64 years old male presented with typical angina for last 4 hours with stable vitals and unremarkable systemic examination. His ECG was suggestive of ST segment elevations in inferior leads with elevated troponin levels. Patient underwent urgent coronary angiography to plan for revascularization. Angiography revealed an interesting and rare coronary anomaly with dual left anterior descending arteries; where one artery came from left coronary and other originated from proximal right coronary. Right coronary artery was culprit in this case which was stented. This patient had type 4 variant of Dual LAD. It is important to be aware of this anomaly particularly while planning for CABG.
