Multicenter Study Comparative Study Controlled Clinical Trial Observational Study
Transcatheter aortic valve implantation versus surgical aortic valve replacement for severe aortic stenosis: results from an intermediate risk propensity-matched population of the Italian OBSERVANT study.
Few studies have yielded information on comparative effectiveness of transcatheter aortic valve implantation (TAVI) versus surgical aortic valve replacement (SAVR) procedures in a real-world setting. The aim of this analysis is to describe procedural and post-procedural outcomes in a TAVI/SAVR intermediate risk propensity-matched population. ⋯ Patients undergoing transcatheter and surgical treatment of severe aortic stenosis are still extremely distinct populations. In the relatively low-risk propensity-matched population analyzed, despite similar procedural and 30-day mortality, SAVR was associated with a higher risk for blood transfusion, whereas TAVI showed a significantly increased rate of vascular damage, permanent AV block and residual aortic valve regurgitation.

Randomized Controlled Trial
20-Hour preprocedural hydration is not superior to 5-hour preprocedural hydration in the prevention of contrast-induced increases in serum creatinine and cystatin C.
Although intravenous hydration with isotonic saline is the standard therapy for the prevention of contrast-induced nephropathy (CIN), there is still insufficient evidence concerning the optimal timing to initiate preprocedural intravenous hydration with isotonic saline. ⋯ 20 h-HS is not superior to 5h-HS in the prevention of the contrast-induced increases in serum creatinine and cystatin C in patients with renal insufficiency undergoing an elective coronary procedure.

To investigate the validity and reliability of the EuroQol-5D (EQ-5D), the 12-item Short-Form Health Survey (SF-12v2), and the Hospital Anxiety and Depression Scale (HADS) in a stable coronary population. ⋯ The EQ-5D as well as the SF-12v2 and the HADS are reliable and valid instruments for use in a stable coronary population, both on aggregate European level and on country-specific level. However, our results must be generalized with caution, because EUROASPIRE III patients might not be representative for all patients with stable coronary heart disease.

About a fourth of acute decompensated heart failure (ADHF) patients develop renal dysfunction during their admission. To date, the association of ADHF treatment with the development of worsening renal function (WRF) remains contentious. Thus, we examined the association of WRF with changes in BNP levels and with mortality. ⋯ During ADHF treatment, ΔBNP was not associated with changes in renal function. Development of WRF during ADHF treatment was not associated with mortality. Our study suggests that development of WRF should not preclude diuresis in ADHF patients in the absence of volume depletion.
