Abstract
A case of a 70 year old female with hypertrophic obstructive cardiomyopathy who underwent alcohol ablation of the interventricular septum, is presented. Following the procedure, the pressure gradient decreased from 120 mmHg to 80 mmHg. However, 30 minutes after ablation the patients developed hypotension and pulmonary oedema. Echocardiography revealed a significant systolic anterior movement of the anterior leaflet of the mitral valve and elevated pressure gradient up to 200 mmHg. The patient underwent urgent surgery (myectomy), followed by the mitral valve replacement with a favourable outcome.
