| Table A: Echocardiographic probability of PH in symptomatic patients with a suspicion of PH | ||
| Peak tricuspid regurgitation velocity (m/s) | Presence of other echo "PH signs"* | Echocardiographic probability of PH |
| ≤2.8 or not measurable | No | Low |
| ≤2.8 or not measurable | Yes | Intermediate |
| 2.9 to 3.4 | No | |
| 2.9 to 3.4 | Yes | High |
| >3.4 | Not required | |
| Table B: Additional echocardiographic signs suggestive of PH | ||
| A: The ventricles¶ | B: Pulmonary artery¶ | C: IVC and RA¶ |
| RV/LV basal diameter/area ratio >1.0 | RVOT AT <105 ms and/or midsystolic notching | IVC diameter >21 mm with decreased inspiratory collapse (<50% with a sniff or <20% with quiet inspiration) |
| Flattening of the interventricular septum (LVEI >1.1 in systole and/or diastole) | Early diastolic pulmonary regurgitation velocity >2.2 m/s | RA area (end-systole) >18 cm2 |
| TAPSE/sPAP ratio <0.55 mm/mmHg | PA diameter >AR diameter PA diameter >25 mm | |
PH: pulmonary hypertension; PA: pulmonary artery; IVC: inferior vena cava; RA: right atrium; RV: right ventricle; LV: left ventricle; RVOT AT: right ventricular outflow tract acceleration time; LVEI: left ventricle eccentricity index; TAPSE: tricuspid annular plane systolic excursion; sPAP: systolic pulmonary arterial pressure; AR: aortic root.
* Refer to Table B.
¶ Echocardiographic signs from at least 2 categories (A/B/C) must be present to alter the level of echocardiographic probability of PH.آیا می خواهید مدیلیب را به صفحه اصلی خود اضافه کنید؟
