a–d Typical ablation planes with CTI on the left side. The ablation catheter is dragged from the tricuspid valve ring to the inferior caval vein, maintaining the catheter on the echocardiographic plane to achieve the best possible line; e insufficient contact of the ablation catheter tip (blue arrow) to the target tissue due to a prominent Eustachian ridge; f corrected tissue contact by inversion of the ablation catheter (blue arrow)
