Implication
Necessitates RHC for accurate PH diagnosis; leaves open development of reliable noninvasive alternatives in prospective research.

Population
Pulmonary hypertension
Limitations
- Insufficient evidence to add an exercise criterion to the definition of pulmonary hypertension.
- Right heart catheterization requires further standardization, including uniformity of the pressure transducer zero level.
- Volume or exercise challenge during catheterization requires further evaluation before general practice recommendation.
- Early diagnosis of PAH remains difficult.

Hoeper et al. (2013) conducted a review in Pulmonary hypertension. Right heart catheterization remains essential for diagnosing pulmonary hypertension, which is hemodynamically defined by a mean pulmonary artery pressure ≥ 25 mm Hg at rest.
