Intracardiac echocardiography imaging directly from the left heart chambers via transseptal access provides comprehensive assessment to guide complex left-sided electrophysiology procedures.
Left-sided intracardiac echocardiography via transseptal access offers enhanced visualization for guiding complex electrophysiology procedures like ablation and LAA occlusion.
Intracardiac echocardiography (ICE) has evolved into an integral imaging modality in contemporary electrophysiology, providing real-time visualization that enhances both the safety and efficacy of complex procedures. While most operators rely exclusively on imaging windows obtained from the right atrium and right ventricle, this may limit comprehensive assessment of left cardiac structures. This review examines the emerging role of ICE imaging directly from the left atrium and left ventricle via transseptal access, with a focus on technical and practical considerations, highlighting catheter positioning, imaging views and relevant anatomical relationships. In addition, we discuss the applications of left atrial/ventricular ICE to guide left-sided electrophysiology procedures, including ablation of atrial and ventricular arrhythmias and left atrial appendage occlusion.
Enriquez et al. (2026) conducted a review in Electrophysiology procedures. Left-sided intracardiac echocardiography (ICE) vs. Right-sided ICE was evaluated. Intracardiac echocardiography imaging directly from the left heart chambers via transseptal access provides comprehensive assessment to guide complex left-sided electrophysiology procedures.
