“…An unusually long left main coronary artery or super-dominant right coronary artery may be a clue for absence of LCX. Sato et al reported an RCA critical lesion with absence of LCX [12]. This condition should be evaluated as equivalent to two-vessel disease including both the RCA and LCX.…”

Absence of left circumflex coronary artery: case report and minireviewBrak gałęzi okalającej lewej tętnicy wieńcowej -opis przypadku i przegląd piśmiennictwa S Su ul le ey ym ma an n E Er rc ca an n 1 1 , , I Ib br ra ah hi im m S Sa ar ri i A b s t r a c tAbsence of the left circumflex coronary artery (LCX) is a very rare coronary anomaly. The anomaly has been reported in only 0.003% of all patients who underwent routine coronary angiography. Although rare, the failure to visualize a coronary artery in its expected anatomical location might cause life-threatening complications such as total occlusion with acute coronary syndromes. In the present paper, we report a patient with absent LCX and discuss the previously reported cases in terms of diagnostic and clinical importance, association with atherosclerosis and other anomalies. We searched Medline (www.ncbi.nlm.nih.gov) for cases of absent LCX and found that so far absence of LCX has been reported 27 times and in 32 cases. Here in this case report and minireview we discuss the characteristics of the present case and previous 32 cases with absence of LCX. The majority of the patients were over 30 years old at the time of diagnosis and the condition is more common in females. Although absence of LCX is generally considered as a benign entity, it might be atherosclerotic and can cause acute coronary syndromes including myocardial infarction and be associated with other anomalies. Proper diagnosis of the absence of LCX is very important because it can be misinterpreted as a totally occluded LCX. In subjects with absent LCX, infarction in the superdominant RCA might be more dangerous. It is more common in females and although conventional coronary angiography is the most widely used diagnostic modality, multidetector computed tomography might also be helpful.

“…Recently a coronary multidetector-row computed tomography (MDCT) can be a useful tool to understand the coronary artery anomalies further in addition to the conventional coronary angiography [6]. Because further detailed information of coronary artery anomalies including the anomalous origin of coronary ostium may not be confirmed only by the conventional coronary angiography although it has been regarded as the gold standard for confirming a variety of coronary artery disease.…”

“…To our knowledge, this is the first report describing MSCT findings of this rare anomaly. MSCT provides information of not only coronary artery luminal narrowing, but also of threedimensional comprehension of the whole coronary artery system, which is useful for the diagnosis of congenital coronary artery anomalies [6]. …”
