Plasma levels of brain natriuretic peptide (BNP) have been shown to correlate to aortic
stenosis severity and are predictive of symptom development and survival. They also
predict postoperative outcomes after valve replacement in patients with aortic stenosis.
The early evolution of N-terminal–pro-BNP (NT–pro-BNP) levels after 50 aortic balloon
valvuloplasty procedures performed in 45 patients was investigated. The mean NT–pro-BNP
concentration decreased from 7,048 ± 7,636 pg/ml at baseline to 5,309 ± 6,150 pg/ml
at 1 to 3 days after the procedure (mean difference 1,739 pg/ml, 95% confidence interval
804 to 2,675, p = 0.001). The absolute reduction in NT–pro-BNP levels correlated to
the reductions in the maximum and mean transvalvular pressure gradients (on echocardiography:
c = 0.57, p = 0.004, and c = 0.54, p = 0.012, respectively; invasively: c = 0.54,
p = 0.025, and c = 0.39, p = 0.019). In conclusion, NT–pro-BNP levels decrease early
after aortic balloon valvuloplasty in patients with severe aortic stenosis at high
surgical risk.
