“…The young patient in our case presented with abnormal and dynamic ST segments changes on ECG. Similarly, a case was reported of a 51-year-old male with missing LCx with T wave inversion in leads V3-4-5-6 as well as isoelectric T wave in leads II, III, aVF and I, and aVL [ 17 ]. Also, a case of a 46-year-old male with congenital absence of LCx was described with T wave inversions on the ECG [ 15 ], indicating that congenital absence of LCx is associated with ECG changes.…”

Patient: Male, 20Final Diagnosis: LCx agenesisSymptoms: Chest pain • syncopeMedication: —Clinical Procedure: —Specialty: CardiologyObjective:Congenital defects/diseasesBackground:This case study demonstrated that although highly symptomatic, agenesis of the left circumflex artery was a benign finding. Anomalies of the coronary arteries were found to be the cause of sudden death in a young individual. Left circumflex anomalies were not associated with major cardiac events.Case Report:A 20-year-old male was admitted due to syncope preceded by chest pain. His electrocardiogram (ECG) showed global ST segment elevation as well as biphasic T waves in anterior precordial leads. Troponin T values were normal. Echocardiography was normal. Computerized axial tomography (CAT) scan showed agenesis of the circumflex artery with a super-dominant right coronary artery. Myocardial scintigraphy showed no perfusion defects. Exercise test did not present any arrhythmias. Tilt table test displayed stable blood pressure and pulse response. A reveal recorder registered no malignant arrhythmias. A coronary angiography confirmed the finding of the CAT scan and showed no collateral vessel development.Conclusions:This case demonstrated that agenesis left circumflex artery although presenting with severe symptoms, such as chest pain, is a benign finding. Chest pain was not correlated to perfusion defects in this case. Although the patient experienced loss of consciousness, there was no objective support for cardiac origin as no malignant arrhythmias were found.

“…Congenital absence of left circumflex artery is an incidental benign finding on coronary angiography and most of these patients present with chest pain on exertion. [7][8][9][10][11] Varela et al [7] reported a case of congenitally absent left circumflex with block of right coronary artery causing inferolateral and posterior wall myocardial infarction. The various investigations available to diagnose this rare entity include transthoracic, transoesophageal echocardiography, cardiac magnetic resonance imaging, MDCT coronary angiography and invasive coronary angiography.…”

A 54-year-old male patient came to Radiology Department for MDCT coronary angiogram as routine master health checkup. The patient had no complaints of chest pain. His blood pressure was 126/82 mmHg. The patient had no history of diabetes or any other illness. His blood investigations like complete blood count, renal and liver function tests were normal. As the patient requested for CT coronary angiography as part of health checkup , it was done.

“…The previously published reports described patients who underwent angiography for exertional chest discomfort and were found to have either high-grade stenosis in a dominant RCA [3] or no significant coronary stenosis [4]. We have also found few reports of congenitally absent LCX and super-dominant RCA but with normal LAD origin which might carry similar clinical significance and further emphasize on the importance of precise morphological and functional evaluation of the CAA in selecting the best treatment modality and better prognosis [5-8].…”

The left anterior descending artery originating from the right coronary sinus is very unusual. An absent left circumflex is very rare with a few reported cases in the literature. We report a combination of a non-dominant left anterior descending artery arising from the right coronary cusp and an absent left circumflex artery in a 60-year-old male presenting with ST-segment elevation myocardial infarction. The patient was managed by percutaneous intervention and recovered well. This case demonstrates an extremely rare combination of coronary anomalies.
