Limitations of right heart catheterization in the diagnosis and risk stratification of patients with pulmonary hypertension related to left heart disease: Insights from a wireless pulmonary artery pressure monitoring system

Using only RHC, World Health Organization group II PH may be significantly under-diagnosed. In patients with left-sided HF and resting mean PA pressure ≤25 mm Hg during RHC, more frequent PA pressure monitoring using an IHM device can provide additional data for improved diagnosis and patient risk stratification compared with a single RHC alone.
