Answer 1

mPAP >20 mmHG!

S/S: S2 and S4 gallop hear sounds, LE swelling

28

Question 2

Pulm HTN is divided into 3 profiles based on PAWP and PVR. What are the classifications?

Answer 2

isolated precapillary PH
isolated postcapillary PH
combined pre and post capillary PH

28

Question 3

What is the definition of isolated postcapillary pulmonary hypertension?

Answer 3

• increased pulmonary venous pressure
• usually determined by elevated LAP cause by valve disease or LV dysfunction

Slide 29

Question 4

Isolated postcapillary pulmonary hypertension is characterized by?

Answer 4

• PAWP >15mmHg with a normal PVR

Slide 29

Question 5

Describe combined pre and postcapillary pulmonary hypertension?

Answer 5

• (aka reactive PH) reflects chronic pulmonary venous HTN with secondary pulmonary arterial vasoconstriction and remodeling

Slide 29

Question 6

What are the characteristics of combined pre and postcapilliary pulmonary hypertension ?

Answer 6

• PAWP >15mmHg and a PVR > 3.0 WU
• subcategorized as fixed or vasoreactive do to the response to vasodilators, diuretics, or mechanical assistance

Question 7

Describe high- flow pulmonary hypertension?

Answer 7

occurs without an elevation in PAWP or PVR and results from increased pulmonary blood flow cause by a systemic-to-pulmonary shunt or high cardiac output
