ReviewUse of antiplatelet drugs after cardiac operations.
Unfortunately, venous bypass grafts still have a prominent role in operative coronary revascularization (coronary artery bypass graft [CABG]). Venous grafts develop pathologically occlusive disease that limits the effectiveness of CABG, and antiplatelet drugs following operation may limit this problem. ⋯ Evidence suggests that, in most CABG patients, dual antiplatelet drugs (aspirin and clopidogrel), given after operation, minimizes early (within 1 year) graft failure and improves intermediate-term outcomes, better than single antiplatelet therapy with aspirin alone. There are gaps in the knowledge base that supports this contention, and future clinical trials will likely augment or alter this recommendation.

ReviewThe theory, practice, and future of process improvement in general thoracic surgery.
Process improvement, in its broadest sense, is the analysis of a given set of actions with the aim of elevating quality and reducing costs. The tenets of process improvement have been applied to medicine in increasing frequency for at least the last quarter century including thoracic surgery. This review outlines the theory underlying process improvement, the currently available data sources for process improvement and possible future directions of research.

Technical performance score as predictor for post-discharge reintervention in valve-sparing tetralogy of Fallot repair.
Recognition of late problems following repair of tetralogy of Fallot (TOF) with a transannular patch has stimulated modifications to preserve pulmonary valve (PV) function. This study assesses the ability of technical performance score (TPS) to determine the need for post-discharge reinterventions (RIs) in valve-sparing TOF repair. We retrospectively reviewed 157 patients following valve-sparing repair of TOF from 2007-2012. ⋯ TPS is associated with post-discharge RI rate after valve-sparing TOF repair. Preoperative PV Z score is highly correlated with Class I TPS. Patient selection based on preoperative PV Z scores may help determine if valve-sparing approach is appropriate, thus minimizing the need for RIs.

The new IASLC-ATS-ERS lung adenocarcinoma classification: what the surgeon should know.
In 2011, a new histologic classification of lung adenocarcinomas was proposed from a joint working group of the International Association for the Study of Lung Cancer, American Thoracic Society, and European Respiratory Society, based on the recommendation of an international and multidisciplinary panel. This classification proposed a method of comprehensive histologic subtyping (lepidic, acinar, papillary, micropapillary, and solid pattern) based on semiquantitative assessment of histologic patterns (in 5% increments), with the ultimate goal of choosing a single, predominant pattern. Prognostic subsets could then be described for the classification. ⋯ We also review the published studies that identified the importance of histologic subtypes in predicting recurrence, both rates and patterns, in early-stage lung adenocarcinomas. This new classification for the most common type of lung cancer is useful for surgeons, as its implementation would require only hematoxylin-and-eosin histology slides, which is the common type of stain used in hospitals. It can be implemented with routine pathology evaluation and with no additional costs.
