Fig. 1From: Mitral valve replacement complicated by iatrogenic left ventricular outflow obstruction and paravalvular leak: case report and review of literatureIntra-procedural Trans-esophageal Echocardiography. a Pre-procedure continuous wave Doppler velocity tracing showing elevated gradient across LVOT which is characteristic of dynamic outflow obstruction. b After alcohol septal ablation, continuous wave Doppler velocity still showed elevation of gradient across LVOT. c Continuous wave Doppler velocity showing reduction in gradient across LVOT after injection of glueBack to article page
