Task: Answer Verification
Input (English): Question: Does preservation of the right atrial appendage improve reduced plasma atrial natriuretic peptide levels after the maze procedure?
Answer: The present study showed that preservation of the right atrial appendage lessens the decrease of plasma atrial natriuretic peptide levels after the maze procedure and that increased plasma atrial natriuretic peptides may improve the ability of the kidneys to excrete the fluid load after the operation.
Output (English): yes
