Signs of Pulmonary Hypertension vs Right Heart Failure
Pulmonary hypertension
Palpable RV heave and S2
LoudH2
S4 present
Pulmonary flow murmur
Right heart failure
ElevatedJVP
S3 present
Peripheral oedema, ascites, pleural effusions
Diagnostic Catheterization
fluid loading may unmask latent pericardial constriction afterload reduction or inotropic stimulation may be used to increase the outflow tract
gradient in HCM
coronary vasoreactive agents (e.g. methylergonovine, acetylcholine)
a variety of pulmonary vasoreactive agents in primary pulmonary HTN (e.g. oxygen,
calcium channel blockers, adenosine, nitric oxide, or prostacyclin)
