A case of left atrial thrombus detected by intra-left atrial echocardiography

Figures

• 

  Figure 1. Transesophageal echocardiography performed 9 days before catheter ablation for atrial fibrillation. Spontaneous echocardiographic contrast was documented. LA = left atrium.

• 

  Figure 2. Intracardiac echocardiography from the left atrial (LA) cavity demonstrated that the hyperechoic and flat mass lesion adhered to the posterior wall (arrows). Transverse views at high (A), middle (B), and low levels (C) of the LA posterior wall are shown. LA posterior views of CARTO (Biosense Webster, Diamond Bar, CA) image are provided in the right. Brown color indicates thrombus and pink color indicates esophagus.

• 

  Figure 3. Transesophageal echocardiography done just after termination of the procedure. The posterior wall thrombus was documented in the views not directed by guideline (arrows).
