Case 178: Manual of PCI - In-stent undilatable lesion

Описание к видео Case 178: Manual of PCI - In-stent undilatable lesion

A patient with prior mechanical AVR and CABG and cardiomyopathy presented with angina. The LIMA to LAD was occluded and the culprit lesion appeared to be a 90% mid LAD in-stent lesion. The lesion would not expand despite inflating a 3.0 mm NC balloon at 26 atm. Intravascular lithotripsy with 100 pulses and very high pressure SIS-OPN balloon inflation at 50 atm also failed to expand the lesion. Surprisingly, subsequent inflation of a 3.0 mm Scoreflex expanded the lesion with a nice final result after implantation of an additional DES.
