The delayed southern migration of a transcatheter aortic valve

Abstract

Transcatheter aortic valve replacement has emerged as a favourable alternative in patients with severe symptomatic aortic stenosis who are at intermediate and/or high risk for open aortic valve replacement. While transcatheter aortic valve replacement has been shown to be a safe alternative to surgical aortic valve replacement in those populations, the procedure is not without risks. Transcatheter heart valve migration can occur, albeit rarely, in an acute, subacute and delayed fashion. This complication can have fatal consequences if not managed appropriately. We describe a patient who underwent a transcatheter aortic valve replacement and had evidence of transcatheter heart valve subacute migration into the left ventricular outflow tract.
