I recently received an interesting question from Emily about her upcoming aortic valve replacement.

Emily writes, “Hi Adam – After years of monitoring it, my aortic stenosis is now severe ^[1] and I need a valve replacement. Yes. I’m scared. Yes. I’m confused. One thing I’m both scared and confused about is the cracking of my chestplate. Is it true that AVR can be done with smaller incisions to the sternum? If so, is that common?”

Mini Sternotomy Scar (3-inch Incision)

In case you are not familiar with the term, Emily is referring to a mini-sternotomy which utilizes a significantly smaller incision than a full, median sternotomy (which I had).

According to Brigham & Women’s Cardiovascular Center in Boston, Massachusetts:

• Mini-Sternotomy for aortic valve replacement incisions ^[2] are performed through an upper mini-sternotomy, in which an incision is made from the sternal notch to the third intercostal space.
• Mini-Sternotomy for mitral valve replacement ^[3]/repair incisions are performed through a lower mini-sternotomy, in which a 6-8 cm incision is made at the lower end of the sternum upward to the second intercostal space and extending into the interspace on the right.

So you know, my broken sternum incision ^[4] is about 9 inches long. A mini-sternotomy incision is about 3 to 4 inches long. Ultimately, the benefits of a mini-sternotomy are less trauma to the chestplate and faster recovery.

As for Emily’s second question, “Are mini-sternotomy procedures common?”, I contacted Dr. Eric Roselli, a cardiothoracic surgeon from the Cleveland Clinic ^[5] to learn more. According to Dr. Roselli, “Almost all isolated first time aortic valves get a mini-sternotomy in my practice and I believe that’s true for my colleagues as well.”

I hope this helps Emily (and perhaps you) learn a little more about the difference between mini- and full-sternotomy.

Keep on tickin!
