Not only an authoritative 16 year retrospective report on 957 planned aortic aneurysm surgeries from Cleveland Clinic, but a stimulating critique ( pages 771-774) with Tyrone David who was the invited discussant of the manuscript at its presentation at the AATS last April. The debate on selective criteria on replacing an aorta with a diameter of 46mm are particularly interesting (page 772).

Early hepatic dysfunction has previously been reported to be an independent risk factor for poor prognosis in critical ill patients. Hepatic and bowel ischemic complication are unfortunately common in patients that require venoarterial (VA) ECMO therapy following a cardiac surgery procedure. It is unclear if biomarkers of liver dysfunction predict outcomes in these patients. Therefore, in this single centre, retrospective study, the Authors sought to determine the predictive value of liver function variables on all-cause mortality in 240 patients requiring venoarterial (VA) ECMO therapy following a cardiac surgery procedure. The Authors have found that elevated values of alkaline phosphatase and total bilirubin were sensitive parameters for predicting the short-term and long-term outcomes in postoperative cardiac patients requiring VA-ECMO. The Authors have concluded that these may represent important biomarkers in the decision-making algorithm in the implementation of ECMO.

The Hopkins group reviewed differential outcomes in close to 800 patients who had undergone bilateral IMA revascularization during CABG. The compared configurations included:
- IS LITA-LAD and IS RITA-left coronary circulation
- IS LITA-LAD and IS RITA-right coronary circulation
- IS RITA-LAD and IS LITA-left coronary circulation
- IS LITA-LAD and Composite RITA to anywhere
Outcomes analysis failed to detect a difference in outcome endpoints consisting of long-term survival or repeat revascularization among the four configurations.
Is this enough evidence to say that it does not matter which of the techniques you use?

This Belgian study prospectively analyzed the predictors of long-term mortality in a group of 107 consecutive CABG patients with an LV EF < 35%. All patients underwent preoperative Cardiac MR to assess both LV and RV EF. Right ventricular systolic dysfunction (RVSD), defined as an RV EF < 35%, was a strong independent predictor of mortality at a median follow-up of 4.7 years. The presence of RVSD more than doubled long-term mortality.

The authors reviewed the Medicare database to analyze the trends in CABG surgery within this population over a 12-year period. Trends in the Medicare population included the following:
- CABG volume decreased by 46%.
- An increasing percentage of CABGs were with fewer grafts (<2).
- ITA use increased from 76% to 89%.
- Comorbidites increased over time.
- The risk-adjusted mortality decreased by 27%.

The authors provide an excellent overview of the rationale for screening all patients with a new diagnosis of cardiomyopathy for coronary artery disease. This rationale includes the following:
- Two-thirds of patients with HF and reduced EF have CAD.
- Patients with CAD may deny angina, especially diabetics and females.
- Even without risk factors, more than 10% of HF patients have CAD.
- The important benefit of revascularization and secondary prevention in patients with CAD.

This is a very interesting and provocative article that discusses Exracorporeal Cardiac Life Support (ECLS) as an adjunct to CPR. ECLS has gained in popularity with new tools and techniques, ECLS guidelines, protocols and better understanding of the importance of early initiation.

The authors report on the transplantation of allogeneic bone graft in 10 patients with massive post-sternotomy defects. There were no further complications in 6 patients. In 3 patients additional re-suture of the soft tissue was necessary and one patient died 6 months later. Allogeneic bone graft transplantation seems to be a promising method in patients with serious tissue loss after sternotomy.

607 consecutive patients with non-small-cell lung cancer who had undergone pulmonary resection were analyzed according to the distance from their home to the hospital: 0 < 10, 10–30 and >30 km. The mean postoperative hospital stay differed between the groups, but there were no significant differences in the median length of follow-up, disease-free survival.

The analysis compares 1478 patients who underwent CABG and received no red blood cell (RBC) transfusion to 1528 CABG patients with 1–2 units of RBCs. The 30-day mortality rate was 0.3% and 0.2%, respectively. The propensity score-adjusted odds ratio (OR) in the RBC+ group was 0.29 [95% confidence interval (CI): 0.06–1.50; P = 0.14]. Major clinical complications did not differ significantly between groups.
