Result: Trace mitral regurgitation. --Right Upper Quadrant Ultrasound. Results: The upper abdominal aorta and IVC are unremarkable but these structures are incompletely visualized. -- Venous Duplex- Bilateral Lower Ext. Result: no evidence of deep vein thrombosis. --Complete Echo. Result: LVEF 45%; Decreased left ventricular cavity size.

Mild aortic valve leaflet thickening. Trace mitral regurgitation. Mild tricuspid regurgitation. No pericardial effusion. Normal atrial septum by 2D and color Doppler. Normal aortic root diameter for body size. Small ascending aorta. --Cardiac MRI. Results: Overall appearance suggestive of perimyocarditis. Recommend follow-up cardiac MRI in 3 months.
