A 38-year-old Marfan patient underwent Bentall\u2009+\u2009Sun's procedure for Stanford type A aortic dissection with severe aortic regurgitation. On the third month after surgery, the patient was readmitted due to exertional dyspnea. Echocardiography revealed a paravalvular leak with significant left-to-right shunting, leading to symptoms including exertional dyspnea, hepatomegaly, and heart failure. After adequate preparation, the leak was successfully closed using a symmetric VSD occluder. Post-procedural imaging showed near-complete resolution of the leak, significant reduction in the pseudoaneurysm size, and improvement in heart failure symptoms. The patient was discharged in stable condition.<\/jats:p>","DOI":"10.3389\/fcvm.2025.1734565","type":"journal-article","created":{"date-parts":[[2026,1,15]],"date-time":"2026-01-15T06:28:09Z","timestamp":1768458489000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Transcatheter
