Objectives: To determine the benefit of adding chest scanning to the routine echocardiographic examination to diagnose pleural effusions. Background: Pleural effusions are common in several cardiac disorders, yet routine echocardiography is insensitive in delineating pleural fluid. Methods: Bilateral chest scanning was performed in addition to the routine echo examination in 100 consecutive inpatients referred for echocardiography with recent chest X rays (CXRs). Detection and quantification of pleural effusion by sonographic chest scanning was compared blindly with CXRs. Identification of pleural fluid was analyzed for correlation with clinical diagnosis of congestive heart failure (CHF) and elevated pulmonary artery pressures if found by echo‐Doppler examination. Results: Agreement on presence or absence of pleural effusion occurred in 88 of 100 patients—in 5 patients bilateral chest scanning detected pleural effusion with negative CXRs; in 7 patients CXRs suggested pleural effusion with negative bilateral chest scanning (all 7 patients had minor blunting of the costophrenic angle). Routine echo views only detected 22 of 51 patients (43%) with pleural effusion detected by bilateral chest scanning. In 45 patients with CHF, 29 (64%) had pleural effusion by bilateral chest scanning (25 bilateral, 1 left, 3 right) vs 12 (27%) by routine echo (only left pleural effusion seen). Ejection fraction and estimated pulmonary artery pressure did not differ between CHF patients with and without pleural effusion. Conclusions: Routine echocardiographic views underestimate the presence of pleural effusion in patients referred for study. Bilateral chest scanning is equal to CXRs for pleural effusion detection and provides clinically useful information which may be of particular benefit to patients with CHF.
