Actual (reported)The purpose of this study is to use cardiac magnetic resonance imaging (CMR) and echocardiographic tissue Doppler imaging to demonstrate a unique restrictive cardiomyopathy of sickle cell disease. The investigators will characterize its frequency and how it might change (e.g., presence/absence and severity) over a 2-year period.

Actual (reported)Frequency of the Diffuse Myocardial Fibrosis Phenotype
The occurrence of an abnormally increased extracellular volume (ECV) measurement \[i.e., the presence of the diffuse myocardial fibrosis phenotype\] as assessed by cardiac magnetic resonance imaging (CMR) using T1 mapping before and after administration of gadolinium. Expressed as number of participants with the diffuse myocardial fibrosis phenotype in each stratum.
Assessed annually over a 2-year period (3 assessments over 2 years)
Stability of the Diffuse Myocardial Fibrosis Phenotype Over Time
Assessed annually over a 2-year period (3 assessments over 2 years)
* Age 6 to 13.99 years * Cardiac magnetic resonance imaging (CMR)
* Age 14 to 20.99 years * Detectible and quantifiable TRJV with reported value * Cardiac magnetic resonance imaging (CMR)
* Age ≥21 years * Detectible and quantifiable TRJV with reported value * Cardiac magnetic resonance imaging (CMR)
* Age ≥6 years. * Current use of disease-modifying therapy \[hydroxyurea, chronic transfusions, or both (given concurrently, sequentially, or both)\] that was initiated at \<3 years of age, and for which there has been no interruption of therapy for \>6 consecutive months since the initiation of disease-modifying therapy. * Cardiac magnetic resonance imaging (CMR)
CMR is obtained on all participants in all arms/groups
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
Enrolling a maximum of 40 participants in the entire study across four age strata: A, 6 - 13.9 years; B, 14 - 20.9 years; C, 21 years and older; and D, 6 years and older.

Blood, DNA, and urine specimens.
All participants in strata A, B and C had severe diffuse myocardial fibrosis. That is, all participants had the phenotype for which we assessed, so correlative studies (e.g., affected vs. non-affected) could not be performed. Therefore, we amended the protocol and opened an additional, fourth stratum (D) to study individuals who were previously not eligible for inclusion.
