In January 2014, the results of a study by D. Ramzy et al. titled “Three hundred robotic-assisted mitral valve repairs: the Cedars-Sinai experience.” in Journal of thoracic and cardiovascular surgery that evaluated the relative safety and efficacy of robotic-assisted surgery for the repair of the heart’s mitral valve.

The surgeries evaluated in this study were 300 consecutive ones performed between June 2005 and October 2012 at a single center.  The 300 patients were divided into two groups based on the time of surgery, to determine the learning curve of surgeons at Cedars-Sinai.  There were 120 patients in the first, “initial” cohort, and 180 patients in the second, “recent” group.

Doctors write “Overall, 8 patients (2.7%) required subsequent mitral valve replacement via a median sternotomy” and “One patient in each group had mitral valve re-repair through a right mini-thoracotomy, and 1 patient in the first group required a mitral valve replacement via a mini-thoracotomy during the original procedure.”

The team continues “Follow-up echocardiography for the last 180 patients from 1 month to more than 1 year showed no/trace mitral regurgitation in 64.6% of patients and mild mitral regurgitation in 23.1% of patients. Seven patients (10.8%) had moderate mitral regurgitation, and 1 patient (1.5%) had severe mitral regurgitation.”  That is, at least about 35% of patients faced mitral regurgitation after robot-assisted surgery — surgery that was intended to close the mitral valve failed and blood was allowed to flow through in the opposite direction (regurgitation).

Due to the fact that a high rate of complications is associated with robotic-assisted surgery, and manufacturers such as Da Vinci have failed to warn patients and doctors and require (not merely “recommend”) training before using their devices in a clinical setting, a number of robotic-assisted surgery lawsuits have been filed.
