Mulibrey (Muscle-Liver-Brain-Eye) Nanism syndrome is an extremely rare genetic disorder with multiorgan involvement. Constrictive pericarditis and diastolic dysfunction are the most common causes of mortality. We present a case of a patient with Mulibrey nanism syndrome who underwent pericardiectomy at 12 years old and was able to live 44 years more with relatively stable and asymptomatic diastolic congestive heart failure (CHF). This case highlights the importance of early recognition and treatment of constrictive pericarditis in these patients.
