Figure 3: Invasive Hemodynamics Were Unchanged After Pericardial Gel Placement

The right atrium is the lowest pressure cardiac chamber with the thinnest wall and most susceptible to compression from increased pericardial pressure. (A and B) Right atrial pressure and left ventricle end-diastolic pressure did not change in pigs in the immediate post-procedure period or after 4 to 6 weeks (n = 8; error bars ± SD). (C) Simultaneous left and right ventricle pressure showed no accentuated respiratory variation and no ventricular interdependence (paper speed 25 mm/s, representative image).
