OR-Live.com presents: live heart surgical broadcast of a robotic
assisted Mitral valve repair
18 January 2005
East Carolina University cardiothoracic surgeon W. Randolph Chitwood and
his surgical team performed a mitral valve repair using the da Vinci
Surgical System during a live webcast January 18, 2005 on
Each year, more than 50,000 procedures are performed on the mitral valve,
which regulates the blood flow from the left atrium, or holding chamber, to
the left ventricle, the heart's main pumping chamber.
Chitwood and his surgical team performed the first total heart valve
surgery using robotic technology in North America in May 2000. To date, he
has performed more than 175 mitral valve repairs using the da Vinci Surgical
"During these first 176 operations, we have learned that cardiac surgery
can be done safely using robotic techniques with the same results as a full
sternotomy (full chest incision). Visualization and dexterity are much
better," Chitwood said.
Chitwood pointed out that the majority of patients have excellent
post-surgery recuperation results after minimally invasive, robotically
assisted mitral valve surgery. The average length of stay in the hospital is
less than four days compared with eight days for conventional open-heart
procedures. Most patients are back to work in 10 to 14 days.
Chitwood is professor of surgery, chief of cardiothoracic and vascular
surgery, and senior associate vice chancellor for health sciences at the
Brody School of Medicine at East Carolina University. The operation will be
performed at Pitt County Memorial Hospital, the affiliated teaching hospital
for ECU's medical school. The Webcast will be moderated by the director of
the Robotic Training Center at ECU, cardiothoracic surgeon Wiley Nifong.
The da Vinci Surgical System, developed and produced by Intuitive
Surgical, was approved by the Food and Drug Administration for its first
cardiac use (mitral valve repair) in November 2002. Chitwood served as
principal investigator for the 10-hospital FDA Phase 1 study and the
expanded Phase 2 study that led to that approval.
