Randomized Controlled Trial Comparative Study
Comparison of the efficacy of the cardiac hypothermia and normothermia to myocardial damage in coronary artery bypass graft surgery with systemic normothermic cardiopulmonary bypass.
The aim of our research is to investigate the cardiac damage formed by either local cardiac hypothermia or cardiac normothermia technique in patients who undergone isolated coronary artery bypass graft (CABG) surgery. ⋯ Myocardial damage was less than in normothermia group according to hypothermia group. The results show that ice-cold blood cardioplegia and local ice treatment of the heart during CPB seems to harm the heart more than warm blood cardioplegia.

Comparative Study
Clinical outcome of the PAS-Port® proximal anastomosis system in off-pump coronary artery bypass grafting in 201 patients.
The PAS-Port® Proximal Anastomosis System (Cardica, Inc, Redwood City, CA, USA) has been used worldwide since March 2003. The objective of the present study was to evaluate the clinical outcome of the PAS-Port® Proximal Anastomosis System. ⋯ The clinical outcomes in patients treated with the PAS-Port® Proximal Anastomosis System were satisfactory compared with those treated with the conventional hand-sewing technique. The use of the PAS-Port system was not associated with higher adverse outcome in terms of overall survival, stroke, coronary reintervention-free survival and freedom from reintervention due to proximal vein graft failure.

Comparative Study
The use of N-terminal pro-brain natriuretic peptide as a predictor of atrial fibrillation after cardiac surgery.
Atrial fibrillation (AF) is the most common arrhythmia after cardiac surgery with cardiopulmonary bypass (CPB). The value of Nt-pro BNP in predicting AF complicating cardiac surgery is not well studied. Our objective is to determine its predictive role in the occurrence of this complication after heart surgery with cardiopulmonary bypass. ⋯ An early Nt pro BNP at H0 or H4, respectively, and with thresholds of 353 and 307 pg/mL could predict the occurrence of the AF. In this case, a primary prevention could be envisaged.

Multicenter Study
Females do not have increased risk of early or late mortality after isolated aortic valve replacement: results from a multi-institutional Australian study.
There is controversy regarding whether isolated aortic valve replacement (AVR) in women is associated with an increased risk of early and late mortality. The current study evaluates the impact of gender as an independent risk factor for early and late mortality after isolated AVR. ⋯ Female patients undergoing isolated AVR do not have an increased risk of early and late mortality. Further investigation is required to delineate the impact of gender on early and late outcomes following AVR.

Comparative Study
Single-center experience with endovascular treatment of acute blunt thoracic aortic injuries.
Endovascular repair of the thoracic aorta (TEVAR) has been recently considered an appealing alternative to open treatment of traumatic aortic injuries. However, the use of this technique in emergency is often limited by hemodynamic instability, severe associated lesions and unavailability of adequate materials. Dedicated stent-grafts are not currently available. We report our results in treating blunt traumas of the thoracic aorta using three different commercially available stent-grafts. METHODS Between 2003 and 2010, 28 patients (22 males, mean age 38.9±12.1 years) underwent TEVAR for a traumatic aortic lesion. A total-body computed tomography angiography (CTA) was performed in all cases to establish the diagnosis of aortic rupture and evaluate associated injuries. After TEVAR, patients were followed-up with CTA of the chest before discharge from the hospital, at 6 months and yearly thereafter. ⋯ In our experience, endovascular treatment of acute traumatic thoracic aortic injuries using different commercially available stent-grafts allows to obtain satisfactory short term results.
