Heart bypass surgery - minimally invasive - Overview

Alternative Names

Minimally invasive direct coronary artery bypass; MIDCAB; Robot assisted coronary artery bypass; RACAB; Keyhole heart surgery

Definition of Heart bypass surgery - minimally invasive:

Heart bypass surgery creates a new route, called a bypass, for blood and oxygen to reach your heart. It helps fix problems caused by coronary artery disease (CAD), in which the arteries that lead to your heart are partly or totally blocked.

Minimally invasive coronary (heart) artery bypass can be done without stopping the heart and putting a patient on a heart-lung machine.

Description:

A heart surgeon will make a 3- to 5-inch-long incision (cut) in the left part of your chest between your ribs. This allows the surgeon to reach your heart. Muscles in the area will be pushed apart. A small part of the front of the rib, called the costal cartilage, will be removed. Then the surgeon will find and prepare an artery in your chest to attach to your coronary artery that is blocked.

Once the above steps are done, the surgeon will connect the prepared chest artery to your coronary artery that is blocked.

You will not need to be on a heart-lung machine for this surgery, but a device will be attached to your heart to slow it down.
