Event or Problem Description
Subsequent to the initial filed medwatch report, additional information was received from the physician, resulting in the following revised narrative: a female patient presented for planned percutaneous coronary intervention (pci).Angiography performed on (b)(6) 2019 showed a severely calcified lesion in the ostial right coronary artery (rca) and proximal left anterior descending (lad) coronary artery.The physician gained arterial access via the right superficial femoral artery.A 4.0x30mm cobra pzf¿ nanocoated coronary stent was advanced and deployed in the proximal lad without issue.The rca lesion was prepped via atherectomy.An attempt was then made to cross the calcified ostial rca lesion with two cobra pzf¿ nanocoated coronary stent systems (3.5x30mm then a 3.5x24mm), but each stent system was unable to cross due to the severe calcification.After crossing attempt, each stent dislodged in the hemostatic valve after retraction through the 7f guide catheter.In each occurrence, the stent was retrieved from the hemostatic valve without injury to patient.A 3.5x16mm drug-eluting stent ultimately crossed and was deployed in the rca.Though requested, no additional information was provided.
