Abstract:

Objective To describe the clinical presentation，diagnostic workup，and management of purulent pericarditis occurring after percutaneous coronary intervention （PCI），and to summarize relevant literature to provide clinical guidance. Methods We performed a retrospective case analysis of a patient who developed purulent pericarditis after PCI and conducted a targeted review of published reports on post PCI purulent pericarditis. Results An elderly male with a long history of intermittent chest tightness for over 20 years presented with worsening chest pain for 4 days. PCI had been performed shortly before symptom onset. Significant comorbidities included advanced age，diabetes mellitus，and recent herpes zoster infection. Transthoracic echocardiography and chest CT revealed a pericardial effusion. The patient underwent pericardiocentesis drainage，pericardial lavage with saline and antibiotics，and systemic intravenous antibiotics，resulting in clinical improvement. At one month outpatient follow up，the patient was clinically well，and echocardiography showed resolution of the effusion. Conclusion Prompt recognition，pericardial drainage，and early，aggressive antimicrobial therapy are crucial for favorable outcomes of purulent pericarditis.
