Lessons learned from balloon aortic valvuloplasty experience from the pre-transcatheter aortic valve implantation era.

摘要

BACKGROUND: Balloon aortic valvuloplasty (BAV) has been used as a bridge to surgical aortic valve replacement (SAVR) in high-risk patients with severe symptomatic aortic stenosis (AS). Such patients are now being referred for transcatheter aortic valve implantation (TAVI). We sought to study the indications and outcomes of BAV in patients with severe AS in the pre-TAVI era. METHODS: We analyzed consecutive patients with severe AS undergoing BAV from 1990 to 2005. In these patients with no immediate surgical option, BAV was attempted to temporarily improve hemodynamics, with a goal to improve general health of the patient, and ultimately AVR. RESULTS: A total of 99 BAVs (eight repeats, one second repeat) were performed in 90 consecutive patients. Baseline ejection fraction was
