Although other factors may contribute, left atrium size has been found to be a predictor of mortality due to both cardiovascular issues as well as all-cause mortality. Mitral valve prolapse may not cause any symptoms. Figure 1. High blood pressure and blood volume cause right atrial enlargement. The right atrium must then enlarge (hypertrophy) in order to manage to pump blood into the right ventricle. The left atrial index was also higher in the hypertensive group, 2.18 +/- 0.45 versus 1.88 +/- 0.10 cm/m2 (p less than 0.05), and the left atrial-to-aortic root dimension ratio was significantly higher in the hypertensive group, 1.36 +/- 0.20 versus 1.17 +/- 0.07 (p less than 0.01).
