Key result
Comprehensive evaluation with ICD interrogation helps diagnose and treat persistent post-myectomy symptoms in HCM.
Case Report (n=1)
In patients with hypertrophic cardiomyopathy who remain symptomatic after surgical myectomy, a comprehensive evaluation including device interrogation is essential to identify alternative etiologies.
May identify occult causes of persistent symptoms post-myectomy in HCM via ICD interrogation; leaves open prospective validation before broader adoption.
We describe the case of a young female patient with hypertrophic cardiomyopathy (HCM) with a dual chamber implantable cardioverter defibrillator (ICD), and complete heart block from a prior septal ablation procedure. Due to persistent left ventricular outflow tract (LVOT) obstruction and symptoms, she underwent surgical myectomy. Her exertional symptoms continued despite improved LVOT flow parameters. A comprehensive evaluation, including ICD interrogation, helped arrive at the correct diagnosis and treatment plan.

Goel et al. (2022) conducted a case report in Hypertrophic cardiomyopathy (HCM) (n=1). Surgical myectomy and ICD interrogation was evaluated. Comprehensive evaluation including ICD interrogation helped diagnose and treat persistent exertional symptoms in a young female with HCM following surgical myectomy.
