Coronary Artery Bypass Grafting is a surgical treatment for heart disease that is used to improve blood flow to the heart in people with severe coronary artery disease or worsening chronic heart failure. It involves the use of a blood vessel to bypass one or more blocked coronary arteries. CABG can be performed using traditional open heart surgery or via minimally invasive surgical techniques.
During CABG, cardiovascular surgeons create a 'bypass" around obstructions or blockages in affected coronary arteries by performing grafts with veins or arteries from the chest, leg or arm. The graft goes around the clogged or blocked arteries, restores the normal flow of oxygen-rich (red) blood to the heart muscle and improves cardiac function.
People who undergo traditional CABG require open heart surgery. Typically, patients are placed on a heart-lung machine which allows cardiovascular surgeons to stop the heart, make any necessary repairs and complete the bypass surgery.
Hybrid revascularization is an approach that takes advantage of stenting (angioplasty) of some blocked coronary arteries in combination with CABG surgery. The term minimally invasive heart surgery is used to describe a variety of approaches that reduce the trauma of surgery and speed recovery. This approach includes several small incisions instead of traditional open-heart CABG that requires a large median chest incision. The hybrid CABG represents an alternative to traditional bypass surgery for certain patients.
Robotically assisted coronary artery bypass (CABG) surgery is a type of minimally invasive heart surgery performed by cardiothoracic surgeons. In this procedure cardiovascular surgeons use robotic surgical devices to perform certain parts of the procedure. Because robotically-assisted CABG is minimally invasive it requires smaller incisions which allows patients to heal faster, shortens hospital stays, reduces the likelihood of infection and allows them to return to normal activity sooner as compared with traditional CABG surgery.
In the hybrid robotically-assisted procedure, the robotically-assisted surgical procedures are used in combination with coronary artery stenting to perform minimally invasive CABG surgery.
