During intraoperative transesophageal echocardiography (TEE) examination, the LA contractility was demonstrated with distinct mitral inflow E and A waves, and atrial systolic reversal waves of pulmonary venous inflow [Figure 1]. Simultaneous interrogation of the LAA with pulse wave Doppler (PWD) demonstrated characteristic dyssynchronous contraction and relaxation waves suggesting a non-SR [Figure 2 and Video 1].
