What are the risks involved with minimally invasive heart surgery?

Similar to standard: For most minimally invasive heart surgery the main difference is the means to access the surgical site. Though less trauma may be needed, the actual surgical procedure itself will be similar and therefore have comparative risk to an "open" case.

Depends: What diagnosis what operation what personal risk factors? Death bleeding recurrence over time stroke infection are the serious but infrequent things we talk to patients about as they consent to operations.
