“…It may play a protective role for myocardium if significant coronary artery stenosis or atherothrombosis develops in one of the two connecting vessels (10). On the other hand, myocardial ischemia can be resulted from a coronary steal, resulting in inadequate perfusion, particulaly when unidirectional flow is observed (2). There were only two cases in the literature similar to our case.…”

“…Coronary circulation's anomalies and variants are classified into four main groups; anomalies of origin, distribution, course and termination (1,4). Intercoronary communication or coronary arcade is a very rare coronary artery termination anomaly with unidirectional or bidirectional blood flow between two coronary arteries and is seen during coronary angiography in patients with or without coronary artery stenosis (5,6). The true Figure 1.…”

Koroner arterler arası bağlantı veya koroner ark, iki koroner arter arasında tek yönlü veya iki yönlü akımın olduğu ve açık uçlu dolaşımın bulunduğu nadir görülen bir konjenital koroner arter anomalisidir. 85 yaşında kadın hasta acil serise tipik tarzda göğüs ağrısı ile başvurdu. Elektrokardiyografi ve ekokardiyografisinde transmural miyokard infarktüsü bulguları yoktu. Koroner anjiografide sağ koroner arterin (RCA) tıkalı olduğu ve sol ön inen arter (LAD) arasında bağlantı olduğu saptandı. RCA'da tıkayıcı lezyonun bulunduğu ve LAD ile RCA arasında koronerler arasında bağlantının bulunduğu bu çok nadir görülen koroner anomaliden literatürde sadece iki adet bulunmaktadır. Bu yazıda bu anomalinin aterosklerotik koroner arter hastalığına karşı potansiyel kardiyoprotektif rolü tartışılmıştır.Anahtar Kelimeler: Koroner arter anomalisi, koroner ark, koronerler arası bağlantı, koroner anjiografi Intercoronary communication or coronary arcade is a rare congenital coronary artery anomaly in which there is an open-ended circulation with unidirectional or bidirectional blood flow between two coronary arteries. A 85-year-old woman was admitted to the emergency service with typical chest pain. There was no evidence of transmural myocardial infarction in the results of electrocardography and echocardiography. An intercoronary connection between the left anterior descending artery (LAD) and the right coronary artery (RCA) with an obstructive lesion was detected on coronary angiography. This is a very rare coronary anomaly, only two cases of intercoronary communication between LAD and RCA with an obstructive lesion were found in the literature. The potential cardioprotective role of this entity against atherosclerotic coronary artery disease is discussed in this case report.

“…Histologically, collaterals that develop in the presence of obstructive coronary artery disease are composed of endothelium supported by poorly organized collagen, muscle, and elastic fibers; in contrast, ICCs are similar to an epicardial vessel with a well-defined muscular layer. ( 10 ). Persistence of fetal coronary circulation has been suggested as the underlying mechanism for the development of ICC.…”

Coronary artery aneurysm is a rare disease. It occurs in the epicardial space, mostly along the course of major coronary arteries. Here, we report a case of a giant incidental aneurysm embedded in the basal posterior wall of the left ventricle. A 43-year-old woman was referred to our institution for the evaluation of cardiac palpitations that had been present from the previous 2 months. She reported no medical history (such as Kawasaki's disease or hypertension) or previous operative history. Echocardiogram and subsequent cardiac CT revealed a giant aneurysm in the left ventricle, with a direct fistulous connection to a dilated and tortuous left circumflex artery, which showed direct communication with the straight right coronary artery.

“…9 Intracoronary communications are a very rare subset of coronary artery anomalies with uni-or bidirectional blood flow between two or more coronary arteries. 10 These anomalies are mostly asymptomatic, however, clinical presentation in adults may result from myocardial ischaemia manifesting as angina, syncope, arrhythmias and even sudden death. 11,12 In our study, we found a communicating branch of the anterior interventricular artery was anastomosed with RCA on the anterior aspect of infundibulum.…”

BACKGROUND Knowledge of coronary artery branching pattern and their anomalies that occur during foetal development is essential for clinicians. They are associated with high incidence of morbidity and mortality due to congenital heart diseases. Failure to recognise them can lead to inadequate or prolonged procedures and may also lead to misdiagnosis and complications such as accidental ligation. MATERIALS AND METHODS A properly embalmed and stored 50 human heart specimens were dissected in the age group of 20-65 years to study the course and distribution of coronary arteries. The study was conducted in dissection hall,
