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.

Case ReportsLASER endovascular atherectomy with secondary stenting of technically challenging calcified celiac trunk stenosis.
Endovascular therapy for chronic mesenteric ischemia is a proven, feasible alternative approach to open surgical repair with significantly lower morbidity and mortality. A clinical dilemma is encountered when technically challenging lesions are encountered during the procedure. We present here an 86 year-old woman who had intractable abdominal pain with postprandial exacerbation. The patient had successful endovascular light amplification by stimulated emission of radiation atherectomy of a highly calcified celiac truck, showing the feasibility of this technique.

Interventional cardiology fellowship training in Canada: a report card using standardized criteria.
Several institutions in Canada offer fellowship training in interventional cardiology (IC). However, no national mechanism exists to ensure uniformity of training or assessment of final competency. ⋯ Canadian IC training meets ACGME/ACC recommendations for procedural volume and academic activity. However, participation in outpatient clinics and compliance with administrative requirement of faculty and program assessment by trainee was suboptimal. Formal accreditation is highly desirable to standardize program content and administration for optimal IC training.
