Time	Events
6 years earlier	Surgical aortic valve replacement (SAVR)
5 years earlier	Re-do SAVR with a 23 mm Trifecta bioprosthesis due to endocarditis
6 months earlier	Patient with dyspnoea being diagnosed as structural valve deterioration (peak velocity of 4.1 m/s, mean gradient of 40 mmHg, and no paravalvular leak)
Day 0	Valve-in-valve transcatheter aortic valve replacement (Evolut PRO + 26-mm)
Day 1	Transthoracic echocardiography with high residual aortic gradient (peak aortic velocity of 4.0 m/s, mean aortic gradient of 37 mmHg) and computed tomography showing underexpansion of transcatheter heart valve
Day 3	Development of acute decompensated heart failure
Day 5	Balloon aortic valvuloplasty (Atlas Gold PTA Balloon Dilatation Catheter 20-mm), leading to balloon entrapment to the strut of Evolut PRO+. Subsequent successful removal of entrapped balloon with transseptal snaring technique.
Day 7	Transthoracic echocardiography showing decrease of aortic gradient (peak aortic velocity of 2.0 m/s, mean aortic gradient of 8 mmHg)
Day 13	Discharge to home without any symptoms
