ABSTRACT
PURPOSE OF REVIEW This review aims to summarize data regarding bioprosthetic valve fracture (BVF), a novel technique that involves fracturing the surgical valve sewing ring to allow for further expansion of the transcatheter heart valve in patients undergoing valve in valve transcatheter aortic valve replacement (VIV TAVR). RECENT FINDINGS:
Bench testing and clinical experience have demonstrated that most, but not all, bioprosthetic surgical valves can be fractured. BVF in patients with small- and intermediate-sized surgical valves results in a lower residual valve gradient and larger final valve effective orifice area as compared with standard VIV TAVR. However, whether patients with larger bioprothetic valves benefit from BVF, and whether the hemodynamic benefits of BVF translate into improved clinical outcomes, is unknown. BVF improves the hemodynamic results of VIV TAVR in small surgical valves. However, further research is needed to determine whether BVF is beneficial for patients with larger surgical valves, and whether the hemodynamic benefits of BVF result in improved clinical outcomes.Palabras clave
