Background— Transcatheter aortic valve implantation is an alternative to open heart surgery
in patients with aortic stenosis. However, long-term data on a programmatic approach to …

Background— The majority of prosthetic heart valves currently implanted are tissue valves
that can be expected to degenerate with time and eventually fail. Repeat cardiac surgery to …

Transcatheter aortic valve implantation (TAVI) is becoming a reality in the management of
patients with severe aortic stenosis and high or prohibitive risk for standard surgical …

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 …

Objectives : This study was undertaken to compare the hemodynamic performance of a
percutaneous bioprosthesis to that of surgically implanted (stented and stentless) bioprostheses …

The RNA-guided CRISPR-associated protein Cas9 is used for genome editing, transcriptional
modulation, and live-cell imaging. Cas9-guide RNA complexes recognize and cleave …

Deviations from Brownian motion leading to anomalous diffusion are found in transport
dynamics from quantum physics to life sciences. The characterization of anomalous diffusion …

Aims We sought to evaluate the outcomes of transcatheter mitral valve replacement (TMVR)
for patients with degenerated bioprostheses [valve-in-valve (ViV)], failed annuloplasty rings […

Background— Patients with severe aortic stenosis and reduced left ventricular ejection
fraction (LVEF) have a poor prognosis with conservative therapy but a high operative mortality …

Objectives : The aim of this study was to compare aspirin plus clopidogrel with aspirin alone
as antithrombotic treatment following transcatheter aortic valve replacement (TAVR) for the …
