Key result
A system combining ICE and 3D mapping feasibly reconstructs the left atrium and pulmonary veins without entering the left heart, but is sensitive to distortion during point-by-point mapping.
Integration of intracardiac echocardiography with 3D mapping is feasible for guiding AF ablation without pre-procedural imaging, yielding a 73% success rate at 10 months, though catheter-induced anatomical distortion remains a limitation.
No takes yet. Share an insight, caveat, or question.
May enable right-sided LA mapping; leaves open whether distortion limits ablation accuracy.
Khaykin et al. (2008) studied this question. A system combining ICE and 3D mapping feasibly reconstructs the left atrium and pulmonary veins without entering the left heart, but is sensitive to distortion during point-by-point mapping.
