Insights
Single-ventricle heart defects require blood flow redirection. Many adults face long-term issues like heart failure and arrhythmias, impacting quality of life.
Area of Science:
- Cardiology
- Pediatric Cardiac Surgery
- Congenital Heart Disease
Context:
- Single-ventricle physiology presents unique challenges in managing systemic and pulmonary blood flow.
- Surgical palliation aims to reroute venous return directly to the pulmonary artery, bypassing the underdeveloped right ventricle.
- Increasing survival rates mean more adults live with complex single-ventricle physiology.
Purpose:
- To describe the long-term outcomes and complications associated with the surgical palliation of single-ventricle heart defects.
- To highlight the prevalence and nature of late sequelae in adult survivors.
- To underscore the ongoing need for specialized adult congenital cardiology care.
Summary:
- Treatment involves redirecting systemic venous blood to the pulmonary artery without right heart involvement.
- A significant proportion of adults with single-ventricle defects experience late complications.
- Common issues include heart failure, arrhythmias, cyanosis, thromboembolic events, and neurological deficits.
Impact:
- Improved understanding of long-term morbidity in single-ventricle survivors.
- Highlights the critical need for lifelong monitoring and management of these complex patients.
- Informs strategies for enhancing quality of life and addressing specific complications in adult congenital heart disease.
Abstract:
Treatment of a single-ventricle heart defect involves redirecting of systemic venous blood returning to the heart to gradually flow directly into the pulmonary artery without the functional right side of the heart being involved. In developed countries, three out of four persons with this ailment will nowadays reach adulthood. Among these, at least one out of four presents significant associated problems and late complications. The most significant problems include heart failure, arrhythmias, cyanosis and thromboembolic complications that increase over time. In addition to these, neurological complications have an influence on the quality of life in some patients.
