Key result
Novel CMR parameters like T1 and ECV may improve sudden death risk stratification in HCM.
Why the study?
Hypertrophic cardiomyopathy carries a risk of sudden cardiac death, but risk stratification has remained challenging.
Do novel CMR parameters improve sudden cardiac death risk stratification in patients with hypertrophic cardiomyopathy?
Do novel CMR parameters improve sudden cardiac death risk stratification in patients with hypertrophic cardiomyopathy?
Novel CMR techniques such as T1 mapping and feature tracking show promise in enhancing sudden cardiac death risk stratification in hypertrophic cardiomyopathy.
Hypothesis-generating for SCD risk stratification in HCM; prospective validation required before clinical adoption.
Hypertrophic cardiomyopathy (HCM) is a common genetic disorder with a well described risk of sudden cardiac death; however, risk stratification has remained a challenge. Recently, novel parameters in cardiac magnetic resonance imaging (CMR) have shown promise in helping to improve upon current risk stratification paradigms. In this manuscript, we have reviewed novel CMR risk markers and their utility in HCM. The results of the review showed that T1, extracellular volume, CMR feature tracking, and other miscellaneous novel CMR variables have the potential to improve sudden death risk stratification and may have additional roles in diagnosis and prognosis. The strengths and weaknesses of these imaging techniques, and their potential utility and implementation in HCM risk stratification are discussed.

Alajmi et al. (2024) conducted a review in Hypertrophic cardiomyopathy (HCM). Novel cardiac magnetic resonance imaging (CMR) parameters was evaluated on Sudden death risk stratification, diagnosis, and prognosis. Novel cardiac magnetic resonance imaging parameters, such as T1 and extracellular volume, show potential to improve sudden death risk stratification in hypertrophic cardiomyopathy.
