Type 4 dual left anterior descending coronary artery
نویسندگان
چکیده
Duplication of the left anterior descending (LAD) coronary artery is a rare anomaly (incidence 1%) characterized by a short LAD that terminates high in the anterior interventricular groove and a long LAD that has a proximal course outside the anterior interventricular groove and returns to the groove in its distal course. The Type 4 variant of this anomaly is extremely rare whereby a long LAD arises from the right coronary sinus with a short LAD arising from the left mainstem. We present a case of Type 4 dual LAD which was characterised with multi-detector computed tomography (CT).

Association Between Left Anterior Descending Artery Length with Coronary Artery Dominance: An Angiographic Study
Introduction: Although left anterior descending (LAD) artery supplies a large portion of the myocardium, the amount of blood supply provided by LAD is depended on the length of the LAD. The aim of the current study was to evaluate the association between coronary artery dominance and LAD anatomic types in patients with normal epicardial coronary arteries. Methods:...

Dual left anterior descending coronary artery is a rare congenital anomaly with 4 subtypes. Double left anterior descending coronary artery originating from the left main stem and the right coronary artery (type IV dual left anterior descending artery) has been reported to occur in 0.01% to 0.7% of patients undergoing cardiac catheterization. We report a case of a 49-year-old woman who was foun...
متن کاملA coronary artery anomaly: type IV dual left anterior descending artery
Coronary artery anomalies are seen in about 1.3% of patients undergoing coronary angiography. However, the dual type of left anterior descending (LAD) artery is a rare form of coronary artery anomaly. There are four types of dual LAD; type IV describes the anomaly of a rudimentary LAD artery terminating in the mid-portion of the anterior interventricular sulcus, and the presence of another LAD ...

Coronary artery anomalies are congenital changes in their origin, course, and/or structure. They are the second most frequent cause of sudden death in young athletes. Dual LAD artery is a rare coronary anomaly. We present the case of a 44-year-old man with recent onset exertional angina and documented ischemia whose coronary angiogram and computed tomography (CT) showed type 4 dual LAD artery, ...

Introduction: Although coronary endarterectomy is not an ideal procedure, it is the only available option for cardiac surgeons in some patients with diffuse coronary artery disease. Based on the majority of conducted studies, the results of coronary endarterectomy (including survival, graft patency, and recurrence of the symptoms of myocardial ischemia) are less prevalent than standard coronary...
