Abstract
Constrictive pericarditis is a condition of diastolic heart failure with unique hemodynamic manifestations. While potentially curable if treated appropriately, constrictive pericarditis remains a diagnostic challenge, particularly during early manifestation of disease when there are subtle clinical symptoms and when confounding comorbidities are present. In this focused review, we describe the characteristic and diagnostic hemodynamics of constrictive pericarditis as well as the utility of invasive (cardiac catheterization) and noninvasive (echocardiography) diagnostic testing for this complex disease.
