Giant Coronary Aneurysm

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.

A 36-year-old woman was seen with complaints of exertional chest pain and shortness of breath. Her medical history included atrial fibrillation and diabetes. Physical examination was unremarkable except for an irregular cardiac rhythm. Myocardial perfusion imaging revealed the presence of a large area of infarction involving the entire anterior and apical walls and part of the anteroseptal wall with minimal periinfarct ischemia. Computed tomography coronary angiogram revealed an anomalous left main coronary artery arising from the main pulmonary artery. Right and left heart catheterizations demonstrated moderate pulmonary hypertension with a slight step-up in oxygen saturation between the right ventricle and main pulmonary artery. Coronary angiography showed a large tortuous right coronary artery with collaterals to the left anterior descending artery that drained into the main pulmonary artery. She was referred for surgery. This case demonstrates a rare coronary artery anomaly in an adult where survival is dependent on collateral circulation.

Left main coronary artery (LMCA) disease due to external compression by a dilated main pulmonary artery (MPA) is an uncommon clinical entity. Here, we describe a 52-year-old woman with pulmonary arterial hypertension (PAH) and anteroseptal old myocardial infarction (OMI). The cause of the OMI was external compression of the LMCA by the dilated MPA and aneurysm of the left coronary sinus of Valsalva. The patient’s sister (aged 56 years) had also been diagnosed with PAH and both women had a novel heterozygous splicing mutation, IVS2-2A > G (c.374-2A > G in NM_001456), in the filamin A ( FLNA) gene. To our knowledge, this is the first report of HPAH which is likely to be due to FLNA mutation and compression of the LMCA between a dilated MPA and aneurysm of the left coronary sinus of Valsalva.

Patient Reported

A 51-year-old woman with exercise angina and a history of pulmonary artery hypertension related to a previous pulmonary thromboembolism, was referred to our hospital. Computed tomography and coronary angiography showed a 95-mm aneurysm of the main pulmonary artery, which totally occluded the left main coronary artery. After a multidisciplinary evaluation, we recommended heart-lung transplantation, but the patient refused any kind of surgical procedure. Due to the chronic occlusion, stenting of the left main coronary artery was unfeasible. With no other options available, we could only start pulmonary antihypertensive therapy. At the 1-year follow-up, the patient reported relief of her angina.
