Rare case of quadricuspid aortic valve: A case report

Quadricuspid aortic valve (QAV) is a rare congenital cardiac anomaly that typically presents in any age with progressive aortic regurgitation. A 55-year-old Bangladeshi woman came with a 3 weeks history of progressive dyspnea, intermittent chest tightness, and palpitations. Trans-esophageal echocardiography confirmed a QAV with central leaflet malcoaptation and mild aortic root dilatation. Further assessment with cardiac computed tomography and magnetic resonance imaging enabled detailed anatomical characterization, severity assessment, and operative planning. Multimodality imaging is crucial for accurate diagnosis, risk stratification and surgical decision-making. This case highlights the value of comprehensive imaging and individualized surgical planning in achieving favorable outcomes in patients with QAV.
