It was reported that the procedure was performed to treat an unspecified lesion.The trek balloon dilatation catheter (size not specified) had a hole in the shaft.The hole in the shaft caused air to enter the patient.Treatment, if any, was not reported.There was no adverse patient sequela reported.Subsequent to the initially filed report, the following information was received: it was reported that the procedure was performed to treat a moderate to heavily calcified and non-tortuous right coronary artery (rca).The 2.0x12mm mini trek balloon failed to inflate.The device was removed and inspected.A hole was found in the shaft.The hole in the shaft caused air to enter the patient.The air caused no reflow in the posterior lateral branch of the rca due to air embolism as well as elevated st and mild chest pain.The patient was treated with additional ballooning.A new trek balloon was used to successfully complete the procedure.There was no adverse patient sequela reported.No additional information was provided.

Visual and functional inspections were performed on the returned device.The reported tear and inflation issue were confirmed.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history of the reported lot did not indicate a lot specific quality issue.The reported patient effects of air embolism and angina are listed in the coronary dilatation catheters (cdc), trek rx and mini trek rx, global, instructions for use as known patient effects.The investigation determined the reported tear, inflation issue and additional treatment appear to be related to operational context.A conclusive cause for the reported patient effects of air embolism, angina and st elevation (ekg/ecg changes) and the relationship to the device, if any, cannot be determined.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.B3: date of event changed from (b)(6) 2021 to (b)(6) 2021.
