The University of Virginia group retrospectively analyzed all non-emergent cardiac cases performed at their center from 2008 to 2013, and separated the nonemergent cases into two groups: "Early start" cases had an incision time before 3 PM, and "late start" cases, after 3 PM.

The authors analyzed an audited collaborative multicenter database in Australia of over 34,000 consecutive patients who underwent CABG from 2001 to 2012, and they compared outcomes in those undergoing total arterial revascularization (TAR) vs. those that did not.

The authors of this paper investigated the outcomes of percutaneous coronary intervention (PCI) performed in centers with and without cardiac surgical support onsite in a large database in the United Kingdom between 2006 and 2012. They found in multivarate analysis that there was no difference at 30 days, 1 year or 5 years.

The authors conducted a randomized prospective study comparing 3 methods of SVG harvesting in 156 patients. The 3 methods compared were as follows: Conventional (C)--stripped and distended veins; Intermediate (IM)--stripped but not distended veins; and, No Touch (NT)--neither stripped nor distended but harvested on a pedicle.

The University of Pennsylvania group, in a porcine model of ischemic mitral regurgitation (IMR), compared echocardiographic surface coaptation in two groups of pigs: Those undergoing MV repair with a flat semirigid annuloplasty ring vs. with a saddle-shaped rigid annuloplasty ring.

This is a provocative study questioning the current practice of using blood pressure targets perioperatively to ensure adequate perfusion. Plasma levels of a brain-specific injury biomarker (GFAP) were measured in 121 patients undergoing cardiac surgery.

This video shows how to modify the trap-door technique, commonly used in the arterial switch operation in children, in order to re-implant the coronary ostia in adult patients undergoing aortic root replacement.

The authors retrospectively analyzed the STS datablase for utilization of bilateral mammary artery (BIMA) grafts in patients considered at low risk for BIMA use. This group of patients were compared to a propensity matched group of single mammary artery graft (SIMA) patients.

Retrospective cross-sectional cohort study using 5 years of Medicare benficiary data to determine whether post discharge mortality varies by time-to-readmission. Two of the three operations analyzed were lung resection (n=101,092) and coronary artery bypass grafting (CABG) (n=484,260).

Using propensity score matching techniques, outcomes and costs for robotic cardiac surgery were compared to open cardiac surgery using data from the Nationwide Inpatient Sample. Robotic surgery was more expensive ($39,030 vs $36,340) but was associated with a shorter length of stay (5 vs 6 days), lower mortality (1.0% vs 1.9%), and lower overall com
