Fibrosing Mediastinitis Associated With Complete Occlusion of the Left Main Pulmonary Artery

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.

Abstract Continuous heart rhythm monitoring with cardiac event recorders is increasing in clinical practice and may be helpful in diagnosing a wide range of disorders and pathologies. This case study describes the case of an 80-year-old female patient with a medical history of previous cardiac surgery in which a cardiac event recorder had to be retrieved from the left main pulmonary artery.

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.
