A 69-year-old male with apical hypertrophic cardiomyopathy and an apical aneurysm exhibited a characteristic biphasic lobster-claw Doppler pattern indicating mid-ventricular systolic obstruction.
Case Report (n=1)
No
The lobster-claw Doppler pattern is a useful hemodynamic sign for identifying mid-cavity systolic obstruction in patients with apical hypertrophic cardiomyopathy and apical aneurysm.
Żarek-Starzewska et al. (Mon,) conducted a case report in Apical hypertrophic cardiomyopathy with apical aneurysm (n=1). Transthoracic echocardiography and cardiac magnetic resonance imaging was evaluated. A 69-year-old male with apical hypertrophic cardiomyopathy and an apical aneurysm exhibited a characteristic biphasic lobster-claw Doppler pattern indicating mid-ventricular systolic obstruction.
