摘要
Background Pulmonary artery aneurysms (PAAs) are rare and they are infrequently diagnosed due to the non-specificity of their symptoms. However, their related complications, mainly described in patients with pulmonary hypertension (PH), are associated with significant morbidity and mortality.Case summary We report the case of a 64-year-old woman previously operated on for pulmonary valve stenosis, who presented with rapid worsening of dyspnoea and sudden onset of chest pain. Physical examination did not show heart failure symptoms, and an echocardiogram showed significant but not severe pulmonary regurgitation with preserved right and left ventricular function. Estimated pulmonary artery (PA) pressure was normal. As myocardial ischaemia was suspected the patient underwent a coronary computed tomography angiography that showed compression of the left main coronary artery by a large PAA. Early diagnosis led to surgery that solved her symptoms.Discussion Comprehensive medical evaluation of symptomatic patients with PA dilatation, even in the absence of PH, is key to rule out the possibility of serious complications as soon as possible.
