“…CAAs are classified as "giant" either when their diameter is four times more than the reference vessel diameter, or when they have a diameter larger than 8 mm [ 5 ]. It is an asymptomatic progressive condition that is incidentally discovered through coronary angiography; it can have a poor outcome, even in the absence of associated coronary artery disease.…”

Coronary artery aneurysm (CAA) is characterized by a localized dilation of one or more of the coronary arteries with multiple etiologies, including congenital, acquired, or connected to auto-inflammatory diseases with multiple shapes and classifications. It is usually diagnosed incidentally during coronary imaging and can have variable clinical outcomes, ranging from asymptomatic to sudden cardiac death with a generally poor prognosis. Management of this condition faces a clinical dilemma due to the lack of clear guidelines or randomized trials. Treatment should be individualized based on symptoms, shape, and comorbidities. Herein, we present the case report of a 27-year-old female patient with no prior medical conditions. However, she presented with palpitations, and a compressive mass located over the right atrium was identified in the patient. After undergoing cardiac catheterization and coronary scanning, a giant aneurysm of the sinoatrial branch was detected with an aneurysmal left main that was retrieved surgically with good recovery and postoperative course.

“…Hiraoka et al 6 2012 reported an atherosclerotic giant SNA aneurysm with a fistulous opening into the left atrium. Huang et al 7 2018 presented a case of a giant SNA aneurysm with a fistulous tract opening into the right atrium, which on histological examination of the biopsy specimen was revealed as fibrous hyperplasia. Our case of a congenital giant aneurysm of the SNA with a fistula into the right atrium is unique and is the first reported case of this nature.…”

Coronary artery aneurysms (CAAs) occur when an artery dilates 1.5 times the reference vessel. 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. Coronary angiography illustrated that the SNA branched off the left main coronary artery, and the aneurysm communicated with the right coronary artery. The aneurysm was partially resected and plicated.

Coronary aneurysm located just above the left main coronary artery (LMT) is rare and difficult to treat. How the aneurysm is accessed is very important as it determines the result of the surgery. A 70-year-old man with a large coronary aneurysm (40 mm in diameter) in the LMT underwent surgery to prevent its rupture; however, there was severe adhesion. Initially, dissection of the ascending aorta or the pulmonary artery seemed necessary to access the aneurysm; however, the process was possible with limited dissection between the ascending aorta and the pulmonary artery, and we succeeded in firmly closing the LMT site of entry.
