Comparison of Contractility Patterns on Left Ventriculogram Versus Longitudinal Strain by Echocardiography in Patients With Takotsubo Cardiomyopathy
Abstract
Background
Takotsubo cardiomyopathy (TTC) is characterized by transient left ventricular (LV) dysfunction, electrocardiographic changes that can mimic acute myocardial infarction (MI), and release of myocardial enzymes in the absence of obstructive coronary artery disease (CAD). Conventionally, gross visual assessment of LV angiogram has been used to classify TTC. We aim to compare quantitative assessment of different regions of LV on angiogram and segmental strain on transthoracic echo to determine a better way to classify TTC rather than conventional qualitative visual assessment.
