The septal arteries in the differential diagnosis of constrictive pericarditis
Insights
Septal artery motion during angiography can differentiate constrictive pericarditis from restrictive cardiomyopathy. This angiographic sign helps distinguish these conditions in patients with diastolic filling restrictions.
Area of Science:
- Cardiology
- Diagnostic Imaging
Background:
- Ventricular diastolic filling restriction can stem from constrictive pericarditis or restrictive cardiomyopathy.
- Differentiating these conditions is crucial for appropriate patient management.
Purpose of the Study:
- To evaluate the utility of coronary angiographic motion patterns in distinguishing constrictive pericarditis from restrictive cardiomyopathy.
Main Methods:
- An angiographic study assessed septal and left marginal artery motion.
- Patients with constrictive pericarditis (n=12), restrictive cardiomyopathy (n=10), and normal coronary angiograms (n=21) were included.
Main Results:
- Septal artery displacement was significantly exaggerated in constrictive pericarditis (23 +/- 2.04 mm) compared to restrictive cardiomyopathy (9 +/- 0.81 mm) and normals.
- The "corrugating index" of left marginal arteries showed no significant difference between groups.
Conclusions:
- Abnormal septal artery displacement on angiography is a valuable indicator for differentiating constrictive pericarditis from restrictive cardiomyopathy.
Abstract:
Angiographic study of the motion of the septal and left marginal arteries was performed in patients with restriction in ventricular diastolic filling in order to separate patients with constrictive pericarditis from those with restrictive cardiomyopathy. Twelve patients with constrictive pericarditis (group I) and 10 patients with restrictive cardiomyopathy (group II) were evaluated and compared with 21 patients with normal coronary angiograms (group III). The displacement of the septal arteries (23 +/- 2.04 mm) was abnormally exaggerated in group I and normal (9 +/- 0.81 mm) in groups II and III. The displacement of the left marginal arteries as seen by the "corrugating index" was similar in all groups. We conclude that study of the displacement of the septal arteries is a useful angiographic sign that helps to separate constrictive pericarditis from restrictive cardiomyopathy and normals.
