Key result
Ultrasound and MRI guide diagnosis and risk stratification of ventricular arrhythmias in ischemic cardiomyopathy.
Why the study?
Most life-threatening ventricular arrhythmias are associated with ischemic cardiomyopathy, and advances in imaging may help clinicians identify high-risk patients early to optimize risk stratification, treatment, and outcomes.
Echocardiography and CMR are essential tools for identifying proarrhythmic substrates, guiding ablation therapy, and predicting sudden cardiac death risk in patients with ischemic cardiomyopathy.
May aid arrhythmia risk stratification in ischemic cardiomyopathy; leaves open prospective validation before guiding therapy.
Ventricular arrhythmia (VA) is one of the common complications of many heart diseases in clinical practice, even some of its clinical symptoms are mild and non-specific, but the other may lead to sudden cardiac death (SCD) and most life-threatening VA is associated with ischemic cardiomyopathy (ICM). Nowadays, the developments in imaging techniques have provided clues to identify these highly variable VAs, which make clinicians identify patients with VA early and effectively who may have fatal consequences. Thereafter, it is beneficial to manage the risk stratification of patients, optimize their follow-up treatment, and improve clinical outcomes. This article reviews current ultrasound and magnetic resonance imaging techniques that can aid in diagnosis, treatment and prognosis, and provides clinicians with practical imaging and analytical recommendations to further identify patients with ICM who may develop VA.

Hu et al. (2025) conducted a review in Ventricular arrhythmia in ischemic cardiomyopathy. Ultrasound and magnetic resonance imaging was evaluated. Ultrasound and magnetic resonance imaging techniques provide valuable tools for the diagnosis, risk stratification, and prognostic assessment of ventricular arrhythmias in ischemic cardiomyopathy.
