Coronary artery anomalies are a diverse group of congenital disorders, with a reported incidence of 0.6 – 1.3%. Congenital absence of the LCX is an extremely rare anomaly, with a frequency of only 0.003% in all patients who undergo coronary angiography. Here, we present a case of 76-year-old female who had an episode of chest pain while she was hospitalized for management of small bowel obstruction with elevated troponin and coronary angiogram showed super-dominant right coronary artery without any obstructive disease.

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.

Myxoma is a common benign tumour found in the heart. On reviewing literature, we found some left atrial myxomas receive blood supply from the right coronary artery. Performing a coronary angiogram in a cardiac tumour has the following uses: (1) it shows the vascularity that can be ligated by the surgeon at operation; (2) if there is a blood supply visible, it may not be an intracardiac thrombus; (3) the coronary angiogram may detect a myxoma even before an echocardiogram does so; (4) some myxomas may bleed into the right atrium or left atrium and this may be seen on coronary angiography. We show here the neovascularity of a left atrial myxoma and its blood supply from the right coronary artery. We recommend that all routine coronary angiograms be reviewed carefully for any signs of tumour vascularity or tumour blush as this would prevent missing early myxomas. Echocardiography is the gold standard for detection of myxomas but literature has a number of intracardiac tumours that were detected only by the tumour blush. Some left atrial tumours have been treated by occluding their blood supply.The absence of a blood supply on coronary angiography could rule out a benign cardiac tumour that usually has a blood supply.

This study aims to assess the normal coronary diameters of patient who underwent coronary angiogram in Patan Hospital. Angiographic and demographic data of a total of 307 patients (155 males, 152 females; mean age 62.09±11.06 years) who underwent elective coronary angiography in Patan Hospital due to suspicion of coronary artery disease between 2017 and 2020 and in whom coronary angiography documented normal coronary arteries without any intra-luminal irregularity were analyzed retrospectively. Proximal diameters of the main epicardial coronary arteries were measured quantitatively using automated software analysis (Allura, Philips). The mean diameter of unadjusted/adjusted left main coronary artery, proximal left anterior descending artery, proximal left circumflex artery, proximal right coronary artery were 4.87±0.85mm/2.8±0.54, 3.8±0.7/2.19±0.439, 3.4±0.7/1.98±0.44, 3.6±0.85/2.07±0.53 respectively. Our study findings contradict the traditional belief that females have narrower coronary arteries than males. Our study showed the females have statistically significant larger unadjusted Right Coronary Artery diameter and adjusted Left Main Coronary Artery diameter. We believe that our findings may contribute to the global data pool of normal coronary diameters and can be utilized in future studies as a database.

