Rather than a sternotomy -- a standard approach for open-heart surgery that requires a large chest incision, dividing the breastbone, and spreading the ribs -- minimally invasive heart surgeries use an approach called mini thoracotomy. It requires one small incision between two ribs. Long, thin tools are inserted through the incision to fix the heart.
Robotic-Assisted Heart Surgery
In robot-assisted minimally invasive heart surgery, your surgeon performs the procedure by controlling robotic arms, which can further reduce incision size. In addition to the mini thoracotomy incision, several small incisions (less than about half an inch long) are placed for the robot arms. A high-powered camera magnifies your surgeon’s view of the heart to improve precision. The ribs are not spread, which reduces pain after surgery.
