Bioprosthetic valve fracture
WebDec 7, 2024 · Bioprosthetic valve fracture (BVF) has emerged as a novel technique to prevent PPM. It involves high-pressure inflation of a non-compliant balloon to fracture the ring of the BPV, allowing for further expansion of the implanted transcatheter heart valve (THV) and thereby reducing residual transvalvular gradients. ...

WebFeb 19, 2024 · In certain situations, a valve-in-valve (VIV) procedure may result in suboptimal results (excessive post-procedural mean pressure gradient) due to small internal diameter of the stenosed prosthetic surgical valve. In these cases, bioprosthetic valve annular fracture or stretching (BVF or BVS) has been described in recent years. WebBioprosthetic valve fracture (BVF) is a method to facilitate ViV TAVR in which the surgical valve ring is fractured with high-pressure balloon inflation, allowing for more optimal THV expansion, thus significantly …
