The angiographic appearance of the coronary arteries in constrictive pericarditis
Insights
Lack of coronary artery motion is a key indicator of constrictive pericarditis (CP), differentiating it from other heart conditions. This finding aids diagnosis when typical methods are unavailable or hemodynamics are unusual.
Area of Science:
- Cardiology
- Diagnostic Imaging
- Cardiac Physiology
Background:
- Constrictive pericarditis (CP) presents diagnostic challenges, often mimicking other cardiac conditions.
- Evaluating coronary artery motion can provide unique insights into cardiac health.
Purpose of the Study:
- To investigate coronary artery motion patterns in patients with constrictive pericarditis and compare them to other cardiac diseases.
- To determine if absent coronary artery motion is a specific indicator for constrictive pericarditis.
Main Methods:
- Coronary artery motion was assessed in normal subjects and patients with constrictive pericarditis, congestive cardiomyopathy, restrictive cardiomyopathy, and coronary artery disease.
- Epicardial involvement was examined in constrictive pericarditis patients undergoing pericardial stripping.
Main Results:
- Seven of eight patients with constrictive pericarditis exhibited absent major coronary artery motion.
- Patients with congestive cardiomyopathy, restrictive cardiomyopathy, and coronary artery disease generally showed normal coronary artery motion.
- Epicardial involvement in constrictive pericarditis correlated with regions of absent coronary artery motion.
Conclusions:
- Absent coronary artery motion may serve as a diagnostic sign for constrictive pericarditis, especially in ambiguous cases.
- This finding can help differentiate constrictive pericarditis from restrictive cardiomyopathy, which shares similar hemodynamic profiles.
Abstract:
Coronary artery motion was evaluated in normal subjects and patients with constrictive pericarditis (CP), congestive cardiomyopathy, restrictive cardiomyopathy, and coronary artery disease. Seven of the 8 patients with CP had lack of motion of the major coronary arteries. Nine of the 10 patients with congestive cardiomyopathy and a markedly reduced ejection fraction showed normal motion, as did all 4 with restrictive cardiomyopathy and 9 of the 10 with segmental dysfunction due to coronary disease. Pericardial stripping in 5 patients with CP revealed epicardial involvement corresponding to regions of absent motion; one CP patient with normal motion had no epicardial involvement. Lack of motion may suggest CP when the diagnosis is unsuspected, right heart pressures are not obtained, or hemodynamics are atypical. This sign may also help to distinguish CP from restrictive cardiomyopathy, which produces similar hemodynamics.
