Table 1 Hemodynamic parameters at diagnosis showing a significant left-to-right shunt with elevated right-sided pressures and pulmonary vascular resistance consistent with pulmonary hypertension.
| Parameter | Value | Reference range/normal value |
|---|---|---|
| Left-to-right shunt ratio (Qp: Qs) | 2: 1 | ~1: 1 |
| Right ventricular systolic pressure | 101 mmHg | 15–30 mmHg |
| Pulmonary blood flow (Qp) | 8.79 L/min | ~4–6 L/min |
| Pulmonary vascular resistance (PVR) | 5.2 Wood units | 0.25–1.6 Wood units |
