Background and Goal of StudyCardiac surgery has shown higher difficult intubation (DI) rates compared to other kind of surgeries [1][2] . Older age, male gender, morbid obesity and dental problems have been associated with these findings [1][3] . The aim of this study is to describe the prevalence of DI in cardiac procedures in our centre, as well as to analyze wether parameters as gender, age, body mass index (BMI) and type of surgery (valve replacement (VR) or coronary artery bypass (CAB)) could be predictors of DI in our population.
