, scans were performed partly with prospective, partly with retrospective ECG gating. Results: We assessed 1751 patients. The ratio of males was 38.4%, while the average age of patients 58.07 ± 11.07 years. Anomaly of coronary origin was present in 1.83% of our patients, with the separate origin of left anterior descending and left circumflex artery being the most frequent (1%) among them. Other anomalies were as follows: high take-off of the right coronary artery from the ascending aorta (0.34%), left circumflex arising from the right sinus of Valsalva or from the right coronary (0.34%), right coronary artery from the left sinus of Valsalva (0.057%), left anterior descending arising partly from the left sinus of Valsalva, apart from the left circumflex, partly from the right coronary (dual left anterior descending artery, 0.057%). Conclusion: The prevalence of potentially symptomatic coronary anomalies was only 0.057% in our series (right coronary from the left sinus of Valsalva). The computed tomography angiography can precisely define the origin of the coronary artery, depict its run-off and its relationship to the neighbouring structures.

This is a case report of a 29-year-old, male applicant for life insurance who was discovered to have an absence of the left main coronary artery (LMCA), with the left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX) each arising directly from the left sinus of Valsalva. A brief review of several types of coronary artery anatomic variants will be presented.

Coronary artery anomalies occur either in isolation or in the context of congenital heart defects (CHD). Isolated coronary artery anomalies include anomalies of connection to the pulmonary artery or to the aorta, anomalies of the intrinsic coronary arterial anatomy including anomalous orifices, and anomalies of myocardial/coronary arterial interaction including myocardial bridges and fistulae. Such defects are of major significance in clinical cardiology and cardiac surgery because of their association with myocardial ischaemia and sudden death. Coronary anomalies associated with CHD can result from three types of developmental perturbation: (1) anomalous epicardial course (in congenitally corrected transposition of the great arteries and L-looped ventricles), (2) anomalous communication with a high-pressure ventricular cavity (pulmonary atresia with intact ventricular septum and hypoplastic left heart syndrome), or (3) anomalous connection to the aorta. Outflow tract defects represents 30–40% of CHD, and their main characteristic is great artery defects influencing coronary arterial anatomy.

The congenital anomaly of an intramural left main coronary artery arising in the anatomically correct aortic sinus is very infrequent. Aneurysms involving the sinus of Valsalva rarely arise from the left aortic sinus. We present the clinical features and surgical correction of this rare anomaly along with a short discussion of these congenital malformations.

Sinus of Valsalva aneurysm (SoVA) is an uncommon clinical entity, which is present in roughly 0. 09% of the general population. The cause can either be acquired or congenital. Clinically the SoVA of unruptured status are rarely captured or even diagnosed due to atypical clinical presentations. Here, we present a rare case of exertional angina pectoris and recurrent syncope due to an extrinsically compressed left coronary artery by a giant SoVA in a 50-year-old female patient. This SoVA was successfully repaired by the surgical exclusion and the patient was still doing well after 2 years of follow-up.
