Aortic valve replacement and prosthesis-patient mismatch in the era of trans-catheter aortic valve implantation

摘要

ObjectiveThe treatment strategy for aortic stenosis (AS) has been changing due to newly developed valvular prostheses and trans-catheter aortic valve implantation (TAVI). To determine the role of new modalities for AS with a small aortic root, papers using the concept of prosthesis-patient mismatch (PPM) were reviewed.
