Hemodynamic criteria for repair of cardiac defects with pulmonary arterial hypertension.

Table 2: Hemodynamic criteria for repair of cardiac defects with pulmonary arterial hypertension.

Conduct	Criteria	Absolute RVP
Repair	PVRI < 4 WU/m² PVR/SVR ratio < 0.5	PVR < 2.3 WU
No repair	PVRI > 8 WU/m² PVR/SVR ratio > 0.5	< 4.6 WU
Pulmonary vascular vasoreactivity test	PVRI 4-8 WU/m² PVR/SVR ratio > 0.5-0.3	2.3-4.6 WU
