Comparative Study
The Joint Council on Thoracic Surgery Education coronary artery assessment tool has high interrater reliability.
Barriers to incorporation of simulation in cardiothoracic surgery training include lack of standardized, validated objective assessment tools. Our aim was to measure interrater reliability and internal consistency reliability of a coronary anastomosis assessment tool created by the Joint Council on Thoracic Surgery Education. ⋯ Even without instruction on the assessment tool, experienced surgeons achieved high interrater reliability. Future resident training and evaluation may benefit from utilization of this tool for formative feedback in the simulated and operative environments. However, summative assessment in the operative setting will require further standardization and anchoring.

Routine intraoperative frozen section analysis of bronchial margins is of limited utility in lung cancer resection.
Residual disease at the bronchial margin after resection of non-small cell lung cancer (NSCLC) adversely affects survival. To ensure an R0 resection, thoracic surgeons commonly use intraoperative frozen section analysis of the bronchial margin. We hypothesize that frozen section of the bronchial margin is rarely positive and seldom changes intraoperative management. ⋯ Frozen section analysis of the bronchial margin rarely yields a positive result and infrequently changes intraoperative management in patients undergoing NSCLC resection. These data support selective use of intraoperative frozen section of bronchial margins during lobectomy for NSCLC.

Comparison of cardiothoracic training curricula: integrated six-year versus traditional programs.
Traditionally, cardiothoracic residency programs are 2 or 3 years in length and require the completion of a general surgery residency. Six-year integrated programs (IP) that directly match fourth-year medical students have been recently developed. Our objective was to examine the curricula of traditional 2-year (T2) and 3-year (T3) programs and compare them to the curricula of IP. ⋯ Integrated programs should not be considered "cardiac pathways" as they spend a significant amount of time on thoracic rotations. Additional nonsurgical rotations provide an opportunity for residents in IP to develop unique skills not currently provided in traditional programs.

Management of unbalanced common atrioventricular canal (UCAVC) defect by a single-ventricle (SV) approach frequently results in poor outcomes, especially in trisomy 21 patients. In this report we describe our results with conversion to biventricular circulation in UCAVC patients with SV palliation. ⋯ Biventricular conversion from failing SV palliation in UCAVC can be accomplished with an acceptable early and late morbidity and mortality, although need for reintervention was not uncommon.

Case Reports
Reoperative transapical aortic valve implantation for early structural valve deterioration of a SAPIEN XT valve.
We report on the first repeat transapical aortic "valve-in-valve" implantation for severe aortic stenosis in a degenerated transcatheter valve (Edwards SAPIEN XT; Edwards Lifesciences, Irvine, CA) using a second Edwards SAPIEN XT valve.
