Preoperative Inspiratory Muscle Training (IMT) with the Powerbreathe device was assessed with regard to whether A-a gradients and inspiratory muscle power would be improved after CABG. A group of 40 male patients were randomized to receiving (20) or not receiving (20) preop IMT.

Effect of Preoperative Inspiratory Muscle Training on Alveolar-Arterial Oxygen Gradients After Coronary Artery Bypass Surgery

In this excellent review article, the authors review the practice and evidence for fractional flow reserve (FFR) in patients undergoing CABG.
Variable selection methods for multiple regressions influence the parsimony of risk prediction models for cardiac surgery
May 22, 2017
A surprisingly readable Australasian manuscript on risk prediction models for cardiac surgery. Interesting that the class of dyspnoea was not captured in 5.28% of the operated patients.

I was moved by this editorial on global health matters in a daily British newspaper by an academic medical colleague, written in response to anticipated changes in the leadership of the World Health Organisation. It is perhaps time for us surgeons to augment our administrative participation in global healthcare.

An international group of experts met at the 2017 STS Annual Meeting in Houston, Texas, to discuss the evolving practice of robotic and hybrid coronary revascularization.

The authors report here on the results of the Italian CHEETAH study, a randomized, double-blind, placebo-controlled trial examining whether adding the unique inotrope levosimendan—in low doses—improves 30-day mortality after cardiac surgery in patients with perioperative LV dysfunction.

The authors demonstrate how to perform a coronary artery bypass with a stented vein graft using a VEST device.

The authors randomized 68 patients undergoing CABG to three treatment groups:
Ten-Year Experience of Coronary Endarterectomy for the Diffusely Diseased Left Anterior Descending Artery
March 5, 2017
The authors describe a 10-year experience with extended arteriotomy for endarterectomy of a diffusely diseased LAD, using an internal mammary artery for reconstruction. Perioperative mortality was 1.1% and postoperative MI occurred in 9%. Survival at 5 years was 89% and freedom from acute cardiovascular events was 74%.
March 5, 2017
This trial randomly assigned 4,752 patients from 19 countries to either on-pump or off-pump CABG with a mean follow-up of 4.8 years. The authors report no difference in death, stroke, myocardial infarction, renal failure or repeat revascularization at 5 years between the two groups.
