Objective: As invasive cardiovascular care has become increasingly complex, cardiac perforation leading to hemopericardium is a progressively prevalent complication. We sought to assess the frequency, etiology, and outcomes of hemorrhagic pericardial effusions managed through a nonsurgical echo-guided percutaneous strategy. Patients and Methods: Over a 10-year period (January 1, 2007, to December 31, 2016), 1097 unique patients required pericardiocentesis for clinically important pericardial effusions. Of these 411 had drainage of hemorrhagic effusions (defined as a pericardial hemoglobin level >50% of serum hemoglobin or frank blood in the setting of cardiac perforation). Clinical characteristics, echocardiographic data, details of the procedure, and outcomes were determined. Results: Median patient age was 67 years (interquartile range, 56-76 years), and 60% were men. The procedure was emergent in 83% and elective in 17%. The site of pericardiocentesis was determined by echo-guidance in all: 68% from the left para-apical region, 18% from the left or right parasternal areas, and 14% were subxyphoid. Half (n=215 [52%]) occurred after cardiac perforation with percutaneous interventional procedure (ablation, n=94; device lead implantation, n=65; percutaneous coronary intervention, n=22; other, n=34), whereas 30% followed cardiac or thoracic surgery. Pericardial fluid volume drained was 546±440 mL. In 94% of cases, echo-guided pericardiocentesis was the only treatment of the effusion needed, whereas definitive surgery was required in 25 (6%) cases for persistent bleeding or acute management of the underlying etiology. There was no procedural mortality. Late mortality was better for hemorrhagic effusions compared with a contemporary cohort with nonhemorrhagic effusions. Conclusion: Echocardiographic guidance allows rapid successful pericardiocentesis in the setting of hemopericardium related to microperforation with interventional procedures, malignancy, or pericarditis, with most not requiring surgical intervention. Surgery should remain the first-line approach for aortic dissection or myocardial rupture.
