Demonstrates that C. acnes can cause purulent pericarditis after CABG and highlights the utility of TEE when TTE is unrevealing in symptomatic postoperative patients.
Consider C. acnes in post-CABG pericarditis; single case leaves open need for prospective data.
Cutibacterium acnes is a gram-positive, anaerobic rod commonly found on the skin and mucosal membrane. It is mostly associated with its role in acne formation, but here we present a case of purulent pericarditis secondary to C. acnes after coronary artery bypass graft surgery (CABG). A 58-year-old male presented for CABG after a coronary angiogram showed severe multivessel disease. The procedure was performed successfully. He had minimal complications until postop day seven, when he developed a fever and hypoxia. The transthoracic echo (TTE) was largely unrevealing. Due to further declining status the following day, a transesophageal echo (TEE) was performed and revealed a loculated pericardial effusion not visualized on TTE. This was subsequently drained, and fluid cultures grew C. acnes. The patient received five weeks of antibiotic therapy, which improved his condition.
