Totally endoscopic coronary artery bypass surgery
Totally endoscopic coronary artery bypass surgery (TECAB) is an entirely endoscopic robotic surgery used to treat coronary heart disease, developed in the late 1990s. It is an advanced form of minimally invasive direct coronary artery bypass surgery, which allows bypass surgery to be conducted off-pump without opening the ribcage.
