My wife had a severe problem and about 8 years ago she had to have surgery. I think she was in Baptist Hospital in Pensacola for it. The doctor said that was the only thing he did. He went into the groin, ran a laser up into her right ventricle and supposidly poked thru to the left ventricle where the problem was. He zapped a small section of the muscle wall and it cured it. He said they were usually a one day stay procedure, but it was later in the day for her and she stayed the night.
