Table 3 ΔP RA and IE outcomes

From: Right atrial pressure alterations during echocardiography-guided-catheterization predict tricuspid valvular impairment: a novel method for the creation of a rabbit model of Staphylococcus aureus endocarditis

Experimental design Group A (n = 45) Group B (n = 45)
1 × 105 CFU 1 × 104 CFU
  No-IE Faint IE Severe IE No-IE Faint IE Severe IE
ΔPRA (0–5 mmHg) 12/15 (80%) 3/15 (20%) 0/15 (0%) 14/15 (93.3%) 1/15 (6.7%) 0/15 (0%)
ΔPRA (5–10 mmHg) 0/15 (0%) 14/15 (93.3%) 1/15 (6.7%) 12/15 (80%) 3/15 (20%) 0/15 (0%)
ΔPRA (10–15 mmHg) 0/15 (0%) 4/15 (26.7%) 11/15 (73.3%) 10/15 (66.7%) 5/15 (33.3%) 0/15 (0%)
  1. No-IE: Did not develop IE by echocardiography or by histologic findings; Faint IE: Infectious endocarditis could confirmed by histologic findings but not visualized by echocardiography; Severe IE: Infectious endocarditis confirmed by both echocardiography and histologic findings. LV: Left ventricle; RV: Right ventricle; V TR : Peak velocity of tricuspid valve regurgitation; ΔP RA : Right atrial pressure before and just after valvular impairment was used to calculate alterations of right atrial pressure, indicated as ΔPRA.
