INTRODUCTION: This study aimed to investigate the causes, clinical management and outcomes of clinically significant pericardial effusions, and evaluate the practice of pericardiocentesis within an academic medical centre in Singapore, a multiethnic country in Southeast Asia.
METHODS: Consecutive patients undergoing pericardiocentesis at a single Asian academic medical centre were identified. Patient demographics, echocardiographic findings, investigations, pericardiocentesis procedural details and clinical progress were tracked using a comprehensive electronic medical records system.
RESULTS: Of 149 patients who underwent pericardiocentesis, malignancy (46.3%) was the most common cause of pericardial effusions, followed by iatrogenic postsurgical complications (17.4%). 77.3% of effusions were large and 69.8% demonstrated tamponade physiology. Pericardiocentesis guided by echocardiography and fluoroscopy was successful in 99.3% of patients and had a complication rate of 2.0%. Likelihood of effusion recurrence and survival to discharge was determined by the aetiology of the pericardial effusion. 24.6% of malignant effusions recurred, and the survival rate 12 months after drainage of a malignant pericardial effusion was 45.0%. Short-term mortality was highest among patients presenting with tamponade due to acute aortic syndromes and those with myocardial rupture due to ischaemic heart disease.
CONCLUSION: Cancer and iatrogenic complications were the most common causes of pericardial effusion in this large cohort of Singapore patients. Pericardiocentesis has a high success rate and relatively low complication rate. Prognosis and clinical course after pericardiocentesis are determined by the underlying cause of the pericardial effusion.
