myok - listening to the jpm presentation, surgery was mentioned as the primary alternative to drugs with no mention of ASA. I was under the impression that ASA had penetrated further given its lower morbidity. FWIW below are the American and European registry data. Hard to tell what the higher order effect is when looking at structural issues (leaflets, muscles) vs hypercontractility.
These are all very sick patients nyha III and IV. You would want this done at a center with open myomectomy skills and volume in case backup is needed.
