<p>Coronary artery fistula (CAF) is a rare entity. Sometimes it may associate with mild diffuse or segmental coronary ectasia. CAF with giant coronary artery is exceptionally rare. We present a unique case of a 49-year-old female patient with a giant right coronary artery of diffuse ectasia coexisting with a fistula draining into the right ventricle. To our best knowledge, CAF with diffuse coronary ectasia of such giant size has never been reported. The patient was treated successfully by resection of the dilated right coronary artery, fistula closure, and coronary artery bypass grafting.</p>

Occlusion of a coronary artery by an acute type A aortic dissection presents a life-threatening emergency that is rarely seen and easy to misdiagnose. We present the case of a 75-year-old male who experienced sudden onset of severe left-sided chest pain due to an acute type A aortic dissection that obstructed the right coronary artery. Following an initial misdiagnosis of acute coronary syndrome, imaging revealed the presence of an aortic dissection. An emergency modified Bentall procedure was performed, in which the damaged aorta and aortic valve were replaced.

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.

Right coronary artery aneurysms are rare and may result from severe coronary disease, with few cases described in the literature. Mortality is high, and therapy is still controversial. We report the case of a 72-year-old woman with arterial hypertension, and a family history of coronary artery disease, who evolved for 2 months with episodes of palpitations and dyspnea on moderate exertion. During the evaluation, a giant aneurysm was found in the proximal third of the right coronary artery. The patient underwent surgical treatment with grafting of the radial artery to the right coronary artery and ligation of the aneurysmal sac, with good clinical course.
