H6: medical device problem code 1494 - indication for use.The device was not returned for analysis.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.A review of similar incidents is not required.Reportedly, the guide wire was used in a cardiomems procedure resulting in hemorrhage/hemoptysis.It should be noted that the hi-torque guide wires instructions for use (indications for use section) states: ¿all hi-torque guide wires are intended to facilitate the placement of balloon dilatation catheters during percutaneous transluminal coronary angioplasty (ptca) and percutaneous transluminal angioplasty (pta).¿ in this case, it is unlikely the guide wire contributed to the reported patient effect.The investigation determined the reported patient effects and subsequent treatment appear to be related to the operational context of the procedure.In this case, it was reported that the steelcore guide wire was used in a cardiomems procedure.The details of this case were examined by a medial specialist, they determined that the guide wire was likely not responsible for the reported patient effect of hemorrhage/hemoptysis.The cardiomems instructions for use (ifu) states hemoptysis is a potential adverse event associated with the implantation procedure.Additionally, the steelcore guide wire is not indicated for use in pulmonary arteries; as such, hemoptysis is not listed as a potential adverse event in the steelcore guidewire ifu.There is no indication of a product quality issue with respect to manufacture, design, or labeling.Medical review performed stated: this was a cardiomems hf sensor implant case in a 72-year-old female patient.This was an off-label use of the steelcore guidewire used to implant the cardiomems heart failure (hf) pa sensor system.The hemoptysis was seen after the cardiomems was implanted.The cardiomems instructions for use (ifu) state that hemoptysis is a potential adverse event that was seen in multiple clinical studies.The steelcore wire is not indicated for use in the pulmonary arteries (pa); as such hemoptysis is not listed as a potential adverse event in the steelcore guidewire ifu.Additionally, it was reported that there were no issues with the steelcore guidewire during the procedure, though the physician stated that they thought the steelcore guidewire caused a perforation in the pulmonary artery.It is possible that the steelcore wire could have caused a perforation in the pulmonary artery, however, it is likely that the patient would have experienced more severe adverse events than hemoptysis if their pulmonary artery had been perforated.Several possible mechanisms can cause pa injury and cause hemoptysis in patients undergoing cardiomems implantation.The most common cause of injury is the migration of the catheter's nose cone or wire.3 in addition, pa walls of patients with hf are friable and more prone to injury due to the fragmentation of the internal elastic lamina and deposition of disorganized extracellular matrix.3 the type of wire used for selecting pulmonary arteries can have a bearing on the risk of iatrogenic injury.For example, non-abbott hydrophilic coated guidewires are notorious for causing dissections and perforations if the physician does not respond adequately to the tactile feedback during the procedure.4 due to the information provided, it can be definitively stated that the cardiomems device was the most likely cause of this patient's hemoptysis.However, though it cannot be definitively stated that the steelcore guidewire was the direct cause of the hemoptysis, it may have been a contributing factor.H6: health effect - impact code 4650 removed; 1888 added.H6: medical device problem code 2993 removed; 1494 added.
