Right-heart catheterization remains essential for PAH diagnosis over echocardiography; reinforces gold-standard status while leaving noninvasive alternatives open for validation.
This review highlights the critical role of right-heart catheterization as the gold standard for diagnosing and evaluating pulmonary arterial hypertension, as echocardiography alone is insufficient.
Oudiz et al. (2005) conducted a review in Pulmonary Arterial Hypertension. Cardiac catheterization was evaluated. Cardiac catheterization remains the gold standard for diagnosing pulmonary arterial hypertension, defined hemodynamically as a mean pulmonary arterial pressure of ≥25 mm Hg.
