The patients were divided into two groups (no BPD\u2010period and BPD\u2010period). Before BPD, RAoR \u2265 2 was seen in 25% of the patients in group 1 and in 29% of the patients in group 2 (<jats:italic>P<\/jats:italic> \u2265 0.593). BPD was carried out in 95% (<jats:italic>n<\/jats:italic> = 21) of the patients in group 2 with RAoR \u2265 2. Regurgitation improved one grade in 68% of the cases (<jats:italic>n<\/jats:italic> = 15), 2 grades in 14% (<jats:italic>n<\/jats:italic> = 3), and remained without change in 18% (<jats:italic>n<\/jats:italic> = 4). RAoR &lt; 2 was achieved in 91% (<jats:italic>n<\/jats:italic> = 73) of the patients in group 2 versus 75% (<jats:italic>n<\/jats:italic> = 58) in group 1 (RR = 0.35, 95% CI 0.16\u20130.80, <jats:italic>P<\/jats:italic> = 0.013). We recorded no aortic ring ruptures, damage to the device or displacements. Slight central regurgitation not present before BPD was registered in one case.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>BPD offers a very good safety profile and reduces RAoR in a large percentage of cases.
