A 91-year-old woman with severe aortic stenosis was referred for transfemoral transcatheter aortic valve implantation (TAVI). Multi-detector computed tomography imaging revealed severe calcification at the non-coronary cusp (NCC) (Figure 1A-C). After placing a Safari2 (Boston Scientific, Marlborough, MA, USA) small curve wire in the mid-left ventricle (LV), balloon aortic valvuloplasty (BAV) was performed using VACSII 16×40 mm (OSYPKA, Rheinfelden, Germany) (Figure 1D). A SAPIEN 3 (Edwards Lifesciences, Irvine, CA, USA) 23 mm was unable to cross the aortic valve (AV) (Figure 1E). Changing bias by pulling or pushing the Safari2 wire or flexing the Commander delivery system (Edwards Lifesciences) did not allow the transcatheter heart valve (THV) to pass. Consequently, we inserted another stiff wire (EGoist; Asahi Intecc, Nagoya, Japan) into the LV via contralateral femoral artery, and performed repeat BAV (Figure 1F); however, the THV system did not cross. Then, we repeated BAV while simultaneously pushing the THV during balloon deflation. The system was successfully slipped over the AV (Figure 1G, Supplementary Video 1), and the SAPIEN 3 was implanted (Figure 1H).
