✦ Synopsis

In the management of mitral stenosls, similar long-term results can be obtained by using either an Inoue balloon catheter or a doubleballoon technique for percutaneous balloon valvuloplasty. There have been few reports concerning any deformity of an lnoue balloon.

From January 1988 to June 1995, 263 procedures of either mitral or tricuspid valvuloplasty have been performed in this center. The lnoue balloon catheter technique was used for 245 procedums. A deformity of the lnoue balloon catheter was noted in 4 (1.6%) and actual rupture of deformed balloon o c c u r d In one (0.4K). All deformltles were found at the dlstal portlon of the lnoue balloon. Valvular lnsufflclency became more severe after valvuloplasty In two c a m . Following rupture of the balloon, netther arterial embollzatlon nor perforatlon of the cardiac chambers developed. In conclusion, a deformity of the lnoue balloon, although rare, can develop during percutaneous balloon valvuloplasty. The deformity may portend balloon rupture If additional maximal dilatations are undertaken. o 1086 wlky-u~. IW.
