Özet
Background: Coronary artery disease is one of the most common causes of complete atrioventricular block (AVB) in adults. In this study, we evaluated whether prompt revascularization of the coronary artery occlusion can ameliorate newonset complete AVB due to acute coronary syndrome (ACS). Methods: Five patients (4 men and 1 woman) with a mean age of 69.8 +/- 7.1 years with diagnosed new-onset complete AVB and proven coronary artery disease were enrolled in the study. At the time of AVB diagnosis, 3 of the patients had acute myocardial infarction, and the other 2 patients had unstable angina pectoris. All patients underwent complete coronary bypass surgery after the diagnosis of complete AVB. A patient who underwent 2 coronary bypasses also underwent aortic valve replacement. Results: No mortality was observed in the study group. All but one of the patients converted back to sinus rhythm after a mean interval of 30 +/- 13.6 hours following revascularization procedures. Complete AVB persisted in 1 patient, and a permanent pacemaker was implanted. All patients were discharged uneventfully. The mean hospital stay was 11.4 +/- 4.5 days. All patients are still being followed up after surgery; at a mean follow-up of 27.4 +/- 0.9 months, there have been no further problems. Conclusion: Coronary revascularization may ameliorate ACS-related new-onset complete AVB with an acceptable rate of successful reversion to sinus rhythm. An especially appropriate time for surgery, complete coronary revascularization, and management of myocardial protection during surgery might improve the results of coronary bypass procedures in these patients.
