Figure 3 Effect of annuloplasty device on left ventricular (LV) volumes and hemodynamics. Above are shown LV pressure-volume loops before (black) and after (red) cinching of the device and the corresponding LV and left atrial (LA) pressures. Below are LV pressure-volume loops and LV and LA pressure tracings before and after cinching of the device during phenylephrine (PE) infusion. ECG = electrocardiogram.
