Catheter ablation of premature ventricular complexes associated with false tendons: A case report

Figure 3 Three-dimensional structure model. A: Left ventricular model established with an intracardiac ultrasound catheter and target map marked by the ST catheter in the left ventricle. In the model, pink represents a false tendon, brown represents the anterior papillary muscle, and green represents the posterior papillary muscle; B: The three-dimensional model during ablation and intracardiac ultrasound indicates that the target point is located at the attachment of the false tendon near the basal side of the interventricular septum.
