title: [A study of pacemaker implantation to cases performed valve surgery].
abstract: For 13 years between 1980 and 1992, 23 patients needed pacemaker (PM) implantation because of bradyarrhythmia, 21 of atrial fibrillation and two of complete A-V block, after valve surgery. Five of 88 survivors (5.7%) after OMC, 11 of 227 (4.8%) after MVR, one of 169 (0.6%) after AVR, five of 67 (7.4%) after MVR + AVR and one of 15 (6.7%) after TVR underwent PM implantation in postoperative period. Two cases who had heart failure was implanted PM in early postoperative period. In late period, the mean duration between previous valve surgery and PM implantation was 6.4 years in 12 cases after initial valve surgery and 2.3 years in nine after second valve surgery. Postoperative course after PM implantation was almost good, but one case was died due to critical arrhythmia. And one case underwent re-MVR because of mitral bioprosthesis dysfunction and one, without anticoagulant after OMC, was complicated cerebral infarction.
