Updates to Study Attributes
Findings:
Heart rate: 49 bpm, BSA: 2,01 m²
Image quality:some respiratory movement during the T1 mapping
Morphology and functional analysis:
- LV-EDVI: 74
mlmL/m² - LV-ESVI: 29
mlmL/m² - LV-SVI: 45
mlmL/m² - LV-EF: 60%
- Cardiac output: 4.4
lL/min - Cardiac index: 2
,2 l.2 L/min/m² - LV-ED mass + papillary muscle: 67 g/m²
- Septum thickness: 10 mm
No regional left ventricular wall motion abnormalities.
Visually normal atrial size.
No intercavitary thrombi found.
Myocardial tissue properties:
No regional or global myocardial oedema.
No subendocardial, intramyocardial or subepicardial late gadolinium enhancement is visible.
T1 mapping native: 1005±28 ms [948-1060ms-1060 ms*], extracellular volume (ECV): ≈ 26,3.3%
*native T1 reference range based on local data
Moderate circular pericardial effusion.
Pericardial enhancement. Pericardial thickening (3-4mm-4 mm).
Small bilateral pleural effusions.
Impression:
ExtensiveModerate pericardial effusion and pericardial enhancement indicating pericarditis.
No signs of acute myocardial inflammation.
Viable myocardium, no subendocardial scar seen.
Updates to Study Attributes
Late gadolinium enhancement (LGE):
No intramyocardial or subepicardial late gadolinium enhancement is seen.
Moderate pericardial effusion with pericardial enhancement and thickening (red arrowheads).
Good viability, especially in the anterior wall in the territory of the left anterior descending artery (LAD).
Short tau inversion recovery (STIR) imaging / early gadolinium enhancement (EGE):
Pericardial thickening and oedema (red arrows). No focal myocardial oedema can be seen.
T2 signal intensity ratio between myocardium and skeletal muscle within the same image was normal.
No signs of myocardial hyperaemia.
T1 mapping native and postcontrast:
native T1 ≈ 1005≈1005 ms, z-score of ≈0 (within normal limits)
The application of gadolinium leads to a shortening of T1.
Extracellular volume (ECV) was < 30% in all segments ≈ 26.3% (within normal Limitslimits)
Lateral chest x-Ray-ray:
Pericardial fat stripe also known as sandwich or oreo cookie sign:
The epicardial (red arrows) and paracardial fat (blue arrows) is separated by a “stripe” of increased density (light green *), representing pericardialpericardial fluid.
