Аннотация
BACKGROUND: Cardiac tamponade due to perforation of a cardiac chamber is a rare complication occurring in only 0.3% of patients undergoing permanent pacemaker (PM) implantation. Notably, perforation of the right coronary artery (RCA) following permanent PM implantation has only been reported twice in the literature. We report a rare case of RCA perforation leading to life-threatening cardiac tamponade with symptom onset 4 days after PM implantation.
CASE SUMMARY: A 75-year-old woman underwent permanent PM implantation without any difficulties in placing pacemaker leads and with good thresholds. Four days later, the patient was readmitted in a state of shock due to cardiac tamponade. A blood gas analysis on the bloody pericardial effusion raised suspicion of ongoing arterial bleeding. A CT scan ruled out aortic dissection; instead, the source of bleeding was identified as a perforation in the RCA, which was managed surgically.
DISCUSSION: This case highlights the necessity of coronary artery perforation being among the differential diagnoses of cardiac tamponade after PM implantation, and it stresses the usefulness of performing a blood gas analysis on the bloody pericardial effusion.
