Integration of Structures Defined on Intracardiac Echocardiography Into Electroanatomic Maps

(A) A bipolar voltage map in RAO and LAO projections using cut-offs of 0.5 to 1.5 mV. There is extensive low voltage in the right ventricular outflow tract without any clear definition of where the surgical patches sit. (B to D) Intracardiac echocardiography (ICE) is used to collect anatomy of the ventricular septal defect patch (VSDP) (brown) and the right ventricular outflow tract patch (RVOTP) (green). (E, F) The anatomy of surgical patches can be superimposed on the voltage map of the ventricle using the CartoSound module. This can then be used to plan ablation of 1 or more anatomical isthmuses. AP = anteroposterior; LAO = left anterior oblique; PA = posteroanterior; RAO = right anterior oblique.
