Review Meta AnalysisNitric Oxide in Cardiac Surgery: A Meta-Analysis of Randomized Controlled Trials.
To investigate the efficacy and safety of perioperative administration of nitric oxide in cardiac surgery. ⋯ Perioperative delivery of inhaled nitric oxide resulted to be of no or minimal benefit in patients with pulmonary hypertension undergoing cardiac surgery. Large, randomized trials are needed to further assess its effect on major clinical outcomes and its cost-effectiveness.

Observational StudyImpella Placement Guided by Echocardiography Can Be Used as a Strategy to Unload the Left Ventricle During Peripheral Venoarterial Extracorporeal Membrane Oxygenation.
At the authors' institution, before 2015, patients cannulated for peripheral venoarterial extracorporeal membrane oxygenation (VA-ECMO) did not undergo left ventricular (LV) decompression with the use of an LV vent. After 2015, the authors' institution began using the Impella device to vent the left ventricle in patients on VA-ECMO. The authors hypothesized that survival outcomes would improve in patients on VA-ECMO with the use of an Impella for LV venting. ⋯ Patients on VA-ECMO plus Impella implantation demonstrated improved survival compared with patients treated with VA-ECMO alone. Key echocardiographic characteristics such as improved LV function after Impella placement and LV cavity size reduction during therapy may help predict those patients who may benefit most from this cannulation strategy.

Randomized Controlled TrialA Trial of Two Anesthetic Regimes for Minimally Invasive Mitral Valve Repair.
Minimally invasive mitral valve repair may be associated with prolonged cardioplegic arrest times and ischemic reperfusion injury. Intravenous (propofol) and volatile (sevoflurane) anesthesia are used routinely during cardiac surgery and are thought to provide cardioprotection; however, the individual contribution of each regimen to cardioprotection is unknown. Therefore, the authors sought to compare the cardioprotective effects of propofol and sevoflurane anesthesia in patients undergoing minimally invasive mitral valve repair. ⋯ Propofol and sevoflurane anesthesia were associated with similar degrees of myocardial injury, indicating comparable cardioprotection. Myocardial injury was related directly to the duration of cardioplegic arrest.
