Pulmonary hypertension in aortic valve stenosis.

Trends Cardiovasc Med 2020 Dec 17. Epub 2020 Dec 17.

Cardiology Department, Kantonsspital St. Gallen, Switzerland.

In patients with severe aortic stenosis (AS), pulmonary hypertension (PH) typically is indicative of a decompensated disease state with exhausted compensatory mechanisms of the left ventricle, meaning a heart failure state resulting from AS-related "cardiac injury". In the present review article, we discuss new insights into the pathophysiology of AS-induced PH, the prognostic impact, and potential options to prevent and treat PH in this setting. We emphasize recent data from studies focused on invasive hemodynamics in patients with severe AS that are being evaluated for aortic valve replacement, particularly the key relevance of combined pre- and post-capillary PH.
