Abstract:
Valve-in-valve transcatheter aortic valve replacement (VIV TAVR) has emerged as a preferable option for high surgical risk patients requiring redo aortic valve replacement. However, VIV TAVR may restrict flow, especially in small native aortic valves. To remedy this, bioprosthetic valve fracture has been utilized to increase the effective orifice area and improve hemodynamics. We present three cases in which bioprosthetic valve fracture was used to increase hemodynamic flow in VIV TAVR procedures.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
