The Growing Role of Intracardiac Echo in Congenital Heart Disease Interventions

Area of Science:

• Cardiology
• Medical Imaging
• Interventional Cardiology

Background:

• Improved survival in congenital heart disease (CHD) has led to a growing population of adults with CHD (ACHDs).
• ACHDs often require ongoing transcatheter interventions for residual defects, valve dysfunction, and arrhythmias.
• Effective imaging is crucial for the success and safety of these complex interventions.

Purpose of the Study:

• To review the expanding role of Intracardiac Echocardiography (ICE) in adult congenital heart disease (ACHD) interventions.
• To highlight the advantages of ICE over other imaging modalities in ACHD procedures.
• To discuss ICE applications in both structural and electrophysiological interventions for ACHDs.

Main Methods:

• Review of current literature and technological advancements in ICE.
• Comparison of ICE with transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) in ACHD settings.
• Analysis of ICE's utility in guiding transcatheter structural and electrophysiological procedures.

Main Results:

• ICE offers superior visualization and real-time guidance compared to TEE and TTE.
• ICE facilitates procedures without the need for general anesthesia in many cases.
• Technological advancements are expanding the capabilities and applications of ICE in ACHD interventions.

Conclusions:

• Intracardiac echocardiography is becoming the preferred imaging modality for many ACHD transcatheter interventions.
• ICE enhances procedural precision, reduces complications, and improves outcomes for ACHD patients.
• The integration of ICE is transforming the long-term management and care of the growing ACHD population.
