Why the study?
Does the extended trans-septal approach compared to the left atrial approach affect the incidence of postoperative arrhythmias in patients undergoing mitral valve surgery?
Does the extended trans-septal approach compared to the left atrial approach affect the incidence of postoperative arrhythmias in patients undergoing mitral valve surgery?
The surgical approach (extended trans-septal vs left atrial) for mitral valve surgery independently predicts the development of postoperative ectopic atrial or junctional rhythm.
Extended trans-septal approach associated with ectopic rhythms after mitral surgery; leaves open optimal technique pending randomized confirmation.
This study was undertaken to determine the incidence of postoperative arrhythmias in mitral valve surgery through the left atrium as compared with the extended trans-septal approach. All patients undergoing mitral valve surgery for acquired valve disease between 1 January 1991 and 31 December 1993 were reviewed. Only patients with preoperative normal sinus rhythm were included in this study. End-points for analysis were: ‘any supraventricular arrhythmia’; ‘atrial fibrillation or flutter’; and ‘ectopic atrial or junctional rhythm’. All predictive factors with a P-value <0.10 in univariate analysis were entered into the multivariate proportional hazard model of Cox. Some 72 patients were included for analysis. No variables were independently predictive of ‘any supraventricular arrhythmia’. Age is an independent predictor of ‘atrial fibrillation or flutter’ and surgical approach of ‘ectopic atrial or junctional rhythm’.
