This study aimed to investigate the efficacy of percutaneous transcatheter aortic valvuloplasty (PTAV) performed prior to non-cardiac surgery and the safety of non-cardiac surgery after PTAV in elderly Japanese patients. Between March 2012 and August 2018, 14 patients who underwent PTAVs prior to non-cardiac surgery were enrolled. The mean age was 82.2 ± 7.0 years. A total of 9 patients (64.3%) were women. A retrograde approach was selected for 57.1% of the patients. More than 75% of the procedures were performed using echocardiographic imaging. Echocardiographic data including the aortic valve area (AVA), peak aortic valve blood velocity flow (AVF), peak aortic valve pressure gradient (AVPG), and mean AVPG significantly improved after PTAV (AVA; from 0.54 ± 0.11 to 0.80 ± 0.13 cm 2 , peak AVF; from 4.6 ± 0.8 to 3.8 ± 0.7 m/s, peak AVG; from 87.9 ± 28.0 to 62.2 ± 19.9 mmHg, mean AVG; from 49.8 ± 18.9 to 35.7 ± 11.6 mmHg; p
