Pericardial pacing wire placement may occasionally result in intravascular or intratracheal wire migration, infective endocarditis, and sepsis; reportedly, the incidence of complications is approximately 0.09 to 0.4%. We report a case of a retained epicardial pacing wire that migrated into the pulmonary artery. A 66-year-old man underwent coronary artery bypass grafting for angina pectoris, with placement of an epicardial pacing wire on the right ventricular epicardium, 6 years prior to presentation. Some resistance was encountered during wire extraction; therefore, it was cut off at the cutaneous level on postoperative day 8. Computed tomography performed 6 years postoperatively revealed migration of the pacing wire into the pulmonary artery, and it was removed using catheter intervention. Surgeons should be aware of complications associated with retained pacing wires in patients in whom epicardial wires are retained after cardiac surgery.

A 64-year-old woman was admitted to our hospital with sudden chest and back pain. Computed tomography showed acute type A aortic dissection complicated with malperfusion of the left main coronary artery (LMT). Immediately after the CT, the patient went into sudden shock. Electrocardiogram showed ventricular tachycardia and ventricular fibrillation. Percutaneous cardio-pulmonary support was administered and coronary arteriogram (CAG) was performed. CAG revealed LMT stenosis and intravascular ultrasound showed mobile intimal flap at the LMT. Percutaneous coronary intervention of the LMT was performed. The patient recovered from shock and was treated with ascending aorta replacement with CABG. The patient was discharged from the hospital without any major complication.
