Prosthesis-patient mismatch after surgical aortic valve replacement with aortic annular enlargement in small aortic annuli.
OBJECTIVES Aortic annular enlargement (AAE) during surgical aortic valve replacement (SAVR) is performed to facilitate implantation of larger prostheses in patients with small aortic annuli and mitigate prosthesis-patient mismatch (PPM). However, the clinical impact of residual PPM after AAE remains uncertain. METHOD...
