Assess the utility of multimodal cardiac imaging and Doppler-based tissue characterization in identifying apical hypertrophic cardiomyopathy.
Evaluated a 60-year-old male with hypertension, left ventricular hypertrophy, and chest pain using electrocardiography and contrast stress echocardiography.
Performed confirmatory cardiac magnetic resonance (CMR), single-photon emission computed tomography (SPECT), and velocity vector imaging (VVI) to assess myocardial tissue strain.
Contrast echocardiography and CMR confirmed apical hypertrophic cardiomyopathy, demonstrating an apical filling defect and a characteristic 'ace of spades' left ventricular cavity.
Velocity vector imaging identified lower than normal maximal longitudinal tissue velocities and negative apical longitudinal strain without a base-to-apex gradient, despite normal strain in basal and mid-myocardial segments.

Structured PICO

Population

1 60-year-old male with previous hypertension, left ventricle hypertrophy, and coronary artery disease presenting with exertional chest pain

Intervention

Multimodality imaging including contrast echocardiography, cardiac magnetic resonance, single photon emission computed tomography (SPECT), and velocity vector imaging

Outcome

Diagnosis of apical hypertrophic cardiomyopathysurrogate

Intravenous contrast enhancement and newer Doppler-based techniques allowing tissue characterization can improve the diagnostic accuracy of apical hypertrophic cardiomyopathy, a condition occasionally missed by conventional echocardiography.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

May aid apical HCM diagnosis in select cases; hypothesis-generating and requires prospective validation.
