Ventricular fibrillation (VF) is a complete desynchronization of ventricular fibers due to multiple reentry wavelets. The aim our study was determine the frequency as well risk factors for occurrence VF after aortic decompression intraoperatively in cardiac surgery. This prospective observational study, conducted over period 06 months at CHU de Fann center. All patients scheduled surgery under extracorporeal circulation were included. Exclusion criteria with incomplete preoperative and/or intraoperative data. Our included 105 mean age 24.5 years and sex ratio 0.98. underwent compensated status. Intraoperatively, all had received general anesthesia tracheal intubation. duration clamping 93.8 min, half single dose cardioplegia. incidence reperfusion 16.2%, main being valve surgery, sildenafil use, left ejection fraction < 50%, severe pulmonary hypertension systolic artery pressure > 80mmHg. one most dreaded complications Preventive treatment amiodarone or lidocaine before releasing clamp would seem reduce its incidence. Hence importance recommending this measure daily practice.
