Analysis of clinical, echocardiographic, microbiological and cytopathological characteristics of pericardial effusions in a tertiary hospital care. Arch. Cardiol. Méx.

Objective: To determine the prevalence, etiology, clinical, echocardiographic, microbiological and cytopathological characteristics of patients with pericardial effusion. Methods: Observational, retrospective, cross-sectional analytical study. We reviewed medical records of patients undergoing pericardiocentesis for a 5 years period. We used descriptive statistics, measures of central tendency and dispersion for analysis. Results: The prevalence of pericardial effusion was 1.1%. Predominant in women (60.4%) and there was a mean age of 49 years. The main causes were neoplastic 32.1%, idiopathic 27.4% and rheumatological 10.4%. A percentage of 27.1 had cardiac tamponade whereas dyspnea and muffled heart sounds were the most common clinical data. The right atrial and ventricular collapse occurred in 84.9 and 75.5%, respectively. The pericardial fluid cytology yielded better in neoplastic causes a sensitivity of 54%, specificity 95%, positive predictive value 85% and negative predictive value 81%. Conclusions: The prevalence of pericardial effusion in a tertiary care hospital was 1.1%, the main cause was neoplastic. In the evaluation of moderate or severe pericardial effusion we found that right atrial and ventricular collapses were the most common echocardiographic findings. The cytopathological study had a high specificity for the diagnosis of neoplasia.
