In adults, reservoir PS correlates positively with LV filling pressure in LV systolic dysfunction [14]; predicts LV late remodeling after acute coronary syndrome [15]; falls immediately after cardioversion, reflecting atrial stunning [16]; falls in mitral or aortic valve disease [17, 18]; and correlates negatively with levels of brain natriuretic peptide n-terminal prohormone [19]. Here, NPPB is linked to aortic valve disorder.
