Multicenter Study Observational StudyBenefit of Prolonged Dual Antiplatelet Therapy After Implantation of Drug-Eluting Stent for Coronary Bifurcation Lesions: Results From the Coronary Bifurcation Stenting Registry II.
Whether prolonged dual antiplatelet therapy (DAPT) improves clinical outcomes after percutaneous coronary intervention for coronary bifurcation lesion is uncertain. ⋯ URL: https://www.clinicaltrials.gov. Unique identifier: NCT01642992.

Randomized Controlled TrialSubcutaneous Injection of Nitroglycerin at the Radial Artery Puncture Site Reduces the Risk of Early Radial Artery Occlusion After Transradial Coronary Catheterization: A Randomized, Placebo-Controlled Clinical Trial.
Transradial coronary catheterization is widely used as a diagnostic or interventional procedure for coronary disease. However, it can lead to adverse complications, such as radial artery occlusion. We sought to determine whether preprocedural injection of nitroglycerin at the radial artery puncture site reduces radial artery occlusion. ⋯ URL: https://www.chictr.org.cn.

Incidence, Predictors, and Outcomes of Acquired Thrombocytopenia After Percutaneous Coronary Intervention: A Pooled, Patient-Level Analysis of the CHAMPION Trials (Cangrelor Versus Standard Therapy to Achieve Optimal Management of Platelet Inhibition).
The influence of cangrelor on the incidence and outcomes of post-percutaneous coronary intervention (PCI) thrombocytopenia is not defined. We aimed to explore the incidence, predictors, and clinical impact of thrombocytopenia after PCI in cangrelor-treated patients. ⋯ URL: https://www.clinicaltrials.gov. Unique identifiers: NCT00305162, NCT00385138, and NCT01156571.

Observational StudyTranscatheter Versus Surgical Aortic Valve Replacement in Patients With Prior Coronary Artery Bypass Grafting: Trends in Utilization and Propensity-Matched Analysis of In-Hospital Outcomes.
A significant proportion of patients requiring aortic valve replacement (AVR) have undergone prior coronary artery bypass grafting (CABG). Reoperative heart surgery is associated with increased risk. Data on relative utilization and comparative outcomes of transcatheter (TAVR) versus surgical AVR (SAVR) in patients with prior CABG are limited. ⋯ TAVR is being increasingly used as the preferred modality of AVR in patients with prior CABG. Compared with SAVR, TAVR is associated with similar in-hospital mortality but lower rates of in-hospital complications in this important subset of patients.

ReviewThe Case for Selective Patent Foramen Ovale Closure After Cryptogenic Stroke.
Controversy has persisted for over a decade whether transcatheter patent foramen ovale (PFO) closure reduces the rate of recurrent ischemic stroke for patients who have had a cryptogenic ischemic stroke and have a PFO. In September 2017, 3 positive randomized trials: RESPECT long-term (Recurrent Stroke Comparing PFO Closure to Established Current Standard of Care Treatment trial), REDUCE (GORE® HELEX® Septal Occluder / GORE® CARDIOFORM Septal Occluder and Antiplatelet Medical Management for Reduction of Recurrent Stroke or Imaging-Confirmed TIA in Patients With Patent Foramen Ovale [PFO]), and CLOSE (Patent Foramen Ovale Closure or Anticoagulants Versus Antiplatelet Therapy to Prevent Stroke Recurrence) were published. All 3 trials studied young to middle age patients with cryptogenic ischemic strokes found to have a PFO, and compared recurrent stroke rates after PFO closure versus medical therapy alone. ⋯ In the CLOSE trial, device closure plus long-term antiplatelet therapy versus antiplatelet therapy alone demonstrated a risk reduction of 97% (hazard ratio, 0.03; 95% confidence interval, 0-0.25; log-rank P<0.001). Each trial demonstrated a low frequency of device- and procedure-related complications, including a slight increase in the rate of paroxysmal atrial fibrillation in the device arm. This review focuses on summarizing the trial results and translating the results and methods from investigative trials into clinical practice.
