A Patient With Bicuspid Aorta and Intercoronary Continuity A Rare Variant of Coronary Circulation

Intercoronary communication is an exceptionally rare congenital malformation. A 43-year-old male was admitted to our cardiology department with symptomatic stable angina. ECG and echocardiography was normal. Exercise electrocardiography showed ST depression in inferior leads. No atherosclerotic plaque in the coronary arteries was detected on coronary angiography. However, a unidirectional intercoronary communication between the circumflex and right coronary arteries, which was leading a coronary steal from right to left, was observed. Although intercoronary communication is generally not related with ischemia, ischemic symptoms and exercise ECG changes of this case suggested that unidirectional flow might cause myocardial ischemia via coronary steal. Consequently, intercoronary communication, a very rare coronary anomaly and a cause of ischemia, is discussed in this case report.

“…In the largest angiographic review by Yamanaka and Hobbs, the incidence of this entity was reported to be 0.002 % among 126595 cases (7). Arat-Ozkan et al examined 12.674 coronary angiograhy records and reported one case with intercoronary communication (8). Abreu et al rewieved ten years angiography record of 9388 patients and identified two cases with intercoronary communication (4).…”

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.
