Abstract

We evaluated the effect in unloading of the left ventricle with transaortic catheter venting(TACV) during venoarterial bypass(VAB). The preload recruitable stroke work(PRSW) in VAB with TACV decreased significantly than VAB only. the LV pressure-volume area (PVA) in VAB with TACV decreased significantly comparing with VAB and baseline. The potential energy (PE)/PVA, the index of the energetic charge in VAB with TACV increased significantly than baseline.So TACV was suggested to be the effectiveness of the assist device with PCPS for severe left heart failure.
