[Right heart catheterization : Technique, interpretation, and indications].

Despite the widespread use of non-invasive imaging modalities, right heart catheterization remains the gold standard for the hemodynamic assessment of various cardiopulmonary disorders. A Swan-Ganz catheter allows the direct measurement of venous, intracardiac, and pulmonary arterial pressures, as well as cardiac output. Its execution and interpretation require technical precision, given the numerous potential sources of error. This review provides an overview of best practices, common pitfalls, and current clinical indications for right heart catheterization.
