Hi i'm getting open heart surgery in 2 months i'm wondering if there is anyway they won't have to break my sternum? will i lose muscle after surgery?

Maybe: It really depends on what type of surgery you need. It also depends on what your surgeon feels comfortable with. But a lot of mitral, aortic valve surgeries can be done this way. Also closing a hole like an ASD and doing limited bypasses at times. I tell my patients my first goal is to do a good job. My second goal is to do it "sexy". But good job comes first.

Yes depends on type: For instance mitral valve repair, atrial septal defect repair can be performed via small incision on the right side of chest and aortic valve replacement can be performed via small incision at the top of the chest.

Heart suregry: You will not lose muscle after surgery. There are ways to avoid breaking sternum. Depending on what kind of surgery, sternal incision may still be the safest choice.
