Multicenter Study
Star GK Bileaflet Mechanical Valve Prosthesis-Patient Mismatch after Mitral Valve Replacement: A Chinese Multicenter Clinical Study.
The aim of this study was to investigate the incidence and immediate and mid-term effects of heart valve prosthesis-patient mismatch (PPM) after mitral valve replacement using the GK bileaflet mechanical valve. ⋯ PPM after mitral valve replacement influences postoperative hemodynamics. Thus, larger-sized GK bileaflet mechanical valves are often used to reduce the risk of PPM.
