Final answer:
In systemic lupus erythematosus, echocardiographic/Doppler findings commonly include pericarditis, which involves inflammation and potential fluid around the heart, and Libman-Sacks endocarditis, leading to valvular abnormalities.
Step-by-step explanation:
Common echocardiographic/Doppler findings in systemic lupus erythematosus (SLE) are diverse due to the disease's effects on multiple organ systems, particularly the cardiovascular system. In SLE, one can expect to find pericarditis as a common manifestation. Pericarditis can be evidenced by the enlargement of the pericardial space or increased pericardial fluid on an echocardiogram. SLE may be associated with Libman-Sacks endocarditis which is characterized by valvular abnormalities like thickening or vegetation typically on the mitral valve or, less commonly, the aortic valve. However, it is not typically associated with aortic dissection, granular appearance of the myocardium, or valvular aortic stenosis, which are seen in other cardiovascular conditions.
