Event Description
|
A journal article titled - stent underexpansion due to heavy calcification in a patient with recent acute coronary syndrome successfully treated with lithotripsy - was submitted for review.This article is a case study of a patient who presented to hospital with acute coronary syndrome.Coronary angiography (ca) of the right coronary artery (rca) revealed an edge in-stent restenosis of a previously implanted stent, with heavy calcifications in the arterial wall.The lesion was crossed with a non-mdt guidewire to the distal segment of the rca.Due to the unsuccessful attempts of pre-dilation with a non-mdt balloon the buddy wire technique was used.Then sequential inflations were done with three non-mdt semi-compliant balloons.The residual stenosis remained at around 70%¿80%.A high pressure non-mdt balloon was then inflated up to 40 atm with no success.Despite the use of the buddy wire technique and a non-mdt guide extension catheter, a non-mdt drug eluting stent (des) did not reach the distal segment of the artery.The patient was qualified for lithotripsy.Lithotripsy with a non-mdt device and a catheter balloon with 4¿6 atm was performed.This enabled the final optimization of stent expansion using a 4.0 × 20 mm medtronic nc solarice balloon catheter with 22 atm.Dissection of the coronary artery wall behind the stent was found and required a non-mdt stent to be implanted.Stent optimization was performed using a 4.0 × 20 mm nc solarice balloon catheter with 8-20 atm.Control ca and optical coherence tomography (oct) showed an acceptable effect of the pci within the rca.Please note that this device (nc solarice) is not marketed in the united states; however, the device is deemed the same as the united states marketed device (nc euphora).
