Hello, My husband had septal myectomy on October 4 2018, he was extremely compromised before surgery.but he did exercise daily and was not overweight. He was discharged 4 days post op and we flew home to San Diego 2 days later, apart from discomfort from the surgery he did amazingly well and was able to walk 4 miles per day with ease after 6 weeks and no symptoms, he takes 50 mgms of Atenolol daily I'm sure if you had other preexisting conditions the recovery is longer. he is 76 now.
