Background: Coronary Artery Anomalies (CAAs) presenting in adulthood are rare and associated with adverse cardiac events, including sudden cardiac death. Coronary artery anomaly is the second most common cause of Sudden Cardiac Death (SCD) in young athletes. Cardiac Computed Tomographic Angiography (CTA) is a readily available non-invasive imaging modality that provides high-resolution anatomical information of the coronary arteries. Multi-detector row CT is superior to conventional angiography in defining the ostial origin and proximal path of anomalous coronary branches.Methods: This was a prospective study included 186 patients who underwent coronary CTA from December 2018 to November 2019 in Government medical College, Srinagar on a 256 slice CT. The indications for coronary CTA were an equivocal, or non-diagnostic stress test, atypical chest pain, suspected anomalous coronary, as well as the evaluation of cardiac cause of syncope.Results: Ramus intermedius was the most common anatomical variant seen in 25 patients (13.4%). The prevalence of coronary anomalies in this study was 5.66% including myocarding bridging. The most common anomaly was high take off of coronary artery from sinotubular junction accounting for 1.6%.Conclusions: Coronary Computed Tomographic angiography is much superior in detecting coronary artery anomalies than invasive coronary angiography because of the absence of soft tissue information like as is needed in myocardial bridging. Proper knowledge of the anomalies and their clinical significance is highly important in planning treatment and easing hardships of cardiologists in dealing with them.

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.

Purpose.Until the mid-20th century they could be discovered only during autopsy, it means after death. With the introduction of coronary angiography it become possible to find them in a living person. Later on, new modalities such as computed tomography (CT) and magnetic resonance imaging (MRI) enhanced futher our abilities. It is very important to discover coronary anomalies in a living person, because some of them could lead to sudden cardiac death (SCD). In fact, coronary artery anomalies are the second main cause of the SCD in young athletes. Another importance is driven by the fact, that some of them could lead to lifethreatening complications during cardiac surgery when unknown before the operation.Methods.We prospectively reviewed all coronary angiography films from 2011 to 2016 in our center. Coronary anomalies were reviewed and classified by two independent experienced operators. Patients with congenital heart disease and coronary fistulas were excluded.Results.Out of 5055 patients 148 (2.9%) had coronary artery anomalies of origin and distribution. Those were 120 men (81.1%) and 28 women (18.9%) with an age range between 29 to 88 years. The three most common anomalies were myocardial bridge (48.7%), separate origin of the conus branch (13.5%) and separate origin of the LAD and LCX (8.1%).Conclusion.In our study we found more or less the same types and incidence rates of coronary artery anomalies as in the world literature. We had apparently higher rates of myocardial bridges, compared to average number on angiography studies, but very close to authopsy study rates.
