Figure 2.

Mapping of the LV summit PVC using the left atrial appendage. A and B show the fluoroscopy projections with the catheter placed inside the appendage resting over the epicardial LV. The relationship of the appendage and the coronary arteries is shown in the LAO and RAO projection. (C) shows the ICE image with the catheter at the tip of the left atrial appendage. The ICE probe is positioned inside the RVOT and tilted up to visualize the left atrial appendage. (D) Electro‐anatomical map showing the left atrial appendage and the RVOT relationship. (E) The PVC signal recorded through the appendage. (F) Carto‐Sound reconstruction of the anatomy showing the intimate relation of the RVOT, LVOT, and left atrial appendage.
