Insights
Adults with single ventricle physiology after Fontan palliation require specialized echocardiography. This review offers a practical guide for evaluating these complex adult Fontan patients.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Echocardiography
Background:
- Improved survival in single ventricle physiology patients post-Fontan palliation leads to a growing adult population.
- Management of adult Fontan patients presents significant clinical challenges in contemporary cardiology.
- Complex anatomical and physiological abnormalities necessitate detailed echocardiographic evaluation.
Purpose of the Study:
- To provide a practical, clinically oriented approach to echocardiographic evaluation.
- To guide clinicians in assessing adult patients with single ventricle physiology post-Fontan.
- To aid in routine follow-up and pre-intervention evaluations.
Main Methods:
- Review of current echocardiographic techniques for single ventricle physiology.
- Integration of anatomical knowledge and potential long-term complications.
- Clinical case examples and interpretation strategies.
Main Results:
- Echocardiography is crucial for evaluating adult Fontan patients.
- Understanding basic lesions and complications improves interpretation.
- A structured approach enhances diagnostic accuracy.
Conclusions:
- Echocardiographic assessment is vital for adult Fontan survivors.
- This review provides a practical framework for echocardiographers.
- Improved understanding facilitates better patient management and outcomes.
Abstract:
Recent advances in surgical techniques and perioperative care for patients with single ventricle physiology have led to a remarkable improvement in long-term survival, such that now the majority of patients with single ventricle physiology are living to adulthood after Fontan palliation. The management of adult patients with Fontan physiology is one of the most challenging clinical dilemmas encountered in contemporary cardiology. The complex and heterogeneous anatomical and physiological abnormalities seen in Fontan patients mandate that any clinical evaluation, either for routine follow-up or preoperative evaluation prior to any transcatheter or surgical intervention, incorporates detailed information from a careful and thorough echocardiographic examination, These examinations, however, can be complex and confusing, even for experienced echocardiographers. Ideally, the interpretation of these studies is informed by an understanding of the basic anatomical lesions and of the potential long-term complications encountered in adult single ventricle patients. In this review, we present a practical and clinically oriented approach to the echocardiographic evaluation of adult patients with single ventricle physiology post-Fontan.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
