DR JOHN W. BROWN (Indianapolis, IN): This robotic technology has obviously advanced very quickly. Can you tell me what the clinical experience is with robotics as far as mitral valve surgery is to date at your institution?

DR LAPIETRA: At our institution we are currently using a robotic arm to control the videoscopic camera for cardiac procedures. The robotic instrumentation is currently in cadaver studies and, later this spring, will be starting clinical trials. However, there is vast experience in Europe, especially in Germany, for biotechnology for cardiac surgery as this equipment has been released earlier in Europe.

DR JENNIFER ELLIS (La Jolla, CA): My question is, compared to a minimally invasive surgery, what size incisions do you end up using and what is the total size of the incision? So basically, where do you see the benefit of this procedure for mitral valves?

DR LAPIETRA: It is a good question. Thank you for your comment. The incision that we use, as I mentioned, is approximately a 3-cm incision, just enough to pass the atrial retractor and parachute the sutures down, and then we used a knot pusher to tie our knots.

In our institution, we have a very large experience with minimally invasive mitral valve surgery. This basic science study was a feasibility study prior to beginning clinical trials. We have not yet answered the question as to what is the value-added benefit to this technology. We are currently planning to evaluate it clinically and, hopefully, it will enable us to make further advances in minimizing trauma to patients who need to undergo cardiac surgery.
