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 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.

The aim of this study was to evaluate the feasibility of two free-breathing late gadolinium-enhanced cardiovascular magnetic resonance (LGE-CMR) techniques (two-dimensional segmented navigator-gated [NAV-LGE] and single-shot [SS-LGE]) by comparing with breath-hold LGE-CMR (BH-LGE) as reference. ⋯ Although both NAV- and SS-LGE improve the image quality in patients with insufficient BH capability, NAV-LGE is superior to SS-LGE in infarct detection and infarct size measurement. NAV-LGE can be a possible first-line technique for patients with inability to perform sufficient BH.
