Preoperative risk factor analysis for operative mortality of patients who underwent mitral valve repair in Philippine Heart Center from 2008-2010.

Background: Mitral valve repair is underutilized despite being recommended as procedure of choice for mitral regurgitation. Cardiac surgeons may be less enthusiastic to embark on the procedure due to lack of information that help them in decision-making preoperatively.


Methods: We retrospectively collected and analyzed the charts of all patients (n=102, mean age: 46 years, 58 males) who underwent mitral valve repair alone or in combination with other cardiac operation from January 2008 to December 2010. Multiple logistic regressions was used to determine the independent effect of each factor with operative mortality.


Results: The overall operative mortality is 9%. The risk factors associated with operative mortality are low BMI (OR 0.66 p = 0.022) low BSA (OR 3.51 p = 0.025), NYHA functional class (OR 3.54 p = 0.022 and low LV EF (OR 0.94 p = 0.030).


Conclusion: Mitral valve repair has excellent operative outcome. However, there are risk factors that influence the operative outcome that surgeons should be aware of for preoperative decision making.
