Imaging findings
Chest radiographs and CT demonstrate extensive pericardial thickening and calcification. Cardiac MRI (four-chamber cine) reveals a characteristic interventricular septal bounce (septal shift during inspiration), bi-atrial enlargement, and a dilated inferior vena cava. No delayed myocardial enhancement is seen, and myocardial tagging sequences show preserved pericardial-myocardial motion.
Key takeaways
Constrictive pericarditis restricts diastolic filling due to a non-compliant pericardium. Key diagnostic features on cardiac MRI include bi-atrial dilatation, a dilated inferior vena cava, and a septal bounce during early diastole or inspiration, which represents ventricular interdependence and helps differentiate constriction from restrictive cardiomyopathy.
