Balloon Aortic Valvuloplasty Might Be a Safe Therapeutic Option for Acute Decompensated Heart Failure Due to Severe Aortic Valve Stenosis

      Background: Acute decompensated heart failure (ADHF) due to atrial valve stenosis (AS) has been increasing in highly aging society as Japan. However, little is known regarding the usefulness of balloon aortic valvuloplasty (BAV) in AS patients with ADHF. We report the initial results of BAV in our hospital, which started from October 2016. Methods: We retrospectively analyzed the characteristics, in-hospital death and hospitalization days of AS patients admitted due to ADHF. We included 11 patients who were medically treated in October 2015 to May 2016 (G1), and 8 patients who underwent BAV in October 2016 to May 2017 (G2). Results: Female in G1 and G2 accounted for 72% and 100%, respectively. Mean age was 89.1 y.o. in G1 and 88.6 y.o. in G2. Mean aortic valve area, mean max velocity, and median BNP level in G1 and G2 were, 0.88 cm2 and 0.46 cm2, 3.3m/sec and 4.5m/sec, and 568 pg/ml and 513 pg/ml, respectively. Three patients in G1 died and two of them died at 8 days after admission, but no patients died in G2. Mean change of pressure gradient after BAV was 25.2 mmHg. Median hospitalization days of G1 and G2 were 19 days and 26.5 days, respectively. Conclusion: We had no in-hospital deaths in patients underwent BAV, suggesting that BAV could be a safe and effective therapeutic option for ADHF due to AS.
