IgG4-Related Pericarditis

Key Points

IgG4-related pericarditis is a significant cause of constrictive physiology, warranting immediate attention.
Multimodality imaging and pericardial biopsy are essential diagnostic tools to confirm the condition and guide treatment.
Treatment includes surgical pericardiectomy, often resulting in curative outcomes for affected individuals.
Lifelong follow-up is necessary to ensure effective management of any systemic disease associated with IgG4-related conditions.

Abstract

IgG4-RD pericarditis is a rare but important cause of constrictive physiology. Multimodality imaging and pericardial biopsy are critical for diagnosis. Surgical pericardiectomy is often curative, but lifelong follow-up is necessary to monitor systemic disease.