Abstract 55-year-old male with history of transient ischaemic attack, excised gastro-intestinal stromal tumour, and osteoarthritis presented to rapid access chest pain clinic with history of atypical chest pain. There were no resting electrocardiographic changes. In accordance with NICE stable chest pain guidelines, a CT coronary angiogram was requested to further assess for any underlying coronary artery disease. This showed normal origin of left main stem (LMS) from left coronary sinus of aorta, however there was an anomalous origin of the right coronary artery (RCA) as a branch from the mid portion of left anterior descending artery (LAD). This was deemed to be an incidental finding with a benign course and not the cause of his symptoms. Coronary anomalies have a reported incidence of 1.3% at invasive coronary angiography (1), and a reported incidence of 0.014-0.066% of single coronary artery (2). Anomalous RCA usually courses from the LMS and courses between the aorta and pulmonary artery. We present an extremely rare variant of single coronary artery arising from the mid LAD without any associated congenital or structural abnormality, on CT coronary angiography (the gold standard for demonstrating coronary anatomy). This is rarely reported in the literature and is a benign coronary anomaly. Abstract P1487 Figure.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction NICE (National Institute of Clinical Excellence) guidelines currently recommend the use of CT coronary Angiogram (CTCA) as the initial test to investigate coronary artery disease in patients with new onset of chest pain. Our aim was to evaluate the relationship between the CT coronary angiogram findings on index presentation, and hospital admissions and re-referral to outpatient clinics in following 2 years. Method Data was accrued via a retrospective analysis of electronic medical records at Sunderland Royal Hospital pertaining to patients who presented to the Rapid Access Chest Pain Clinic (RACPC) and underwent CTCA in 2017.Data included: Presentation – Typical & atypical angina Risk factors profile Investigations including ECG, ECHO, CTCA, perfusion scan and invasive coronary angiography Severity of coronary artery lesion on CTCA Hospital admissions or re-referral to outpatient clinics in 2 year follow up Results In the 235 patients studied, mean age was 56 years with 130 (55.5%) men and 195 (82.9%) presented with atypical angina as shown in table. Out of 195 patients with atypical chest pain only 17 (8.7%) were diabetics and most of them 178 (91%) had Coronary Calcium score of 1-400. Most patients (184) underwent CT coronary angiogram with 39 (21%) having normal coronary arteries, 126 (68%) with mild to moderate coronary artery disease and 19 (11%) with severe coronary artery disease. Subsequent assessments with invasive coronary angiography, myocardial perfusion scan and Treadmill exercise did not reveal significant disease warranting coronary revascularization. Patients with normal or mild -moderate CAD on CTCA 24 (15%) represented with acute chest pain (only one needed PCI) and 6 (3.5%) were referred to outpatient clinics over 2 years follow up. In patients with severe CAD on CTCA, 6 (32%) presented with acute chest pain and 4 (21%) needed PCI. Almost all patients were treated with statins and antiplatelets following CTCA results. Conclusion CT coronary angiography is sensitive and specific in assessment of hemodynamically significant coronary artery disease in non-diabetic patients presenting with angina in outpatient setting. CTCA in patients with normal or mild to moderate CAD also gives confidence to the clinician and prevents further un-necessary investigation and hospital admissions/outpatient referrals.

Highlight:A young adult has activity-triggered atypical chest pain and diagnosed malignant RCA.Congenital anomalies  needed to be aware by cardiologists to help clinical practice.Planning a treatment about management of the CAAs condition should be undertaken by the inter-specialist team. Abstract:We presented a case a young adult with activity-triggered atypical chest pain and diagnosed with anomalous origin of right coronary artery (RCA) from the left coronary sinus with an interarterial course between the aorta and the main pulmonary artery that was detected by CT coronary angiography. This anomaly has been called malignant RCA. Coronary artery anomaly is a congenital condition. Most of the cases remain asymptomatic. This condition is also one of the most causes of sudden cardiac death, because the coronary artery examination is not regularly done. Nevertheless, during high intensity activity, it could be symptomatic and might be lethal. Diagnosing coronary artery anomalies might be tricky and cardiologists must be aware of this. The CAAs condition is a rare situation. The CAAs condition is associated with sudden death, especially intense physical activity. There was no rigid guideline for the management of the CAAs condition, so that planning a treatment in the inter-specialist team should be done.

We here describe 50-year old man presented with sudden onset of left side chest pain associated with diaphoresis and dyspnoea of two days duration. With the impression of inferior wall myocardial infarction (IWMI) electrocardiogram was consistent and Conventional angiograph showed to have high take off right coronary artery from ascending aorta and proximal to mid-99% stenosis. The focus on this report was the challenge to hook and stent high take off right coronary artery origin. So doing interventions in the catheterization laboratory we should be able to do different techniques like hanging type of coronary angiography with different balloons and catheters to overcome this challenge. Patient life was saved and nally discharged with stable condition

Coronary artery anomalies are congenital changes in their origin, course, and/or structure. Most of them are discovered as incidental findings during coronary angiographic studies or at autopsies. We present herein the case of a 70-year-old man with symptomatic severe aortic valvar stenosis whose preoperative coronary angiogram revealed a so far unreported coronary anomaly circulation pattern.

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.
