Article Synopsis
- Left ventricular apical aneurysm is linked to serious heart arrhythmias in patients with hypertrophic cardiomyopathy (HCM), yet different guidelines classify its risk level differently, with the 2020 AHA/ACC guidelines recognizing it as a major risk factor.
- A study with 99 Japanese HCM patients found that those with apical aneurysms, high pressure gradients, or late gadolinium enhancement were more likely to receive appropriate interventions from their implantable cardioverter-defibrillators (ICDs) over an average of 6.2 years.
- Specifically, the presence of an apical aneurysm significantly increased the annual rate of ICD interventions, indicating the need for careful consideration of these imaging characteristics when deciding
The European Society of Cardiology (ESC) clinical risk model is reported in predicting sudden death of hypertrophic cardiomyopathy (HCM). We examined the validity of this model and investigated the significance of ejection fraction (EF) in predicting the prognosis using ESC risk model in HCM patients. 305 HCM patients (198 males) were followed (median follow-up 4.

Methods and results: A total of 237 HCM patients (median age, 62 years; 143 male) underwent T2-weighted, cine and late gadolinium enhancement (LGE) imaging, and were followed (median duration, 3.4 years) for life-threatening arrhythmic events.
Implantable cardioverter-defibrillator (ICD) is effective to prevent sudden death in HCM patients. We reviewed ICD records to analyze the relation between life-threatening arrhythmia and late gadolinium enhancement (LGE) on cardiovascular magnetic resonance (CMR) in Japanese hypertrophic cardiomyopathy (HCM) patients. In 102 consecutive patients (median age 63 years, 63 males) implanted with an ICD after CMR with gadolinium enhancement (median follow-up 2.
View Article and Find Full Text PDFBackground: In addition to the presence of late gadolinium enhancement (LGE) on cardiovascular magnetic resonance (CMR), the extent of LGE is considered clinically important in hypertrophic cardiomyopathy (HCM). We evaluated the extent of LGE on CMR in a large series of Japanese HCM patients.
Methods and results: CMR was performed in 317 HCM patients (147 male).
