RE: Halwani DO, et al, In-vivo corrosion and local release of metallic ions from vascular stents into surrounding tissue. J Invasive Cardiol 2010;22:528–535. Dear Editor, In the article by Halwani et al, the interesting finding of transfer of heav…
ABSTRACT: The retrograde approach has been shown to improve the success rate of percutaneous coronary intervention for coronary chronic total occlusion (CTO) when performed by highly experienced operators. We report a very challenging case of a retro…
ABSTRACT: Although extended late-phase in-stent restenosis has been reported even after implantation of bare-metal stents (BMS), the data resolving the mechanism are sparse. We could obtain intravascular ultrasound, optical coherence tomography (OCT)…
ABSTRACT: Implanting new leads for defibrillation or pacing leads could be problematic as a result of venous obstruction. Up to 50% of patients with pacemaker/implantable cardioverter defibrillator leads have an asymptomatic subclavian vein obstructi…
ABSTRACT: Though frequently reported following surgical procedures, urinary retention after cardiac catheterization is rare and has not previously been documented in the literature. We reported 4 cases of acute retention over a 1-year period encounte…
ABSTRACT: Takotsubo cardiomyopathy is a transient acute left ventricular dysfunction characterized by left ventricular apical akinesis and ballooning without obstructive coronary disease described predominantly in post-menopausal women in the setting…
ABSTRACT: A 1.5-year-old child underwent transcatheter closure of patent ductus arteriosus (PDA) and balloon aortic valvuloplasty concurrently with excellent immediate and follow-up results. Technical details of concurrent treatment of both PDA and a…
ABSTRACT: With the advent of modern thin-strut coronary stents, there is potential for damage to the stent structure during delivery. Fraying of the stent during unsuccessful attempts at lesion passage can be particularly problematic as re-entry into…
ABSTRACT: Coronary atherosclerotic aneurysms (CAA) are a very uncommon finding in patients presenting with coronary artery disease. In order to prevent spontaneous vessel rupture in patients presenting with large CAA, these patients are frequently t…
ABSTRACT: We describe the case of a 60-year-old female who presented with a non-ST elevation myocardial infarction 3 months following placement of a non-pulsatile left ventricular assist device (LVAD). Aortic root angiography not only revealed extens…
