Abstract: Abstract Background: Ventricular tachyarrhythmia (VT/VF) after aortic artery cross clamp release in cardiac surgery iscommon and the occurrence has been described but the incidence and risk factors are not well defined. This study wasdesigned with the aim to evaluate the prevalence of VT/VF after aortic cross clamp release and to identify risk factors of patients developing such arrhythmias. Methods: A retrospective observational study 1052 patients over a period of 12 months from March 2011 toFebruary 2012 undergoing various cardiac surgeries with aortic cross clamp were monitored for new-onset ventricular tachyarrhythmia intraoperatively. Results: The prevalence of ventricular tachyarrhythmia was 24.4%. We found age above 30 years, increasing body massindex (BMI), valvular surgeries and male gender as risk factors for VT/VF after cross clamp release in cardiac surgeries. Conclusions: Ventricular tachyarrhythmia is common following all cardiac surgeries, especially valvular heartdiseases. There is a strong relationship between ventricular arrhythmias and age above 30 years, coronary arterybypass surgery (CABG), high (BMI) and male gender. It is essential for intense monitoring of these patients.
