[Cardiovascular surgery with multiple myeloma].

There are few case reports of cardiovascular surgery with multiple myeloma. We report 3 cases of cardiovascular surgery with multiple myeloma. CASE 1: A 73-year-old male hemodialytic patient with multiple myeloma was performed off-pump coronary artery bypass grafting (OPCAB) for angina. He was dead on the 72th postoperative day because of sepsis. CASE 2: A 68-year-old female patient with multiple myeloma was performed mitral valve replacement for mitral regurgitation. The postoperative course was uneventful. CASE 3: A 78-year-old male patient, the aorta was replaced with a artificial graft for impending rupture of thoracoabdominal aortic aneurysm. He was diagnosed with multiple myeloma after surgery. He was dead on the 99th postoperative day because of sepsis. One of the affecting prognosis factors is infection and it is intractable.
