Warren Jackman's Art of War: A Sniper's Approach to Catheter Ablation-Figure Chapter 11

Figure Chapter 11

Pdf Summary

The document contains a series of figures related to ventricular tachycardia (VT) mapping and ablation. The figures depict various mapping techniques and potential exit points of VT. The document suggests using echo, ventriculogram, or MRI to identify the location of scar tissue. It emphasizes the importance of predicting the exit point of each VT and using substrate mapping to identify the extent of scar tissue. Abnormal potentials and late potentials in sinus rhythm should be tagged and pace mapping can be performed to identify potential exit points. If VT is induced, entrainment mapping can be used to guide ablation. If VT remains inducible, repeat mapping techniques can be employed. Figures also show different types of VT and their QRS complexes. The document includes information about pacing protocols, ablation endpoints, and post-ablation results. It also covers topics such as concealed fusion, manifest fusion, and central and proximal exit points. The figures demonstrate the use of different mapping catheter positions and pacing sites. The document highlights the need to ablate abnormal potentials and scar tissue and shares pre- and post-ablation EGM-QRS values. Other topics covered include Purkinje fibers, pre-excitation syndromes, and different types of bundle branch block.
