Differentiating PAH from PVH - Echocardiography Pulmonary Artery Hypertension (PAH): • RV size - Enlarged • LA size - Small • RA/LA size ratio - Increased • Interatrial septum - Bows from right to left • RVOT notching - Common • ElA ratio << 1 • Lateral e' Normal • Lateral E/e' <8 • Aortic pressure - Normal/Low • PCWP < 15 mmHg • PADP-PCWP > 7 mmHg Pulmonary Venous Hypertension (PVH): • RV size - May be enlarged • LA size - Large • RA/LA size ratio - Normal (LA > RA size) • Interatrial septum - Bows from left to right • RVOT notching - Rare • ElA ratio > 1 • Lateral e' Decreased • Lateral E/e' > 10 • Aortic pressure - Normal/High • PCWP > 15 mmHg • PADP-PCWP < 5 mmHg Dr. Sanjiv Shah @HFpEF #Differentiating #PAH #PVH #Echocardiogram #comparison #diagnosis #cardiology #pulmonary #arterial #venous #hypertension
