Predictors of moderate-to-severe paravalvular aortic regurgitation immediately after CoreValve implantation and the impact of postdilatation.
To investigate the predictors of moderate-to-severe aortic regurgitation (AR≥2+) after CoreValve implantation and evaluate the feasibility and safety of postdilatation in reducing the degree of AR. ⋯ The appropriate strategy for treating patients with AR≥2+ depends on the causes and severity of AR post-TAVI. This study suggests that we should carefully select the size of CoreValve prosthesis to prevent prosthesis mismatch, especially when implanted in larger annulus sizes. For valves implanted in the appropriate position, postdilatation appears effective in reducing the degree of AR.

In-hospital complications after transcatheter aortic valve implantation revisited according to the Valve Academic Research Consortium definitions.
To determine the occurrence of in-hospital complications after transcatheter aortic valve implantation (TAVI) according to the Valve Academic Research Consortium (VARC) criteria in addition to the length of stay (LOS). ⋯ TAVI was associated with ≥1 cardiovascular and/or noncardiovascular event in 51% of the patients; new PPI was needed in another 8%, and TAVI was truly uncomplicated in 41%. Complications and need for new PPI significantly prolonged LOS.

A novel technique for stenting pulmonary artery and conduit bifurcation stenosis.
Distal conduit obstruction is a recognized complication after surgery for congenital heart disease requiring implantation of a conduit from the right ventricle to the pulmonary arteries. Endovascular stenting of distal conduit obstruction can be challenging due to the proximity to the pulmonary artery bifurcation. ⋯ This novel technique appears to be safe and effective for stenting stenoses just proximal to pulmonary artery bifurcation.
