Interventions/Control_1

After qualification, the subjects are assigned 1: 1 ratio to the furosemide continuation group or tolvaptan administration group. Furosemide continuation group will continue the preoperative dose.

Interventions/Control_2

For tolvaptan administered group, substitution of furosemide 20 mg / day orally before TAVI surgery, with tolvaptan at 3.75 mg / day after surgery. In the case of furosemide 40 mg / day oral administration, administration was started by substituting tolvaptan 7.5 mg / day after surgery. Continue until outpatient visit one month after surgery.
