CTR was defined using validated International Classification of Diseases, 9th Edition, Clinical Modification diagnosis (ICD9-CM) codes. </span></p><p class="p1"><span class="s1"><strong>Results:</strong> A total of 37,287 (14,833 mitral valve repair, 7780 mitral valve replacement) CTR cases were identified. Overall, in-hospital mortality in CTR decreased by 3% from 2000 to 2012 (<em>P</em> &lt; 0.001). From 2000 to 2012, the rate of mitral valve repair increased from 27.2% to 46.4%, (<em>P</em> &lt; 0.001) with a concurrent decrease in the rate of mitral valve replacement (from 27.8 to 17.7%, <em>P</em> &lt; 0.001). After multivariate adjustment, patient age (OR = 1.04, 95% CI 1.03-1.06, <em>P</em> &lt; 0.001), congestive heart failure (CHF) (OR = 2.08, 95% CI 1.19-3.64, <em>P</em> = 0.01), myocardial infarction (MI) (OR = 3.58, 95% CI 2.10-6.11, <em>P</em> &lt; 0.001), Deyo/Charlson comorbidity index (OR = 1.23, 95% CI 1.07-1.41, <em>P</em> &lt; 0.003) and use of the intra aortic balloon pump (IABP) (OR = 4.81 95% CI 2.71-8.55, <em>P</em> &lt; 0.001) were found to be independently associated with greater odds of mortality in these patients. Additionally, mitral valve replacement was significantly associated with higher costs of hospitalization (coefficient 15693, 95% CI 12638-18749, <em>P</em> &lt; 0.001)</span></p><p class="p1"><span class="s1"><strong>Conclusion:</strong> Mitral valve repair is associated with reduced inpatient mortality and costs compared with mitral valve replacement. A substantial increase in the percentage of cases undergoing mitral valve repair with a concurrent decrease in cases undergoing mitral valve replacement were observed. Increasing age and comorbidity index, history of CHF and MI, and use of IABP were identified as factors that could increase the risk of mortality in patients with CTR.</span></p> ER -
