Case report: a rare case of left-sided sinus of Valsalva aneurysm with concomitant coronary artery fistula and carotid artery aneurysm

SVAs originating from the left coronary sinus are exceedingly rare, but their potential for fatal complications demands early intervention. This case demonstrates that surgical repair of the left SVA, associated coronary fistula, and carotid aneurysm is both safe and effective, and it reinforces the role of genetic testing in patients with atypical presentations of aneurysmal disease. Multimodal imaging and a multidisciplinary approach are essential in guiding treatment decisions in such unusual presentations.
