Acute kidney injury following transcatheter aortic valve implantation: predictive factors, prognostic value, and comparison with surgical aortic valve replacement
Aims Very few data exist on the occurrence of acute kidney injury (AKI) associated with transcatheter aortic valve implantation (TAVI). The objectives of the present study were (i) to determine the… Expand

The complex nature of discordant severe calcified aortic valve disease grading: new insights from combined Doppler echocardiographic and computed tomographic study.
OBJECTIVES With concomitant Doppler echocardiography and multidetector computed tomography (MDCT) measuring aortic valve calcification (AVC) load, this study aimed at defining: 1) independent… Expand

Comparison of the hemodynamic performance of percutaneous and surgical bioprostheses for the treatment of severe aortic stenosis.
OBJECTIVES This study was undertaken to compare the hemodynamic performance of a percutaneous bioprosthesis to that of surgically implanted (stented and stentless) bioprostheses for the treatment of… Expand

Impact of low flow on the outcome of high-risk patients undergoing transcatheter aortic valve replacement.
OBJECTIVES This study sought to assess the impact of baseline left ventricular (LV) outflow, LV ejection fraction (LVEF), and transvalvular gradient on outcomes following transcatheter aortic valve… Expand

Feasibility and initial results of percutaneous aortic valve implantation including selection of the transfemoral or transapical approach in patients with severe aortic stenosis.
The purpose of this study was to evaluate the feasibility and initial results of a multidisciplinary percutaneous aortic valve implantation (PAVI) program including the transfemoral approach (TFA)… Expand

B-type natriuretic peptide clinical activation in aortic stenosis: impact on long-term survival.
OBJECTIVES This study was conducted to define the association between serum B-type natriuretic peptide (BNP) activation and survival after the diagnosis of aortic stenosis (AS). BACKGROUND In AS,… Expand

Aortic valve area calculation in aortic stenosis by CT and Doppler echocardiography.
OBJECTIVES The aim of this study was to verify the hypothesis that multidetector computed tomography (MDCT) is superior to echocardiography for measuring the left ventricular outflow tract (LVOT) and… Expand

Outcome of patients with aortic stenosis, small valve area, and low-flow, low-gradient despite preserved left ventricular ejection fraction.
OBJECTIVES The aim of this case match study was to compare the outcome of patients with paradoxical low-flow (left ventricular ejection fraction [LVEF] ≥50% but stroke volume index <35 ml/m(2)),… Expand

Impact of aortic valve calcification, as measured by MDCT, on survival in patients with aortic stenosis: results of an international registry study.
BACKGROUND Aortic valve calcification (AVC) load measures lesion severity in aortic stenosis (AS) and is useful for diagnostic purposes. Whether AVC predicts survival after diagnosis, independent of… Expand
