Table 5. Echocardiographic criteria for screening of high-risk patients for pulmonary hypertension, if available.

Likelihood for PH	Criteria	Level of Evidence
PH unlikely	TRV ≤ 2.8 m/s, and sPAP ≤ 35 mmHg, and No additional echocardiographic criteria for PH, and Asymptomatic	B
PH possible	Criteria A • TRV ≤ 2.8 m/s, and • sPAP ≤ 35 mmHg, and	C
	• Presence of additional echocardiographic criteria for PH, or symptoms suggestive for PH Criteria B • TRV 2.9 - 3.4 m/s, or • sPAP 36 - 45 mmHg	C
PH likely	• TRV > 3.4 m/s, or • sPAP > 45 mmHg	B
