Valve migration into the left ventricular outflow tract (LVOT) during transcatheter aortic valve implantation (TAVI) is a life-threatening complication. An 89-year-old female patient was admitted for TAVI due to severe symptomatic aortic stenosis. After deployment of a balloon-expandable prosthesis, the prosthesis had migrated into the LVOT. The prosthesis was reimpacted to the aortic annulus by a balloon-assisted recapture procedure. Immediately after recapturing the prosthesis with an oversized balloon, the patient’s vital signs deteriorated due to acute aortic regurgitation (AR), and a prompt valve-in-valve (V-in-V) procedure allowed us to stabilize the patient’s condition. This is the first reported case of a V-in-V procedure using an oversized balloon and a larger prosthesis to treat migration of the initial prosthesis into the LVOT. Balloon recapture and V-in-V procedure using an oversized balloon and larger prosthesis for a migrated balloon-expandable prosthesis into the LVOT is feasible, but hemodynamic support should be prepared before recapture and V-in-V because overdilatation of the first prosthesis might cause hemodynamic collapse due to severe AR.
