“…Goksin et al reported that approximately half of the patients in whom the guidewire or GC (contrast, balloon, or IVUS) was difficult to remove during PCI underwent surgery, and there are scattered reports of surgical procedures both in Japan and overseas [ 8 ]. To the best of our knowledge, there have been no case reports of shaft rupture of a trapping balloon or similar case reports of shaft ruptures of ultrahigh-pressure balloons [ 9 ] or IVUS ruptures [ 10 ]. Since November 2016, the balloon length has varied from 10 to 15 mm.…”

The balloon trapping technique is frequently used during percutaneous coronary intervention, which is a common treatment for ischemic heart disease. A 68-year-old man with induced ischemia, stenotic lesions, and arterial calcifications underwent catheterization of the circumflex artery and debulking of lesions. During the removal of the catheter, the tip of the balloon catheter used in the procedure dislodged and entered the circumflex artery. After successfully retrieving the catheter, we conducted a bench test of the balloon catheter to determine the cause of the tear. The results suggested that the tearing of the KUSABI balloon might have been caused by manual pulling of the shaft quickly at an inflation pressure of 14 atm and that twisted wires were not involved in balloon tearing. The tensile strength of the balloon catheter was 5N. We believe that the balloon tore owing to excessive force applied to dislodge the tip and because the trapping balloons were not properly deflated. As KUSABI trapping balloons have had a rupture rate of just 0.003% since their launch in 2013, we recommend paying attention to KUSABI balloon deflation within the guiding catheter before its retrieval in order to ensure that only a gentle pull is needed. If resistance is felt during the removal of the KUSABI balloon, it should be confirmed that the tip is in place after removing it.
