Overview
Transthoracic echocardiography (TTE) is used in atrial flutter to evaluate the sizes of left and right atria. Transesophageal echocardiography (TEE) is used to evaluate the presence of thrombus and selection of candidates for cardioversion.
Echocardiography
TTE is the preferred modality for evaluating the sizes of right and left atria in atrial flutter. It can also be used to assist in the diagnosis of valvular heart disease, left ventricular hypertrophy, heart failure and pericardial disease. Consistent echocardiographic findings in atrial flutter include regular undulatory waves of the posterior left atrial wall and upper left interventricular septum coinciding with each flutter wave of the electrocardiogram[1].
TEE is preferred over TTE, which has a low sensitivity, for detecting left atrial thrombus which is unusual in stable atrial flutter.
