Abstract
Fifty-two normally pregnant women underwent echocardiography to examine their pericardium in the first, second and third trimester. Pericardial effusion was noted in 15.3% of the women (n=8) in the first trimester, 19.2% (n=10) in the second trimester and 44.2% (n=23) in the third trimester of pregnancy. Pericardial effusion during pregnancy was found to be completely resolved in all patients who underwent an echocardiogram 6 weeks post delivery (n=U). There was no statistically significant difference in age, hemoglobin, total protein, albumin/globulin ratio or mean blood pressure during pregnancy between those who developed pericardial effusion and those who did not. The frequency of occurrence of pericardial effusion in primigravidas at 69.2% (9/13) was higher than that in multigravidas, with a ratio of 35.9% (14/39), the difference being statistically significant (p < 0.025). The frequency of occurrence of pericardial effusion in patients who gained more than 12 kg during pregnancy at 67.7% (11/17) was higher than in patients who gained less than 12 kg, with a ratio of 34.3% (12/35), the difference being statistically significant (p < 0.025).
