title: [Cardiac Amyloidosis Diagnosed Following Mitral Valve Repair; Report of a Case].
abstract: We present a case of a 60-year-old female who underwent elective mitral valve repair for mitral valve regurgitation. Intra-aortic balloon pumping was necessary to wean her from cardiopulmonary bypass, and a sudden cardiac arrest happened on postoperative day 17. Due to such unexpected postoperative course, a right ventricular biopsy was done, and she was diagnosed with light chain amyloidosis (AL) type cardiac amyloidosis. Despite long percutaneous cardiopulmonary bypass support, she never recovered from severe heart failure. Cardiac surgeons should be aware of this fatal disease, and preoperative screening with various tests is required.
