Transcatheter aortic valve replacement as an alternative to open surgical repair is rapidly becoming more used in high-risk patients with aortic stenosis. Transcatheter aortic valve replacement offers the benefit of being much less invasive than traditional surgical repair and has evolved as a therapeutic option for patients with prohibitive surgical risk or those deemed surgically inoperable. Nevertheless, despite its potential to mitigate risk in this frail population, it comes with its own unique set of complications. Technological advancements in valve structure, function, and delivery have and continue to attempt to minimize these risks. This review aims to summarize current advancements in transcatheter aortic valve replacement technology while also introducing areas of future direction in this exciting new field.
