Multicenter StudyRadiation dose benchmarks during cardiac catheterization for congenital heart disease in the United States.
The aim of this study was to define age-stratified, procedure-specific benchmark radiation dose levels during interventional catheterization for congenital heart disease. ⋯ This study presents age-stratified radiation dose values for 6 common congenital heart interventional catheterization procedures. Fluoroscopy time alone is not an adequate measure for monitoring radiation exposure. These values will be used as baseline for measuring the effectiveness of future quality improvement activities by the Congenital Cardiac Catheterization Project on Outcomes collaborative.

Multicenter StudyAppropriateness ratings of percutaneous coronary intervention in Japan and its association with the trend of noninvasive testing.
The aim of this study was to evaluate the appropriateness of percutaneous coronary intervention (PCI) in Japan and clarify the association between trends of pre-procedural noninvasive testing and changes in appropriateness ratings. ⋯ In a multicenter, Japanese PCI registry, approximately one-sixth of nonacute PCIs were rated as inappropriate under AUC/2009, increasing to approximately one-third under the revised AUC/2012. This significant gap may reflect a needed shift in appropriateness recognition of methods for noninvasive pre-procedural evaluation of coronary artery disease.

Multicenter StudyClinical impact of aortic regurgitation after transcatheter aortic valve replacement: insights into the degree and acuteness of presentation.
The aim of this study was to determine the impact of the degree of residual aortic regurgitation (AR) and acuteness of presentation of AR after transcatheter aortic valve replacement (TAVR) on outcomes. ⋯ AR occurred very frequently after TAVR, but an increased risk of mortality at ∼2-year follow-up was observed only in patients with acute moderate to severe AR.

Multicenter StudyImpact of balloon post-dilation on clinical outcomes after transcatheter aortic valve replacement with the self-expanding CoreValve prosthesis.
The aim of this study was to assess the incidence and clinical impact of balloon post-dilation (BPD) after transcatheter aortic valve replacement (TAVR) with the CoreValve prosthesis (Medtronic Inc., Minneapolis, Minnesota). ⋯ This large study showed that BPD after TAVR was safe and not associated with increased rates of cerebrovascular events, mortality, myocardial infarction, and aortic root injury.
