Manufacturing review: a manufacturing review was not requested as the lot number reported as unknown.Investigation summary: the physical device was not returned for evaluation.Two fluoroscopic images and six photos are provided and reviewed.The first image (1a) shows a 24-mm true balloon inflated inside the 27-mm mosaic valve.The second image (1b) shows a femoral venogram demonstrating a filling defect in the right common iliac vein.The third photo (1c) shows the surgical view of the degloved true balloon in the right common iliac vein.The fourth photo (1d) shows the true balloon had been degloved and separated from the shaft of the balloon catheter.The fifth photo (2a) shows a true balloon inflated on a straight segment of wire.The sixth photo (2b) shows complete balloon rewrap on the straight segment of wire.The seventh photo (2c) shows a true balloon inflated on a curved segment of wire.The eighth photo (2d) shows incomplete balloon rewrap when deflated on a curved portion of the wire.The investigation is confirmed for the reported break as photos 1b, 1c and 1d show the break noted on the balloon.The investigation is also confirmed for the reported failure to fold and deflation problem as photo 2d shows the balloon not deflating to the correct folded profile.The investigation is also confirmed for the reported retraction problem as the break in the balloon would lead to difficulty removing the device.A definitive root cause for the alleged break, deflation problem, retraction problem and failure to fold could not be determined based upon the provided information.Labeling review: a review of product labeling documentation (e.G., procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) did not find any product labeling inadequacy.Andrew g.Chatfield, mariama akodad, david meier, ming-yu (anthony) chuang, janarthanan sathananthan, david a.Wood, et.Al (2022).Failure of complete rewrap of a noncompliant valvuloplasty balloon complicating a transcatheter valve-in-valve procedure.Journal of the american college of cardiology, 15 (7): e81-e83.Doi: https://doi.Org/10.1016/j.Jcin.2022.02.020.Device not returned.
