Background: Redo aortic interventions after failed transcatheter aortic valve replacement (TAVR) are challenging, particularly with low coronary heights and dense frame ingrowth. Case Description: An 83-year-old woman with prior TAVR developed severe prosthetic stenosis. Surgical Resection of Prosthetic Valve Leaflets Under Direct Vision (SURPLUS) with implantation of a balloon-expandable aortic valve and intraoperative low-dose indocyanine green (ICG) near-infrared (NIR) angiography was performed. Real-time NIR imaging confirmed symmetric coronary opacification. The valve was well seated with improved ejection fraction (60–65%), and recovery was uneventful. Conclusion: SURPLUS with ICG–NIR angiography ensured coronary patency and safe hemodynamic restoration.
