Correction to h6 based on additional information received.The valve model number and delivery system are unknown, however, in this case edwards novaflex and delivery system with sapien xt valve was only indicated for the pulmonic position replacement at the time of the original implantation, so edwards novaflex and delivery system with sapien xt valve's ifu was reviewed.Based on this review, there were no deficiencies were identified.During the manufacturing process, all sapien xt valves are 100% visually inspected for defects and 100% tested for proper coaptation under physiological backpressure conditions prior to release for distribution.Therefore, it is highly unlikely that a manufacturing defect or device malfunction contributed to the event.As noted, 'patient history tetralogy of fallot with membranous pulmonary valve atresia status post repair with patch closure of ventricular septal defect and right ventricle to pulmonary artery homograft'.It is well known that patient with prior history of tetralogy of fallot, which could increase the risk of pulmonary valve stenosis.As such, available information suggests that patient factors (tetralogy of fallot) may have contributed to the reported event.Complaint histories for all reported events are reviewed against trending control limits monthly, and any excursions above the control limits are assessed and documented as part of this monthly review.No corrective or preventative actions are required.
