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.

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.

Randomized Controlled Trial Multicenter StudyPredictors of recurrent events in patients with cryptogenic stroke and patent foramen ovale within the CLOSURE I (Evaluation of the STARFlex Septal Closure System in Patients With a Stroke and/or Transient Ischemic Attack Due to Presumed Paradoxical Embolism Through a Patent Foramen Ovale) trial.
This study sought to identify predictors of recurrent ischemic neurologic events within the CLOSURE I (Evaluation of the STARFlex Septal Closure System in Patients With a Stroke and/or Transient Ischemic Attack Due to Presumed Paradoxical Embolism Through a Patent Foramen Ovale) trial. ⋯ These findings suggest an alternative etiology to paradoxical embolism was frequently responsible for recurrent events within the CLOSURE I trial. (Evaluation of the STARFlex Septal Closure System in Patients With a Stroke or TIA Due to the Possible Passage of a Clot of Unknown Origin Through a Patent Foramen Ovale (PFO) [CLOSURE I]; NCT00201461).

Multicenter Study Comparative StudyComparative outcomes after unprotected left main stem percutaneous coronary intervention: a national linked cohort study of 5,065 acute and elective cases from the BCIS Registry (British Cardiovascular Intervention Society).
The goal of this study was to report outcomes from percutaneous coronary intervention (PCI) to an unprotected left main stem (UPLMS) stenosis according to presenting syndrome, including ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation acute coronary syndrome (NSTEACS), and chronic stable angina (CSA). ⋯ More than one-half of the patients who received UPLMS PCI were acute where outcomes were much worse than elective cases. Cardiogenic shock is common in STEMI patients, of whom more than one-half die at 30 days. The radial approach was associated with reduced early mortality in acute cases.
