Thalassemia is an inherited hemoglobin disorder characterized by hemolytic anemia. Reportedly, cardiopulmonary bypass (CPB) causes hemolysis; therefore, extreme caution is warranted during CPB. However, few studies have reported open heart surgery in patients with thalassemia. We report successful surgery for aortic stenosis and regurgitation (ASR) and an ascending aortic aneurysm (AsAA) in a patient with thalassemia. A 69-year-old woman was referred to our hospital for surgical management of ASR and AsAA. Comprehensive evaluation of microcytic anemia led to diagnosis of beta-thalassemia minor. We performed aortic valve and ascending aorta replacement; we used a biologic valve and performed open distal anastomosis under hypothermic circulatory arrest (25°) combined with retrograde cerebral perfusion. Non-pulsatile flow circulation was maintained using a centrifugal pump during CPB. The suction and ventilatory pressures were decreased, and we performed dilutional ultrafiltration. A spare artificial lung was connected to the CPB to avoid complications in the event of artificial lung blockage. We did not observe any hemolysis-induced adverse event during the clinical course, and the patient was discharged 20 days postoperatively. Careful preoperative evaluation is essential to confirm thalassemia before cardiovascular surgery to establish an optimal surgical strategy and avoid the risk of CPB-induced hemolysis in patients with the hematological disorder.

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.
