Objective To discuss the influence of early postoperative hemodynamic, postoperative mortality and the incidence of adverse cardiovascular events with the phenomenon of prosthesis-patient mismatch. Methods We retrospectively analyzed the clinical data of 89 patients who had simple aortic valve replacement in our hospital bewteen January 2012 and January 2014. The 89 patients were divided into two groups including a match group (16 females and 48 males with average age of 58.1±10.4 years) and a mismatch group (15 females and 10 males with average age of 65.3±12.8 years). We compared early results between the two groups. Results There is a statistic difference (P < 0.05) in aortic flow velocity, mean pressure gradient, and the maximum pressure gradient between the two groups. The survival rate of the match group is significantly lower than that of the mismatch group (P < 0.05). And there is a statistical difference in adverse cardiovascular event-free incidence between the two groups (P < 0.001). Conclusion The phenomenon of prosthesis-patient mismatch can affect postoperative hemodynamic and lead to heart failure after surgery. And early mortality and the incidence of cardiovascular adverse events in patients are increased due to prosthesis-patient mismatch.
