Echocardiographic diagnosis of pericardial disease
Insights
Echocardiography reveals distinct patterns in constrictive pericarditis, differentiating between chronic fibrosis, effusive-constrictive pericarditis, and subacute dry pericarditis based on echo characteristics.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Constrictive pericarditis is a serious cardiac condition.
- Accurate diagnosis is crucial for effective treatment.
Purpose of the Study:
- To correlate echocardiographic findings with specific pericardial pathologies.
- To identify distinct echocardiographic patterns for different types of pericardial disease.
Main Methods:
- Echocardiograms were performed on 11 patients with confirmed constrictive or effusive-constrictive pericarditis.
- Cardiac catheterization and pericardiectomy were used for confirmation.
- Echocardiographic patterns were analyzed and categorized.
Main Results:
- Three distinct echocardiographic patterns were identified.
- Pattern 1: Parallel echoes in chronic fibrosed pericardium.
- Pattern 2: Echo-free space in effusive-constrictive pericarditis.
- Pattern 3: Numerous signals in subacute dry pericarditis.
Conclusions:
- Echocardiography can differentiate between types of pericardial disease.
- Specific echo patterns correlate with distinct pericardial pathologies.
- This aids in diagnosing and managing constrictive pericarditis.
Abstract:
Echocardiograms were performed in 11 patients with constrictive pericarditis or effusive-constrictive pericarditis confirmed by cardiac catheterization and pericardiectomy. Three echocardiographic patterns of pericardial disease were noted and were related to three types of pericardial pathology. Parallel moving echoes separated by a clear space were reflected from chronically fibrosed and thickened pericardium without associated pericardial exudate. Effusive-constrictive pericarditis or subacute wet pericarditis was characterized on the echocardiogram by a posterior echo-free space representing the liquid pericardial effusion and multiple ultrasonic lines from the thickened visceral pericardium. Subacute dry pericarditis was associated with numerous ultrasonic signals filling the space between the visceral pericardium and the relatively flat parietal pericardium. These ultrasonic signals were reflected from coagulated pericardial exudate which was adherent both to the parietal pericardium and the visceral pericardium. Parallel moving echoes or dense bands of echoes were reflected from either or both thickened visceral and parietal pericardium.
