Opacification of the right chambers after four cardiac cycles (positive test for intrapulmonary vascular dilatations). 1 Table 1 – Demographic and clinical characteristics of patients with hepatosplenic schistosomiasis (HSS) Age (years) 51.8 ± 8.4 (41-66) Sex 10 men 9 women Body surface (m 2 ) 1.72 ± 0.14 (1.56 - 2.07) Heart rate (bpm) 73 ± 16 (51-106) SBP (mmHg) 139 ± 20 (105-178) DBP (mmHg) 83 ± 15 (60-113) Hemoglobin (g/dl) 13.7 ± 2.4 (8.9-18.8) Hematocrit (%) 41.1 ± 5.3 (30.6-48.1) Platelets (mil/mm 3 ) 94.843 ± 60.391 (25.000-281.000) Albumin (g/dL) 4.43 ± 0.40 (3.9-5.3) AST (U/L) 34.8 ± 10.1 (24-59) ALT (U/L) 31.5 ± 13.5 (17-77) Alkaline phosphatase (U/L) 94 ± 26 (67-161) INR 1.2 ± 0.18 (1.01-1.5) PaO 2 (mmHg) 80.2 ± 9.1 (60-97) PaCO 2 (mmHg) 36.7 ± 4.7 (28-45) SatO 2 (%) 95.8 ± 1.59 (94-98) A-aO 2 (mmHg) 10.9 ± 7.5 (2.63-26.68) Values expressed as mean and standard deviation (variation range in parentheses). SBP: systolic blood pressure; DBP: diastolic blood pressure; AST: aspartate transaminase (U/L); ALT: alanine transaminase (U/L); INR: international normalized ratio; PaO 2 : partial oxygen pressure; PaCO 2 : partial pressure of carbon dioxide; SatO 2 : blood oxygen saturation; A-aO 2 : alveolar-arterial gradient. In the control group, 12 (65%) individuals showed grade I in the contrast test, and the other seven showed grade 0. Therefore, grade I was considered the normal response to the CTEE, and only contrast test results classified as grades ≥II in cTEE were considered positive for IPVD in the HSS group. Comparison between cTEE and cTTE for IPVD diagnosis is described in Table 2. At cTEE, 13 patients (68%) with HSS had a positive test for IPVD, one with grade III (moderate) and 12 with grade II (mild). No patient showed significant contrast enhancement. At cTTE, the appearance of contrast in the left chambers was detected in only four (21%) patients with HSS (p < 0.01 versus cTEE). A negative test for IPVD was found in six patients according to bothmethods (cTTE and cTEE), with contrast test grade I for five patients at cTEE, whichwas considered normal. 917
