Prosthesis–Patient Mismatch After Aortic Valve Replacement: Effect on Long-Term Survival

The authors used a single institution data base to assess very long-term outcomes after AVR to determine the effects of prosthesis-patient mismatch.  Among 673 pts, 24% had mismatch.  Mean follow-up was nearly 18 years.  On multivariable analysis, mismatch was not a significant determinant of long-term survival.
