They occur most commonly because of atherosclerosis. CAAs are a rare phenomenon, and it is even rarer to find a giant CAA, which is roughly defined as a size 400% above the reference vessel. Giant CAAs are commonly found in the right coronary artery. The sinoatrial nodal artery (SNA) is among the least common sites for CAA involvement. Sometimes, communication exists between the aneurysm and a chamber of the heart or a great vessel. The consequences of the fistula depend on its size. Because of the rarity of the condition, guidelines are not well developed. However, small CAAs can be managed conservatively, whereas giant CAAs require resection, ligation, and bypass grafting. CAAs have a predilection for males and the elderly. We describe a 40-year-old South Asian woman presenting with mild dyspnea on exertion of 1 year's duration. Echocardiography showed a 60×60 mm cystic sac, subsequently confirmed by computerized tomography, which showed 3 large aneurysms (70×61 mm) and 3 small aneurysms in the SNA.

Among these anomalies, a unique cardiac abnormality known as a dual left anterior descending artery (LAD) stands out. A dual LAD is characterized by the presence of 2 LADs in the anterior interventricular sulcus. This structural deviation consists of a shorter LAD that terminates high in the anterior interventricular sulcus and a longer LAD that extends to the distal sulcus, supplying blood to the cardiac apex. Percutaneous procedures on dual LADs are even less frequent. We describe a 53-year-old woman with typical burning chest pain, ST-elevation in leads I and aVL, and positive troponin I enzyme. Coronary angiography revealed a thrombotic lesion with 99% stenosis at the proximal part of the LAD. The main LAD originated properly from the left coronary cusp, and the remainder of its course was supplied by a second branch originating from the right coronary cusp. Computed tomography angiography and echocardiography were performed for the LAD course. The patient was discharged after an uneventful 1-week hospital stay. Our case is particularly noteworthy for several reasons. Firstly, this dual LAD anomaly is uncommon, and patients with dual LADs less frequently have a ramus artery.
