Aim: We sought to assess the long term efficacy of the novel VESTAsync™ Eluting Stent (VES) combining a Cro-Co platform with a nanothin-microporous hydroxyapatite surface coating impregnated with a polymer-free low-dose of Sirolimus (55 μg).
Objectives: Drug-eluting stents (DES) constitute a major achievement in preventing re-stenosis, concerns remain regarding the increased inflammatory responses associated with the polymers used. This analysis focuses on outcomes in patients receiving the polymer-free sirolimus-eluting stent system YUKON-Choice (Yukon-DES, Translumina, Germany).
Objectives: To assess feasibility and outcomes of left atrial appendage (LAA) closure when using a patent foramen ovale (PFO) for left atrial access. Background: Because of the fear of entering the left atrium too high, using a PFO for left atrial access during LAA occlusion (LAAO) is generally discouraged. We report our single-center experience using a concomitant PFO for LAAO, thereby avoiding transseptal puncture.
Objectives: To evaluate the clinical efficacy and safety of transcatheter closure (TCC) in patients with ruptured sinus of Valsalva aneurysm (RSVA).
We report an infant with aortic valve atresia, interrupted aortic arch, ventricular septal defect, confluent pulmonary arteries, bilateral arterial ducts, absent common carotid arteries, and anomalous coronary arteries arising from main pulmonary artery. Hybrid procedure consisting of bilateral pulmonary artery banding and bilateral arterial duct stenting was performed at 4 weeks of age. Hybrid procedure can be an alternative palliative approach in an infant with this complex cardiac anatomy. © 2014 Wiley Periodicals, Inc.
Introduction: Balloon expandable transcatheter pulmonary valve systems are not applicable to the large majority of patients with chronic severe pulmonary regurgitation (PR) following surgical right ventricular outflow tract (RVOT) rehabilitation. This report describes the clinical use and short-term follow-up of a novel transcatheter self-expanding pulmonary valve system (Venus P Valve) for rehabilitation of the RVOT in patients with chronic severe PR.
Background: Long-term follow-up after stent dilation of native and acquired pulmonary artery stenosis is scarce in the pediatric population. Most cohorts include a myriad of anatomies and associated conditions.
Objective: The aim of this first-in-man trial was to evaluate vessel response of two doses of the balloon expandable Cobra-P drug-eluting coronary stent (DES).
Objective: Scoring balloons are particularly useful in the acute treatment of fibro-calcific, bifurcation and in-stent restenosis lesions but have not been shown to affect the restenosis rate. Conventional balloons coated with paclitaxel have recently been shown to reduce restenosis rates in certain lesion subsets, but are associated with suboptimal acute results. A novel paclitaxel-coated scoring balloon was developed to overcome these limitations.
Background: We sought to determine the utility of a magnetic navigation system (MNS) in treating a variety of coronary artery lesions including those that could not be revascularized with standard percutaneous coronary intervention (PCI). MNS may add value in the treatment of tortuous arteries and bifurcation lesions; however its widespread adoption has lagged because of cost and a lack of clear advantage over conventional PCI. We performed a retrospective analysis to determine whether MNS improved procedural success for highly complex lesions.
Background: Aortocoronary dissection can complicate percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs).
Objective: To compare optical coherence tomography (OCT)-derived plaque characteristics of coronary target lesions between diabetic patients with acute coronary syndrome (ACS) versus stable angina pectoris (SAP).
Objectives: To compare intracoronary near-infrared spectroscopy (NIRS) and optical coherence tomography (OCT) for the detection of lipid, to identify NIRS signals to differentiate superficial lipid, and to characterize the plaque with yellow block (YB) chemograms on NIRS.
Objectives: To compare strut coverage patterns between everolimus-eluting stent (EES) and first-generation drug-eluting stents (DES) at more than 12 months after successful implantation, using optical coherence tomography (OCT).
Background: Optical coherence tomography (OCT) coronary imaging requires displacement of red blood cells from the vessel lumen. This is usually accomplished using radiographic contrast. Low molecular weight dextran has low cost and is safe in low volumes. In the present study, we compared dextran with contrast for coronary OCT imaging.
