Box 1: Levels of ascent in minimally invasive cardiac surgery. Level 1 Direct vision: Limited (10-12 cm) incisions Level 2 Direct vision/video assisted: Mini (4-6 cm) incisions Level 3 Video directed and robot assisted: Micro (1.2-4 cm) incisions Level 4 Robotic (computer telemanipulation): Port (<1.2 cm) incisions Box 2: Current patient selection: videoscopic or video-assisted mitral valve surgery.
As for the future, minimally invasive cardiac surgery is likely to become more widely adopted as growth in this niche market and cardiac surgery as a whole is often patient-driven, much in the same way that percutaneous intervention for multivessel disease has been.
Surgical site infections after minimally invasive cardiac surgery
pose a challenge to the clinician.

"Guidant continues to be an innovator in the rapidly expanding minimally invasive cardiac surgery
market," said Jay Watkins, president of Guidant's Cardiac & Vascular Surgery Group.
The minimally invasive cardiac surgery
The new systems are designed for a wide range of cardiac procedures, including less invasive open-chest surgery, aortic valve replacement, and stopped- and beating- heart minimally invasive cardiac surgery
In the two-step procedure, Douglas Boyd, MD, director of the Minimally Invasive Cardiac Surgery
Program at London Health Sciences Centre, first used Computer Motion's ZEUS Robotic Surgical System to perform an endoscopic, single-vessel heart bypass surgery on a 55 year-old male patient's left anterior descending artery.
