Event Description

Medtronic received information that during the implant of this 27mm mitral mechanical valve, it was explanted and replaced with a 27mm mechanical valve of a different manufacturer.The reason for the replacement was reported as a leaflet was not coapting properly as it was observed during a final transesophageal echocardiogram (tee) that there was a leak in the center of the valve. a check was performed to determine a possible cause for this but the valve was observed to be properly implanted.It was noted by the physician that "the gap on the coaptation of the leaflets" could not be seen with the naked eye but the central leak could be observed using tee.It was also reported that the valve was rotated within the annulus but the leak still persisted.It was stated that leaflet motion was tested with the blue actuator during the implant procedure.It was mentioned that there was no impingement of the valve leaflets.It was stated that the valve was replaced to ensure patient safety.No additional adverse patient effects were reported. .
