In patients referred for aortic valve replacement (AVR) a pre-surgical assessment of coronary artery disease is mandatory to determine the possible need for additional coronary artery bypass grafting. The diagnostic accuracy of coronary computed tomography angiography (coronary CTA) was evaluated in patients with aortic valve stenosis referred for surgical AVR. ⋯ In patients with aortic valve stenosis referred for surgical AVR the diagnostic accuracy of coronary CTA to identify significant coronary artery disease is moderate. Coronary CTA may be used successfully in a subset of patients with low age, no chronic obstructive lung disease, NYHA function class

The aim of the study is to design a specific Intensive Care Unit length-of-stay risk model based on the preoperative factors and surgeries utilizing modeling strategies for time-to-event data in a prospective observational clinical study. ⋯ ICU-LOS can be predicted by preoperative data and type of surgeries. The derived ICU-LOS prediction model is dynamic and most predictors have an effect that decreases with time. The algorithm can preoperatively predict ICU-LOS curves and could have a major role in the decision making-behavior of clinicians, resources' allocation and maximization of care for high-risk patients.

The risk of stroke associated with atrial fibrillation (AF) is higher in Far Eastern population than in Western population, and warfarin use suboptimal. There is uncertainty whether the novel oral anticoagulants (NOACs) would have a major impact on stroke prevention in Far Eastern populations with AF. ⋯ There was suboptimal stroke prevention with no difference between antiplatelet and OAC treated patients, perhaps reflecting an inappropriate Target INR range. On modeling analyses, the use of the NOACs (apixaban and dabigatran) could provide better stroke prevention compared to antiplatelet (or warfarin) use in this Chinese AF population, with a positive net clinical benefit.

Observational Study
Incidence, predictors and prognostic value of serious hemorrhagic complications following transcatheter aortic valve implantation.
TAVI is an alternative solution for patients with aortic valve stenosis (AS) who are refused for conventional surgery. We sought to evaluate the incidence, characteristics, predictors and prognosis impact of serious hemorrhagic complications following transcatheter aortic valve implantation (TAVI). ⋯ Severe bleeding is frequent following TAVI procedure and is mainly related to local hemorrhage. VARC LT/D events are associated with decreased survival after AS correction.

We determined whether pre-operative statin therapy is associated with a decrease in the incidence of infections after coronary artery bypass grafting (CABG). ⋯ Pre-operative statin use is associated with a decrease in overall incidence of post-operative infections after CABG. We propose immunomodulatory effects of statins leading to a dampening of inflammatory cascade as the cause of our findings.
