Comparative StudyPrediction of postoperative atrial fibrillation in a large coronary artery bypass grafting cohort.
The objective of this study was to identify and evaluate predictors of postoperative atrial fibrillation (POAF) in a large coronary artery bypass grafting (CABG) cohort. This was a single centre study of 7115 consecutive patients with preoperative sinus rhythm who underwent isolated CABG between January 1996 and December 2009. Independent risk factors for POAF were identified with multiple logistic regression. ⋯ The final prediction model was moderate (area under curve, 0.62; 95% confidence interval, 0.61-0.64). Patients with POAF had more postoperative complications, including a higher incidence of stroke and increased length of hospital stay. In conclusion, several risk factors for POAF were identified, but the moderate value of the prediction model confirms the difficulty of identifying patients at high risk of developing POAF after CABG.

Surgical treatment for retrograde type A aortic dissection after endovascular stent graft placement for type B dissection.
Retrograde type A aortic dissection (RTAD) is a life-threatening and underestimated complication of endovascular stent graft placement for type B dissection. Here, we retrospectively investigated our experience of surgical treatment for RTAD after endovascular stent graft placement for type B dissection. Between June 2006 and September 2011, nine patients with RTAD were transferred to our department for surgery. ⋯ The mean follow-up was 34.79 ± 19.37 months and eight patients are still alive. One patient was lost to follow-up. Surgical treatment for RTAD is a safe alternative and the results are encouraging.

Case ReportsDiscrete subaortic stenosis 37 years after repair of a ventricular septal defect.
Discrete subaortic stenosis (DSS) is uncommon in adults after surgical correction of congenital heart defects. There are only a few published reports on the occurrence of DSS in adults. ⋯ Thirty-seven years later, she presented with congestive heart failure associated with severe subaortic membranous stenosis and atrial fibrillation (AF) that required surgical repair. We report successful surgical treatment of this adult patient with DSS and AF 37 years after repair of a VSD.

Case ReportsIsolated aortic root dilatation following sinotubular junction reduction using prosthetic rings.
'Comprehensive Aortic Root and Valve Reconstruction' technique, which was first introduced in 2005 involves aortic root reduction using prosthetic rings in order to preserve the native aortic sinuses in patients having aortic regurgitation associated with aortic root dilatation. We report a case of isolated aortic sinus aneurysm in a Marfan syndrome patient following the aortic root preserving surgery in the presence of ascending aorta aneurysm and annuloaortic ectasia. Re-operation consisted of aortic sinus resection and replacement with an artificial graft, and coronary reimplantation using a button technique. Close follow-up is essential for patients who underwent aortic root preserving surgery to appropriately manage this kind of complication.

ReviewIs routine stress ulcer prophylaxis of benefit for patients undergoing cardiac surgery?
A best evidence topic in cardiac surgery was written according to a structured protocol. We address whether routine pharmacological stress ulcer prophylaxis is of benefit for patients undergoing cardiac surgery. One hundred and fifty-six papers were found using the reported search, of which 10 represented the best evidence to answer the clinical question. ⋯ Two prospective cohort studies that examined the use of PPI in conjunction with clopidogrel in patients with coronary artery disease concluded that there was no association with an increase in major adverse cardiovascular events with the use of PPIs. We conclude that the current evidence is marginally in favour of the use of prophylactic PPIs. However, this is associated with an increased risk of hospital-acquired pneumonia.
