Review Meta AnalysisVentilator-associated pneumonia after cardiac surgery: a meta-analysis and systematic review.
Ventilator-associated pneumonia (VAP) is the most common and serious nosocomial infection that threatens patients who have undergone cardiac surgery. This article summarizes its clinical characteristics and provides theoretical evidence for prevention and treatment. ⋯ VAP in patients after cardiac surgery is common and has a poor prognosis. It is mainly caused by gram-negative bacteria, and could be affected by a series of factors.

Randomized Controlled Trial Multicenter StudyMyocardial viability and impact of surgical ventricular reconstruction on outcomes of patients with severe left ventricular dysfunction undergoing coronary artery bypass surgery: results of the Surgical Treatment for Ischemic Heart Failure trial.
In the Surgical Treatment for Ischemic Heart Failure trial, surgical ventricular reconstruction plus coronary artery bypass surgery was not associated with a reduction in the rate of death or cardiac hospitalization compared with bypass alone. We hypothesized that the absence of viable myocardium identifies patients with coronary artery disease and left ventricular dysfunction who have a greater benefit with coronary artery bypass graft surgery and surgical ventricular reconstruction compared with bypass alone. ⋯ In patients with coronary artery disease and severe regional left ventricular dysfunction, assessment of myocardial viability does not identify patients who will derive a mortality benefit from adding surgical ventricular reconstruction to coronary artery bypass graft surgery.

Multicenter Study Comparative StudySociety of Thoracic Surgeons 2008 cardiac risk models predict in-hospital mortality of heart valve surgery in a Chinese population: a multicenter study.
The Society of Thoracic Surgeons 2008 cardiac surgery risk models have been developed for heart valve surgery with and without coronary artery bypass grafting. The aim of our study was to evaluate the performance of Society of Thoracic Surgeons 2008 cardiac risk models in Chinese patients undergoing single valve surgery and the predicted mortality rates of those undergoing multiple valve surgery derived from the Society of Thoracic Surgeons 2008 risk models. ⋯ The Society of Thoracic Surgeons 2008 cardiac surgery risk models performed well when predicting the mortality for Chinese patients undergoing valve surgery. The Society of Thoracic Surgeons 2008 models were suitable for single valve surgery in a Chinese population; estimates of mortality for multiple valve surgery derived from the Society of Thoracic Surgeons 2008 models were less accurate.

Multicenter Study Comparative Study Observational StudyMinimally invasive aortic valve replacement with Perceval S sutureless valve: early outcomes and one-year survival from two European centers.
The aim of our study was to evaluate the early outcomes and 1-year survival of patients undergoing minimally invasive aortic valve replacement with the Perceval S sutureless valve for severe aortic stenosis. ⋯ Minimally invasive aortic valve replacement with the Perceval S sutureless valve in high-risk patients is a safe and reproducible procedure associated with excellent hemodynamic results, postoperative outcomes, and 1-year survival.

Comparative StudyPilot study of pulmonary arterial branch sealing using energy devices in an ex vivo model.
Vascular endostaplers are bulky and can be dangerous when dividing small pulmonary arterial (PA) branch vessels during video-assisted thoracoscopic lobectomy. We aimed to evaluate and compare the immediate efficacy of modern energy sealing devices in an ex vivo PA sealing model. ⋯ In this pilot study to examine energy sealing of PA branches in a simulated ex vivo model, vascular sealing using energy was effective and was able to sustain high intraluminal bursting pressures. Further research is needed to determine the in vivo and long-term safety of PA branch energy sealing.
