Development of a patient-centered aggregate score to predict survival after lung resection for non-small cell lung cancer.
The objective of this analysis was to develop a survival aggregate score (SAS), including objective and subjective patient-based parameters, and assess its prognostic role after major anatomic resection for non-small cell lung cancer. ⋯ This system may be used to refine stratification of prognosis for clinical and research purposes.

A shifting approach to management of the thoracic aorta in bicuspid aortic valve.
The scientific understanding of aortic dilation associated with bicuspid aortic valve (BAV) has evolved during the past 2 decades, along with improvements in diagnostic technology and surgical management. We aimed to evaluate secular trends and predictors of thoracic aortic surgery among patients with BAV in the United States. ⋯ There was a marked increase in the use of thoracic aortic surgery among patients with BAV.

Single surgical procedure combining epicardial pacemaker implantation and subsequent extraction of the infected pacing system for pacemaker-dependent patients.
Management of pacemaker infection in pacing-dependent patients is often challenging. Typically, temporary pacing is used while antibiotic therapy is given for a number of days before reimplantation of a new endocardial system. This results in a prolonged hospital stay and complications associated with temporary pacing. In this study, we examine the feasibility of performing a single combined procedure of epicardial pacemaker implantation followed by system extraction. ⋯ A single combined procedure of surgical epicardial pacemaker implantation and pacemaker system extraction appears to be a safe and effective method for managing pacemaker-dependent patients with infected pacemakers.

Influence of left ventricular function on development of systolic anterior motion after mitral valve repair.
A hyperkinetic heart has been suggested as a risk factor for systolic anterior motion (SAM) after mitral valve repair, but the influence of preoperative left ventricular (LV) function on the development of SAM has not been elucidated. ⋯ The study indicates that the development of SAM after mitral valve repair is associated with preoperative LV function. A small hyperkinetic heart is considered a risk factor for SAM and should be treated with caution.

Comparative StudyDurability of left ventricular assist devices: Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) 2006 to 2011.
The present study compared the interval until device exchange or death from pump-related failure in patients with pulsatile versus continuous flow left ventricular assist devices. ⋯ The Analysis of Interagency Registry for Mechanically Assisted Circulatory Support data showed greater durability for continuous flow than for pulsatile left ventricular assist devices. Even longer durations of support can be expected if pump durability continues to improve.
