Pre- and postoperative progress. 0 month was the month of the surgery. Six months postoperatively, cardiac function improves to preoperative levels. NT-pro BNP and Cr tend to decrease with the control of heart failure, but a further decrease is observed postoperatively. PRA is high and tends to increase preoperatively. Postoperatively, it decreases. The dose of antihypertensive drugs can be reduced after the operation. In addition, diuretics used to control heart failure can be discontinued postoperatively. ARB, angiotensin II receptor blocker; Cr, creatinine; LVEF, left ventricular ejection fraction; NT pro BNP, N-terminal pro brain natriuretic peptide; PRA, plasma renin activity
