New ICE technologies help better guide structural heart and electrophysiology procedures
uses catheter-based array to image anatomy and devices inside the heart to help guide procedures. ICE is primarily used in ablation procedures and .
Both transthoracic (TTE) and are used for guiding transcatheter interventions, but they have limitations. ICE provides the advantage of imaging from within the heart, providing shorter image distances and higher resolution. ICE may be performed without sedation and avoids esophageal intubation as with TEE. But, limitations of ICE include the need for additional venous access with possibility of vascular complications, potentially higher costs and a learning curve for new operators.[1]
ICE can be helpful in guiding transseptal punctures for both EP lab and structural heart device transseptal punctures (including ), transcatheter aortic valve replacement (TAVR), transcatheter mitral valve repair (TMVR), and transcatheter closure of paravalvular leak (PVL), patent ductus arteriosus (PDA), atrial septal defects (ASD), ventricular septal defect (VSD), and patent foramen ovale (PFO).[2]
ICE has been widely adopted in the EP lab to guide transseptal punctures due to its ability to define atrial septal anatomy and provide visualization of transseptal catheter position in relation to other structures within the heart.[3]
