title: Left ventricular outflow tract obstruction after mitral valve repair treated with alcohol septal ablation.
abstract: Left ventricular outflow tract (LVOT) obstruction due to systolic anterior motion of the mitral valve (SAM) occurs in 4-5% of patients after mitral valve repair. If conservative treatment is unsuccessful, reoperation is indicated. Treatment options include repeated mitral valve repair or valve replacement and septal myectomy if hypertrophy is present. We report a case of a patient with pre-operatively undiagnosed hypertrophic cardiomyopathy who suffered from progressive dyspnea post-operation due to severe LVOT obstruction with SAM. This case was successfully treated with catheter-based alcohol septal ablation.
