Left bundle area pacing: Guiding implant depth by ring measurements.

Background: Criteria for successful left bundle area pacing (LBAP) are in flux and currently guided by lead tip measurements. Lead ring measurements during LBAP have not been well studied.

Objective: The purpose of this study was to investigate dynamics in pacing parameters during successful and unsuccessful lead implant attempts.

First experience of 3D rotational angiography fusion with NavX electroanatomical mapping to guide catheter ablation of atrial fibrillation.

Background: Rotational angiography of the left atrium with 3-dimensional reconstruction (3DATG) is a new imaging tool to guide atrial fibrillation (AF) ablation. Its role as part of a complex imaging strategy with NavX has not yet been evaluated.

Objective: To determine the feasibility of using 3DATG fusion with NavX in guiding AF ablation.

First experience with rotational angiography of the right ventricle to guide ventricular tachycardia ablation.

Background: Rotational angiography with three-dimensional reconstruction (3DRA) is a new imaging tool recently introduced to guide mapping and ablation of the left atrium.

Objective: The purpose of this study was to determine the utility of 3DRA for imaging the ventricles and guiding ventricular tachycardia (VT) ablation.

Methods: Using the Philips Allura Xper FD10 system, 3DRA was performed in eight patients referred for right ventricular outflow tract (RVOT) VT ablation.
