Abstract

Objective: To investigate the imaging characteristics of Valsalva sinus aneurysm on electrocardiography-gated multidetector computed tomography. Subjects and Methods: A cross-sectional descriptive study was conducted on 43 patients diagnosed with Valsalva sinus aneurysm between 2021 and 2025 at Hanoi Heart Hospital. Results: The mean age was 43 years, with a male-to-female ratio of 1.5:1, 21 cases were unruptured and 22 were ruptured. Most patients were symptomatic (95%), most commonly systolic or continuous murmurs along the left sternal border (65%) and dyspnea (56%). Congenital aneurysms accounted for 72,1% of cases, and acquired forms for 27,9%. The aneurysm originated from the right coronary sinus in 70% of cases, from the intersinus region in 12%, and from the left coronary or non-coronary sinus in 9%. Ruptures occurred mainly into the right ventricle (40,9%) and left ventricle (27,3%). Common associated conditions included aortic regurgitation (34.9%), ventricular septal defect (27.9%), and infective endocarditis (25.6%). Echocardiography yielded a correct diagnosis in 81.4% of cases. Conclusion: Sinus of Valsalva aneurysm is a rare cardiac anomaly, either congenital or acquired, that can cause serious complications. Electrocardiogram-gated multidetector computed tomography is a non-invasive, reliable modality that plays an important role in diagnosis and treatment planning.
