In this series of patients, one stroke occurred 2 days after the procedure, but there were no deaths in the initial 30-day follow-up, according to Dr. Webb. Although he noted that the procedure time in the first case was 4 hours, the procedure times became shorter with experience and the second-to-last and last cases took 2.5 and 1.3 hours, respectively.
Howard C. Herrmann, MD, director of the interventional cardiology program at the University of Pennsylvania, Philadelphia, and a panelist on the symposium where these data were presented, called the results “exciting.” However, he also noted that “this is the first time that any us have had a look at this device,” so more data will be needed to understand its clinical potential.
Edwards Lifesciences sponsored this study. Dr. Webb reported financial relationships with Abbott Vascular, Edwards Lifesciences, Essential Medical, and Vivitro.
