Video Summary

In this video, several cases were presented that can mimic hypertrophic cardiomyopathy (HCM). The first case involved a 55-year-old active male who experienced chest pain while training. Echo images revealed some thickened walls but no evidence of outflow obstruction or mitral valve abnormalities. The conclusion was that the patient had an athletic heart, which can appear thickened due to ventricular remodeling. The second case involved a 64-year-old male with a history of hypertension and diabetes who presented with syncope. Echo images showed increased wall thickness, but no outflow obstruction or mitral valve abnormalities. The conclusion was that the patient had hypertensive heart disease, which can be difficult to differentiate from HCM. The third case involved a 55-year-old male with a history of carpal tunnel syndrome and chronic kidney disease who presented in cardiogenic shock. Echo images showed thickened walls, peri cardial effusion, and abnormal strain pattern. The conclusion was that the patient had amyloidosis, which can mimic HCM. The fourth case involved a 53-year-old female with palpitations and a pacemaker. Echo images showed hyperdynamic function, increased wall thickness, and abnormal flow through the LVOT. Valsalva maneuver provoked systolic anterior motion of the mitral valve and increased LVOT gradients, indicating obstruction. The conclusion was that the patient had latent HCM, which can be unmasked with provocation. In summary, these cases highlight the importance of recognizing distinguishing characteristics that can help differentiate between HCM and other conditions that mimic it.
