Objectives

The objective was to demonstrate that mitral balloon valvuloplasty (MBV) with single balloon, the less expensive technique, has similar outcome and long-term follow-up (FU) than MBV performed with the Inoue worldwide-accepted technique.

Methods

From 1987 to December 31, 2009, a total of 525 procedures were performed, with 311 having long-term FU of 51±33 (1–174) months, 55 (17.7%) with Inoue balloon (IBG) FU 33±27 (2–118) months and 256 (82.3%) with single balloon (SBG) FU 55±33 (1–174) months ( P <.0001). Multivariate Cox analysis was utilized to determine independent predictors of survival and event-free survival (EFS). Major events (ME) were (death, cardiac surgery and new MBV).
