Comparative StudyPrevious coronary stents do not increase early and long-term adverse outcomes in patients undergoing off-pump coronary artery bypass grafting: a propensity-matched comparison.
The aim of our study was to compare the early and long-term outcomes of patients undergoing off-pump coronary artery bypass grafting (CABG) with and without previous coronary stents. ⋯ Previous coronary stents do not increase early and long-term morbidity or mortality in patients undergoing off-pump CABG.

Multicenter StudyChronic competitive flow from a patent arterial or venous graft to the circumflex system does not impair the long-term patency of internal thoracic artery to left anterior descending grafts in patients with isolated predivisional left main disease: long-term angiographic results of 2 different revascularization strategies.
To compare 2 different surgical approaches to treatment of patients with isolated predivisional stenosis of the left main coronary artery (IOSLM) and to evaluate the effect of chronic competitive flow from a patent arterial or venous graft to the circumflex system on the long-term patency of internal thoracic artery (ITA) to left anterior descending grafts. ⋯ In patients with IOSLM, long-term ITA to left anterior descending artery patency is not jeopardized by chronic flow competition from a concomitant arterial or venous graft to the circumflex system. Notably, the addition of a second ITA graft or of a SV to the first ITA does not lead to differences in long-term angiographic patency. Our results minimize the role of flow competition in this setting and should be kept in mind when choosing the appropriate graft configuration.

Comparative StudyEarly and midterm outcomes of hemiarch replacement combined with stented elephant trunk in the management of acute DeBakey type I aortic dissection: comparison with total arch replacement.
For patients with acute DeBakey type I aortic dissection without an intimal tear in the arch, the early and midterm outcomes of hemiarch replacement with stented elephant trunk were compared with those of total arch replacement. ⋯ For patients with acute DeBakey type I dissection without an intimal tear in the arch, hemiarch replacement with stented elephant trunk implantation was easily performed, with satisfactory early and midterm outcomes. For these selective patients, total arch replacement with the stented elephant trunk technique did not improve the late surgical results further.

Analysis of Clostridium difficile infections after cardiac surgery: epidemiologic and economic implications from national data.
Clostridium difficile infections (CDIs) have increased during the past 2 decades, especially among cardiac surgical patients, who share many of the comorbidity risk factors for CDI. Our objectives were to use a large national database to identify the regional-, hospital-, patient-, and procedure-level risk factors for CDI; and determine mortality, resource usage, and cost of CDIs in cardiac surgery. ⋯ Our results have shown that CDI is associated with increased morbidity and resource usage. Additional work is needed to better understand the complex interplay among regional-, hospital-, and patient-level factors.

AusSCORE II in predicting 30-day mortality after isolated coronary artery bypass grafting in Australia and New Zealand.
To update the Australian System for Cardiac Operative Risk Evaluation (AusSCORE) model for operative estimation of 30-day mortality risk after isolated coronary artery bypass grafting in the Australian population. ⋯ The AusSCORE II model provides improved prediction of 30-day mortality and successfully stratifies patient risk. The model will be useful to improve the preoperative consultation regarding risk stratification in terms of 30-day mortality.
