Key result
CMR accurately characterizes ventricular morphology and myocardial tissue to confirm relative apical hypertrophic cardiomyopathy.
Case Report (n=1)
No
This case highlights the utility of CMR in accurately diagnosing apical hypertrophic cardiomyopathy and characterizing microvascular dysfunction when echocardiography is limited.
CMR may aid diagnosis of relative apical HCM in select cases; leaves open need for prospective validation before wider adoption.
A 72-year-old female presents with breathlessness. ECG demonstrated deep T-wave inversion in the praecordial leads. Echocardiogram was limited but demonstrated no obvious impairment in left ventricular systolic function or significant valve dysfunction. CMR was conclusive for a diagnosis of apical hypertrophic cardiomyopathy with additional microvascular dysfunction in the thickened and dysfunctional apical segments. This case highlights the uniquely powerful nature of CMR in its ability to accurately visualise and quantify ventricular morphology, with the additional strengths to characterise myocardial tissue and the non-invasive assessment of microvascular dysfunction.

Shergill et al. (2023) conducted a case report in Apical hypertrophic cardiomyopathy (n=1). Cardiac magnetic resonance (CMR) was evaluated on Diagnosis of apical hypertrophic cardiomyopathy and microvascular dysfunction. Cardiac magnetic resonance imaging accurately visualized ventricular morphology and characterized myocardial tissue, confirming a diagnosis of relative apical hypertrophic cardiomyopathy.
