Minimally Invasive Heart Bypass Surgery

Daniel O'Hair, MD, Cardiovascular and Thoracic Surgeon
Medical Director, Robotic Surgery Center of Wisconsin

Heart bypass surgery uses blood vessels to bypass heart arteries that have become clogged over time with fats, cholesterol and other substances, collectively known as "plaque." The goal of heart bypass surgery is to restore healthy blood flow to the heart and avoid a major blockage.

Through the use of state-of-the-art minimally invasive artery bypass surgery, available at Aurora Health Care, complex procedures to bypass diseased arteries are now performed with less risk and quicker recoveries.

Robotic-Assisted Heart Bypass Surgery

With the da Vinci® Surgical System, surgery is performed without opening the chest.

By way of several
tiny incisions, surgical instruments and 3D visual equipment access the surgical site with minimal disruption to surrounding tissue. Surgeons are able to clearly view important anatomical structures, and with total control of the robotic arms, they perform the most
complex and delicate procedures with enhanced dexterity and unmatched precision.

Experience Counts

Since initiating our robotic-assisted surgery program in 2002, Aurora Health Care physicians have collectively performed more than 4,700 robotic-assisted procedures using the daVinci Surgical System.

Aurora St. Luke's was the first hospital in Southeastern Wisconsin to apply the precision of robotic-assisted technology in heart bypass surgery.

The robotic-assisted heart surgery team is led by Daniel O’Hair, MD, a board-certified cardiovascular and thoracic surgeon with years of experience in robotic-assisted heart surgery procedures.

Robotic-Assisted vs. Traditional Heart Bypass Surgery

  Open Procedure Robotic-assisted procedure
Number of incisions: 1 4 or 5
Size of incisions: 8–10” ½”


Additional benefits of robotic-assisted heart bypass surgery:

  • Significantly less pain
  • Less trauma to surrounding tissue
  • Less blood loss
  • Shorter hospital stays
  • Faster recoveries
  • More rapid return to everyday activities
  • Less scarring
  • Less risk of infection

If you are considering a robotic-assisted surgery, consider asking your physician the following questions:

  • What experience do you have with robotic-assisted surgery?
  • What types of robotic-assisted surgery procedures have you done?
  • How many robotic-assisted surgery procedures have you done?
  • What type of outcomes have your patients experienced?
