Antegrade balloon aortic valvuloplasty (BAV) may be more effective than retrograde BAV. However, early restenosis is found inconstantly within three months after BAV. To evaluate the factor of ER after intracardiac echocardiogram (ICE) guided Antegrade BAV, fifty patients with severe aortic stenosis (AS) underwent BAV procedures with ICE. ER was defined as mean aortic valve pressure gradient (PG) >40 mmHg. During one-year follow-up period, 6 patients died and 2 patients underwent aortic valve replacement. ER was present in 13 patients (26%) at three months after BAV. Procedural, clinical, and hemodynamic data were collected. The mean age of the patient population was 85.4 ± 7.6 years; the mean STS score and EuroSCORE were 7.8 ± 1.1 and 14.6 ± 4.1, respectively. The mean aortic valve PG decreased from 63.4 ± 19.8 to 28.5 ± 10.1 mmHg ( p
