Cardiac MRI Data for Sudden Cardiac Death Survivors, 2009-2019

64 patients, aged 54.9±15.4 years, were admitted between 2009 and 2019 at a tertiary academic institution. The dataset includes demographic, clinical, and laboratory data, along with cardiac magnetic resonance images and reports, collected retrospectively by Paula Chiavenato Marçal. It was used to evaluate the role of CMR in increasing etiological diagnosis for survivors of sudden cardiac death or unstable ventricular arrhythmia.

Use Cases

• Identify cardiac fibrosis patterns based on late gadolinium enhancement findings mentioned in the description
• Assess left ventricular ejection fraction distribution among patients with ventricular arrhythmias
• Determine the most common etiologies of sudden cardiac death in a patient cohort based on CMR results
• Evaluate the diagnostic yield of CMR in patients without a previously identified cardiac cause

Strengths

• 64 patient records with detailed clinical and imaging data
• Data spans a 10-year period from 2009 to 2019
• Includes specific metrics like left ventricular ejection fraction (mean 44±14%) and late gadolinium enhancement prevalence (71.9%)

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data may reflect geographic bias inherent to a single tertiary institution in a developing country
