Abstract

Introduction Atrioventricular conduction disorders are the most important common problems after cardiac surgeries, which may need pacemaker implantation. This may increase morbidity, mortality and hospital stayment. We studied the AV conductive disorders and their risk factors in patients who underwent cardiac surgery for different reasons. Materials and Methods A total of 400 cases that underwent cardiac surgery at Emam Reza hospital during the first half of 2006 were evaluated for time of onset and duration of AV block after surgery and need for pacemaker implantation during hospitalization. Results 43t of cases was female and 53 were male. CABG, VSD, ASD and PDA closure surgery were the most common procedures.38 had congenital heart diseases and 62 had acquired heart diseases. Permanent Pacemaker was needed in 1.3. First degree AV block was the most common type (17.8). Complete AV block was observed in all patients who underwent surgery for AV canal repairment. Occurrence of AV blocks was less common after CABG, but more frequent following surgery for congenital heart diseases. AV blocks, prolonged hospital stayment and need for permanent pacemaker. Multi-vessel coronary artery disease especially with RCA involvement, low EF and digoxin accompanied with increased risk of AV block. Conclusion Complete AV block is an important, but rare complication of cardiac surgery. This complication occurs more frequently after surgery for congenital heart disease that may need permanent pacemaker, prolonged hospital stayment and has increased morbidity.
