Predictors of Procedural Success and Durable Outcomes in Percutaneous Mitral Balloon Valvuloplasty: Not Just the Wilkins Score

Global migration means rheumatic heart disease (RHD) and mitral stenosis (MS) remain important issues in Western health systems. Percutaneous balloon valvuloplasty (PMBV) is a durable treatment strategy relying on suitable leaflet characteristics adjudged by Wilkins score. Commissural calcification alone has been thought as reliable Timing PMBV also important. Falling left atrial ejection fraction (LAEF) theorised to predict future MS intervention. This study compared score commissural predictors of procedural success durability; and, observed if LAEF improved post-valvuloplasty. A retrospective case-note audit was conducted patients undergoing at Monash Medical Centre, Victoria, between 1 June 2005 2020. Patients with echocardiograms performed before after were included. Echocardiograms examined cardiologists sub-specialty training. 89 included (86.5% female, 84.3% born overseas). 25.6% had calcification. 44 follow-up data (mean 4.4±3.8yrs), whom 50.0% event-free survival. <8 associated better survival ≥8 (67.7% vs 7.7%, p<0.001), did absence rather than presence (70.4% p<0.001). predicted lower mortality (0.0% 30.8%, p=0.003). Absent (93.4% 76.2%, p=0.029) durability (5.3±4.0yrs 2.4±2.6yrs, p=0.028). patents those (6.3±10.9% -0.3±7.9%, p=0.034). appears Score predicting can durability. Clinical significance improving post-PMBV unclear.
