[Surgical treatment of left atrial myxoma with concomitant acquired heart disease].
Among 21 patients with left atrial myxoma treated during the past 11 years in our institute, 3 patients had associated acquired heart disease which required concomitant cardiac surgery. Two patients had atherosclerotic coronary arterial disease, and underwent single coronary artery bypass grafting (CABG) and 4 CABGs in addition to removal of myxoma, respectively. Both of them received CABGs after removal of myxoma, because the intraoperative heart protection using retrograde coronary perfusion could afford the situation. Another patient had a huge left atrial myxoma associated with mitral and tricuspid regurgitation. She suffered from sudden heart failure caused by tumor obstruction of blood flow across the mitral valve, and an emergency surgery was performed. She underwent mitral valve replacement for annular dilatation with prolapse of both leaflets and tricuspid annuloplasty for annular dilatation, in addition to removal of myxoma. All of these 3 patients went a good postoperative course and are doing well now with no local recurrence. In this paper, preoperative and intraoperative evaluation, and surgical treatment of associated heart disease with left atrial myxoma were discussed.
