Abstract Background Sinus of Valsalva aneurysm (SVA) is a rare but clinically significant cardiac anomaly, arising congenitally or through acquired causes. Typically, asymptomatic until rupture, this condition can precipitate acute or subacute heart failure via a pathological left-to-right shunt. While surgical repair has long been considered the definitive treatment, advances in high-resolution imaging and percutaneous device technology have established transcatheter closure as a compelling, minimally invasive alternative in anatomically suitable patients. Case Summary We present a case of a ruptured non-coronary sinus of Valsalva aneurysm creating a left-to-right shunt into the right ventricle. Despite the potentially life-threatening hemodynamic implications, the patient maintained stability. Multimodal imaging—including transesophageal echocardiography and computed tomography angiography—precisely delineated the defect and informed procedural strategy. The patient underwent a successful percutaneous transcatheter closure using a patent ductus arteriosus occluder device, with no procedural complications. Follow-up evaluation confirmed complete defect occlusion and preservation of aortic valve integrity, with no residual shunting. Conclusion This case underscores the expanding role of transcatheter interventions in the management of ruptured SVAs, highlighting the importance of meticulous imaging and patient selection to achieve excellent clinical and structural outcomes. It contributes to the growing evidence supporting minimally invasive alternatives to surgery in select structural heart diseases.
