We offer patients a minimally invasive procedure to treat blockages in the coronary arteries. Minimally invasive direct coronary artery bypass, or MIDCAB, requires specialized skills and intensive training.

The surgeons at the University of Maryland Heart and Vascular Center are among the few surgeons in the country performing this technically challenging procedure.

What is MIDCAB?

In an open heart bypass procedure, surgeons need to cut the chest open to access to the heart. This creates a large scar and requires a lengthy recovery period. During a MIDCAB procedure, we will:

  • Create a tiny, two-and-a-half inch opening between two ribs in the left side of the chest. 
  • Harvest an artery from the chest. We may do this directly or we may use a surgical robot. 
  • Stitch the artery to the coronary arteries through the keyhole-size opening. We perform this stitching, or suturing, while the heart is still beating, so you do not need to go on a heart-lung bypass machine.

We may combine the MIDCAB procedure with catheter-based intervention on the coronary arteries in a hybrid coronary intervention. This procedure involves stenting these right-sided blockages at the same time as the surgical bypass. Learn more about hybrid coronary intervention.
