[Dual left anterior descending coronary artery: a case report].
Dual left anterior descending (LAD) artery originating from the right and left coronary arteries is a rare coronary anomaly. A 61-year-old male patient presented with anginal chest pain. He underwent coronary angiography upon detection of hypokinesia in the anterolateral wall of the left ventricle in transthoracic echocardiography. Left coronary angiography showed narrowing of the left anterior descending (LAD) artery after giving the first diagonal and first septal branches, without reaching the apex. There was a 95% stenosis in the proximal first diagonal artery and a 50% stenosis in the midsegment of the first septal artery. In right coronary angiography, another LAD was noted originating from the proximal right coronary artery and having an anterior course similar to the original LAD. It was longer than that originating from the left main coronary artery, giving many septal and diagonal branches. Stent implantation following elective predilatation was performed for stenosis in the proximal first diagonal artery. The patient was symptomless in the third month of treatment.
