1Department of Medicine, University of California, Los Angeles School of Medicine.
Insights
Adults with congenital heart disease require specialized care. Comprehensive echocardiography and Doppler assessments are crucial for diagnosing and managing complex cardiac conditions in these patients.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Advances in diagnosis and management enable congenital heart disease patients to reach adulthood.
- Lifelong care necessitates understanding original defects, temporal changes, and adult disease/surgical impacts.
Purpose of the Study:
- To review the role of echocardiography and Doppler assessment in managing adult congenital heart disease.
- To detail the comprehensive evaluation of anatomical and hemodynamic abnormalities.
Main Methods:
- Utilizing combined two-dimensional and color-flow echocardiography for anatomical delineation.
- Employing pulsed and continuous-wave Doppler for hemodynamic assessment.
- Evaluating chamber sizes, myocardial function, and detecting various lesions and obstructions.
Main Results:
- Echocardiography and Doppler have revolutionized the management of adult congenital heart disease.
- Detailed assessment identifies shunts, obstructive/regurgitant lesions, malpositions, and conduit/venous obstructions.
- Quantification of stenosis and regurgitation is essential for patient care.
Conclusions:
- A complete echo-Doppler examination is vital for all adult congenital heart disease patients, whether operated or unoperated.
- This comprehensive approach ensures accurate diagnosis and guides appropriate management strategies.
- Understanding intracardiac hemodynamics is key to optimizing outcomes.
Abstract:
Enormous strides in diagnosis and management have allowed many patients with congenital heart disease to reach adulthood. Proper care of these individuals requires knowledge of the anatomic and hemodynamic faults of the original defect, the dynamic changes that occur with time, and the effects of adult diseases or surgical intervention on that physiology. Echocardiographic and Doppler assessment of these patients has revolutionized their management. This article has discussed individual abnormalities such as shunts, obstructive or regurgitant lesions, and great-vessel and chamber malpositions, as well as selective aspects of more complex malformations. In the patient with congenital heart disease, whether unoperated or postoperative, a complete echo-Doppler examination includes complete anatomic delineation of intra- and extracardiac structures using combined two-dimensional and color-flow imaging, assessment of chamber sizes and myocardial function, and complementary pulsed and continuous-wave Doppler and color-flow imaging to search for and quantitate valvular, subvalvular or supravalvular stenosis or regurgitation; extra- and intracardiac conduit stenosis; pulmonary and systemic venous obstruction; transseptal or patch shunts; and intracardiac hemodynamics.
