Obstructive sleep apnea (OSA) is not generally acknowledged as a perioperative risk factor. High incidence of Sleep disordered breathing has been noticed in patients with cardiovascular disease. The Sleep Heart Health Research Study Group found Apnea-Hypopnea indices (AHI) as modest as 1-10 to be associated with cardiovascular disease manifestations. Given the lack of data we chose to study the incremental risk of OSA in patients undergoing cardiac surgery. ⋯ | Increased risk for postoperative complications is suggested in patients with OSA undergoing cardiac surgery. This risk is underestimated on account of lack of awareness about the incidence of OSA in the general population and the cardiovascular population in particular, difficulties in clinical suspicion and diagnosis and limited use of polysomnography.

The avoidance of cardiopulmonary bypass and aortic cross-clamping in patients possessing single ventricular physiology has potential advantages including preservation of ventricular and pulmonary functions; early extubation, decreased incidence of pleural effusions and decreased requirement of inotropic agents and blood products. In this study, we assessed the postoperative outcome of patients who have undergone extracardiac Fontan operation performed without cardiopulmonary bypass. ⋯ The extracardiac Fontan operation performed without cardiopulmonary bypass provides good results in short and midterm follow-up periods with improved postoperative hemodynamics.

Randomized Controlled Trial
Effect of cold blood cardioplegia enriched with potassium-magnesium aspartate during coronary artery bypass grafting.
The aim of this investigation is to evaluate the effect of enriched with potassium-magnesium aspartate cold-blood cardioplegia on early reperfusion injury and postoperative arrhythmias in patients with ischemic heart disease undergoing coronary artery bypass grafting (CABG), using measurements of cardiac troponin I (CTnI), hemodynamic indexes and clinical parameters. ⋯ Cold blood cardioplegia enriched with potassium-magnesium aspartate is beneficial on reducing reperfusion injury.

Comparative Study
Risk factor analysis for ascending aorta and aortic arch repair using selective cerebral perfusion with open technique: role of open-stent graft placement.
The present study was designed to identify risk factors that may induce adverse outcome defined as permanent neurological dysfunction and mortality after aortic arch surgery using selective cerebral perfusion by logistic regression analysis and to reveal the role of open stent-graft placement. ⋯ Thoracotomy was significant risk factor for adverse outcome after aortic arch repair using selective cerebral perfusion. Total arch replacement with open stent-graft placement can avoid the need of thoracotomy and reduce time variables concerning the operation to improve the surgical
