Abstract
BACKGROUND
Apical hypertrophic cardiomyopathy (HCM) is considered to have a benign prognosis in terms of cardiovascular mortality. This serial case report aimed to raise awareness of ventricular fibrillation (VF) and sudden cardiac death (SCD) in apical HCM.
CASE SUMMARY
Here we describe two rare cases of apical HCM that presented with documented VF and sudden cardiac collapse. These patients were previously not recommended for primary prevention using implantable cardioverter-defibrillator (ICD) therapy based on current guidelines. However, both received ICD therapy for the secondary prevention of SCD.
CONCLUSION
These cases illustrate serious complications including VF and aborted sudden cardiac arrest in apical HCM patients who are initially not candidates for primary prevention using ICD implantation based on current guidelines.
Core Tip: Apical hypertrophic cardiomyopathy (HCM) is a rare form of non-obstructive HCM. It has a benign prognosis in terms of cardiovascular mortality. Here we describe two rare cases of apical HCM that presented as documented ventricular fibrillation (VF) and sudden cardiac collapse. Although apical HCM has a typically benign prognosis, clinicians must consider that VF can occur and lead to sudden cardiac arrest.
