Two-dimensional echocardiography in discrete subaortic stenosis.
The American Journal of Cardiology
|March 15, 1984
Summary
Two-dimensional echocardiography (2-D echo) accurately identifies discrete subaortic stenosis (DSS) presence and type. However, 2-D echo cannot reliably assess the obstruction severity in patients with DSS.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Discrete subaortic stenosis (DSS) is a congenital heart defect.
- Accurate diagnosis is crucial for patient management.
Purpose of the Study:
- To evaluate the diagnostic accuracy of 2-dimensional echocardiography (2-D echo) for discrete subaortic stenosis (DSS).
- To compare 2-D echo findings with cardiac catheterization and surgical outcomes.
Main Methods:
- Thirty-seven patients with DSS underwent 2-D echo and cardiac catheterization.
- Echocardiographic diagnoses were confirmed during subsequent cardiac surgery.
Main Results:
- 2-D echo correctly identified the presence and type of DSS in 35 out of 37 patients.
- Angiography confirmed 2-D echo findings in most cases, with surgery validating discrepancies.
- 2-D echo was unable to reliably assess the severity of obstruction.
Conclusions:
- 2-D echo is a reliable tool for diagnosing the presence and type of discrete subaortic stenosis.
- Assessment of obstruction severity by 2-D echo requires further investigation.
