Predicting early left ventricular dysfunction after mitral valve reconstruction: the effect of atrial fibrillation and pulmonary hypertension.
The preoperative ejection fraction (EF) and left ventricular (LV) end-systolic dimension are known predictors of postoperative LV dysfunction after mitral valve repair. We investigated the effect of a preoperative history of atrial fibrillation and moderate pulmonary hypertension (defined as pulmonary artery systolic pressure >50 mm Hg) on early postoperative LV dysfunction. ⋯ In addition to the established predictors of postoperative LV dysfunction, the presence of preoperative pulmonary hypertension and a history of atrial fibrillation in patients undergoing mitral valve repair surgery increased the risk of early postoperative LV dysfunction by almost twofold.

Resource use trends in extracorporeal membrane oxygenation in adults: an analysis of the Nationwide Inpatient Sample 1998-2009.
The study objective was to determine whether significant trends over time have occurred in resource use associated with the use of extracorporeal membrane oxygenation in critically ill adults. ⋯ These results suggest that dramatic increases in resource use associated with extracorporeal membrane oxygenation are not solely the result of increased volume, but in part are due to a shift toward extracorporeal membrane oxygenation use in patient groups (other than in the post-cardiotomy setting) with greater resource use and worse outcomes.

Total arch repair with open triple-branched stent graft placement for acute type A aortic dissection: experience with 122 patients.
To summarize the clinical experiences and midterm follow-up results of total arch repair with open triple-branched stent graft placement for acute type A aortic dissection. ⋯ Total arch repair with open triple-branched stent graft placement is an effective technique with satisfactory early and midterm results. This technique could be an attractive alternative to conventional total arch replacement.

Observational StudyPulmonary fibrosis on multidetector computed tomography and mortality in patients with radiation-associated cardiac disease undergoing cardiac surgery.
In the long-term, malignancy-associated thoracic radiation leads to varying degrees of pulmonary fibrosis and radiation-associated cardiac disease, often requiring cardiothoracic surgery. We sought to determine whether pulmonary fibrosis affects mortality in patients with radiation-associated cardiac disease undergoing cardiothoracic surgery. ⋯ In patients with radiation-associated cardiac disease undergoing cardiothoracic surgery, worsening pulmonary fibrosis is associated with increased mortality.

Smoking cessation before coronary artery bypass grafting improves operative outcomes.
The detrimental effect of active smoking on operative outcome after coronary artery bypass grafting (CABG) is still debated and smoking cessation programs are usually deferred until after surgery. The potential benefit from smoking cessation on postoperative outcomes is investigated in this study. ⋯ This study showed that smoking cessation before CABG reduced the risk of serious pulmonary complications. The present findings indicate that embarking on a smoking cessation program should not be deferred until after surgery.
