Minimally Invasive Cardiac Surgery
Minimally Invasive Cardiac Surgery (MICS) - This is a procedure performed through several small incisions instead of the traditional open-heart surgery. This is favored by surgeons and patients because of reduced post-operative discomfort, faster healing times and lowered risk of infections or complications.
The incision used for minimally invasive heart surgery is about 3 to 4 inches instead of the 6- to 8-inch incision required for traditional surgery.
Primarily, there are two types of MICSs.
- Minimally Invasive Valve Surgery
- Minimally Invasive CABG Surgery
Minimally Invasive Valve Surgery
Valve surgeries, including valve repairs and valve replacements, are the most common type of minimally invasive surgery, accounting for 87 percent of all minimally invasive cardiac surgeries performed at Cleveland Clinic.
Minimally Invasive CABG Surgery
Minimally invasive direct coronary artery bypass graft (MIDCABG) surgery is an option for some patients who require a left internal mammary artery bypass graft to the left anterior descending artery.
Off-pump/beating heart bypass surgery allows surgeons to perform surgery on the heart while it is still beating. A medication may be given to slow the heart during surgery, but the heart keeps beating during the procedure. This type of surgery may be an option for patients with single-vessel disease (such as disease of the left anterior descending artery or right coronary artery).
Traditionally, CABG surgery is performed using a heart-lung bypass machine. This machine allows the heart's beating to be stopped, so the surgeon can operate on a surface that is blood-free and still. The heart-lung bypass machine maintains life despite the lack of a heartbeat, removing carbon dioxide from the blood and replacing it with oxygen before pumping it around the body.
During off-pump/beating heart surgery, the heart-lung machine is not used. The surgeon uses advanced operating equipment to stabilize (hold) portions of the heart and bypass the blocked artery in a highly controlled operative environment. Meanwhile, the rest of the heart keeps pumping and circulating blood to the body.
