Coronary Flow Velocity Before and After Transcatheter Aortic Valve Replacement

Figure demonstrating the changes in coronary flow before and after transcatheter aortic valve replacement (TAVR). The left side of the graph is resting flow over the whole cardiac cycle (PdPa-flow); the middle side of the graph is resting flow during the wave-period of diastole (iFR-flow); and the right side of the graph is hyperemic flow over the whole cardiac cycle (FFR-flow). Both PdPa-flow and FFR-flow increase significantly more post-TAVR than iFR-flow, which is constant. The bars denote mean values, with the error bars denoting SEs.
