Left Ventricular Torsion by Two-Dimensional Speckle Tracking Echocardiography in Patient with A-Type Amyloid Heart Disease

In this report, we presented a patient with A-type amyloid heart disease who had dynamic left ventricular outflow tract obstruction mimicking hypertrophic obstructive cardiomyopathy. We also investigated left ventricular torsion, untwisting rate and left ventricular longitudinal global strain by two-dimensional speckle tracking echocardiography.
