[Diagnosing complicated congenital heart disease with two-dimensional echocardiography and three-segment concept]
Insights
The three-segment heart anatomy concept simplifies diagnosing complicated congenital heart disease (CHD) using two-dimensional echocardiography (2DE). This systematic approach enhances diagnostic accuracy for surgical planning.
Area of Science:
- Cardiology
- Medical Imaging
- Pediatric Medicine
Background:
- Congenital heart disease (CHD) presents complex diagnostic challenges.
- Accurate anatomical assessment is crucial for effective CHD management.
- Two-dimensional echocardiography (2DE) is a primary imaging modality for CHD.
Purpose of the Study:
- To evaluate the utility of a three-segment heart anatomy concept in diagnosing complicated CHD.
- To assess the diagnostic accuracy of 2DE when applying this conceptual framework.
Main Methods:
- A retrospective analysis of 920 cases diagnosed with CHD using 2DE and the three-segment heart anatomy concept.
- Comparison of 2DE findings with angiocardiography (822 cases) and surgical confirmation (584 cases).
Main Results:
- The three-segment concept categorized atrial position, atrioventricular valves, ventricle position, and great artery relations.
- 2DE diagnosed 823 cases with an overall accuracy rate of 89.5%.
- Specific findings included situs solitus (855), situs inversus (53), situs ambiguus (12), and various great artery anomalies.
Conclusions:
- The three-segment heart anatomy concept provides a simple, systematic method for diagnosing complicated CHD via 2DE.
- Segment-by-segment analysis using this concept offers a clear basis for surgical interventions.
Objective:
To apply three-segment heart anatomy concept to two-dimensional echocardiography (2DE) in the diagnosis of complicated congenital heart disease (CHD).
Methods:
920 cases of CHD were diagnosed with 2DE and three-segment heart anatomy concept. 822 out of the 920 cases underwent angiocardiography, and 584 cases were confirmed by operation.
Results:
According to three-segment heart anatomy concept of atrial position, 855 cases were situs solitus (including 89 cases of left superior vena cava and 31 cases of complete anomalous pulmonary venous drainage), 53 cases were situs inversus, and 12 cases were situs ambigus. As to atrial-ventricular valve, 747 cases were both opening, 112 cases had one-side atresia, and 61 cases had one together valve; As to ventricle position, 606 cases were dextro-loop, 111 cases had levo-loop, and 203 cases had single ventricle (including 24 cases), As to cor biloculare of great artery relation, 304 cases had normal relation of great arteries, including 35 cases of pulmonary atresia, 219 cases had right-transposition of great arteries, 240 cases had left-transposition of great arteries, 32 cases were mirror to normal, and 25 cases had persistent truncus arteriosus. 823 cases were diagnosed with 2DE, with a total accurate rate of 89.5%.
Conclusion:
Applying three-segment heart anatomy concept to 2DE to diagnose complicated CHD and analyzing the heart segment by segment will make the diagnosis simple and systematic, providing a concise basis for heart surgeries.
