Complicated Sinus of Valsalva Aneurysm Initially Diagnosed as Atrial Myxoma

Atrial myxoma and sinus of Valsalva aneurysm (SVA) are rare conditions and possibly underdiagnosed in clinical practice. We report an unusual presentation of a left SVA after an episode of infective endocarditis (IE). The SVA extrinsically compressed the left main coronary artery (LMCA), which was initially diagnosed as a left atrial myxoma.
