Can you tell me about minimally invasive heart bypass surgery?

Minimally invasive: Your question is too broad to explain here. Please refer to the patient guide on minimally invasive bypass surgery: http://www.Cts.Usc.Edu/hpg-minimallyinvasivebypasssurgery.Html.

Be more specific: It's a huge topic. There are different definitions of 'minimally invasive' all over the literature. And the options differ for different diseases.
