Performance of Contemporary Risk Scores for Mitral Valve Surgery

Abstract

the same or better in 69 (95%) of AR and 64 (88%) of MR. 3/9 cases with dilated LV at T1 had returned to normal at T2. There was no late systolic dysfunction or mitral stenosis among non-operative cases. 78% of cases had a known BMI > 30kg/m at final assessment. The obese subjects were more likely to have LVH, diastolic dysfunction or aortic root dilatation. Conclusion: For childrenwho escape early surgery and are compliant with BZP valve regurgitation improves in 85%. Late deterioration to severe AR or MR is rare without ARF recurrence. A concerning finding is the emergence of an obese ‘footprint’ on the young heart.
