The Short-term and Mid-term Outcomes of Elderly Patients With Valvular Heart Disease Undergoing Valve Replacement With Biological or Mechanical Prostheses / 中国循环杂志

ABSTRACT

Objectives: To compare the short-term and mid-term outcomes of elderly patients (>60 years old) with valvular heart disease (VHD) underwent bioprosthetic or mechanical valve replacement. Methods: Between January 2007 and December 2010, 559 elderly patients underwent valve replacement in Fuwai Hospital, clinical data of these patients were analyzed retrospectively (319 cases with bioprostheses vs 240 cases with mechanical prostheses). After matching, data from 192 cases in each group were compared. Results: The mortality within 30 postoperative days were similar (2.1% in both groups). All-cause death during follow up was also similar between the two groups (13.6% vs 13.7%, P=0.98). There was no statistically significant difference on the hospital readmission rate between the two groups (25.5% vs 35.9%, P=0.17). No significant difference was found on thromboembolic and hemorrhagic events free survival between the two groups (144 cases vs 138 cases, P=0.78). Conclusions: Short-term and mid-term survival and readmission rate are similar for the elderly VHD patients receiving bioprosthetic or mechanical valve replacement.
