Brain and lower body protection during aortic arch surgery.

Background: Deep hypothermic circulatory arrest (DHCA) at ≤20°C for aortic arch surgery has been widely used for decades, with or without cerebral perfusion (CP), antegrade (antegrade cerebral perfusion [ACP]), or retrograde. In recent years nadir temperature progressively increased to 26°C-28°C (moderately hypothermic circulatory arrest [MHCA]), adding ACP. Aim of this multicentric study is to evaluate early results of aortic arch surgery and if DHCA with 10 min of cold reperfusion at the same nadir temperature of the CA before rewarming (delayed rewarming [DR]) can provide a neuroprotection and a lower body protection similar to that provided by MHCA + ACP.

Minimally invasive tricuspid valve surgery without caval occlusion: Short and midterm results.

Objective: The use of minimally invasive or transcatheter interventions rather than standard full sternotomy operations to treat tricuspid valve (TV) disease is increasing. The debate however is still open regarding venous drainage management during cardiopulmonary bypass (CPB) and wheatear or not superior and inferior vena cava should be occluded during the opening of the right atrium to avoid air entrance in the venous line. The aim of the present study is to report operative outcomes and midterm follow-up results of minimally invasive TV surgery performed without caval occlusion.

Prevalence and Clinical Impact of Systemic Inflammatory Reaction After Cardiac Surgery.

Objectives: Cardiac surgery induces a systemic inflammatory reaction that has been associated with postoperative mortality and morbidity. Many studies have characterized this reaction through laboratory biomarkers while clinical studies generally are lacking. This study aimed to assess the incidence of postoperative systemic inflammation after cardiac surgery, and the association of postoperative systemic inflammation with preoperative patients' characteristics and postoperative outcomes.
