Key result
Pediatric idiopathic restrictive cardiomyopathy carries a poor prognosis with ~1 year median survival.
Why the study?
Restrictive cardiomyopathy is the least common cardiomyopathy type and presents a diagnostic challenge due to varied pathogenesis, clinical presentation, and evaluation.
This review provides a comprehensive overview of the etiologies, diagnostic evaluation, and management strategies for various types of restrictive cardiomyopathies.
Restrictive cardiomyopathy (RCM) includes a heterogeneous group of diseases that cause increased myocardial stiffness, leading to impaired ventricular relaxation and severe diastolic dysfunction. Given that it is the least common type of cardiomyopathy, it can be a diagnostic challenge due to its varied pathogenesis, clinical presentation, and diagnostic evaluation. In this review, we provide an overview of different etiologies of RCM and examine the diagnostic and treatment approaches for various types.

Gowda et al. (2022) conducted a review in restrictive cardiomyopathy. The prognosis in children with idiopathic restrictive cardiomyopathy is poor, with a median survival of 1 to 1.4 years.
