PURPOSE:  Prevalence of pericardial effusion in patients with left ventricular dysfunction is not known. The goal of this study was to evaluate the prevalence and severity of pericardial effusion in patients with decreased fractional shortening (FS) using a large echocardiography data Base.

METHODS:  We retrospectively analyzed 24,265 echocardiograms performed at our institution between 1984 and 1998. FS were recorded in 18,015 echocardiograms. We correlated the occurrence of pericardial effusion with the degree of fractional shortening. We stratified FS in 4 groups ( 1. FS > 25%, 2. FS between 17.5 and 25%, 3. FS between 10 and 17.5 % and 4. FS < 10%.) Effusion was divided in 3 groups (mild, moderate and severe).

RESULTS:  Pericardial effusion was present in 1,632 (9.1%) of echocardiograms with documented FS. Pericardial effusion was significantly more common in patients with FS < 25 % and correlated with the severity of decreased FS (group 1: 8.4%, group 2: 12,8%. group 3: 13.2%, group 4: 14.4%, p<0.0001). However, only mild pericardial effusion was correlated with low FS (group 1: 6.6%, group 2: 11.0%. group 3: 11.1%, group 4: 14.0%, p<0.0001).

CONCLUSION:  Decreased left ventricular systolic function correlates with only mild pericardial effusion. Therefore, moderate or severe pericardial effusion can not be explained by decreased LV systolic Function.

CLINICAL IMPLICATIONS:  Occurence of moderate to large effusion can not be secondery to left ventricular dysfunction.
