Huge Left Atrial Myxoma and Concomitant Silent Coronary Artery Disease in a Young Man.

Severe but silent coronary artery disease may rarely exist in young patients with a low-risk profile but with a family history of coronary artery disease. We describe the case of a 33-year-old Caucasian male with progressive shortness of breath caused by a huge left atrial myxoma who was diagnosed to have significant coronary artery disease in the preoperative assessment. After investigations, the patient underwent resection of the left atrial tumor and coronary artery bypass grafting (CABG) with a successful outcome. Even in the case of a young male, it may be prudent to investigate silent coronary artery disease in the presence of cardiovascular risk factors and family history of coronary artery disease. The learning objective of this case is to debate about the usefulness of a preoperative coronary study even in the young population with cardiac nonischemic pathologies (ie, valve pathology, cardiac tumors, etc.).
