Abstract: Saphenous vein grafts are prone to degeneration and occlusion. Vein graft disease continues to be a significant problem in maintaining long-term benefits after coronary artery bypass surgery. The neointimal hyperplasia and aggressive athero…
Abstract: Intravascular fracture of angiographic catheters is very uncommon, but it happens. Removal of an intravascular foreign body may require surgical intervention or non-surgical retrieval necessitating additional vascular access (mostly via fem…
Abstract: Accurate measurement of transvalvular pressure gradients is essential to comprehensively evaluate whether mechanical prosthetic valves are functioning normally. Direct measurements can be technically complicated, traditionally requiring dir…
The recent publication of the Placement of Aortic Transcatheter Valves (PARTNER) trial and subsequent FDA approval of the Edwards Sapien balloon-expandable transcatheter aortic valve replacement (TAVR) system have shed new light on the treatment of a…
Abstract: With the introduction of transcatheter aortic valve implantation (TAVI), the precise role of balloon aortic valvuloplasty (BAV) remains to be established. Methods. Between August 2008 and November 2010, consecutive patients undergoing BAV f…
Abstract: Objectives. The present study evaluated the mechanism of edge restenosis after sirolimus-eluting stent (SES) implantation using serial (post-intervention and follow-up) intravascular ultrasound (IVUS) analysis. Background. There is little i…
Oral dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor, most often clopidogrel, has been demonstrated to reduce the composite risk of ischemic morbidity and mortality across a wide range of patient groups including those with acute…
Abstract: Background. The current standard of care is to delay coronary surgery 5-7 days after clopidogrel exposure to prevent bleeding complications. We sought to determine the utility of an objective tool (ie, the VerifyNow assay) to measure platel…
Abstract: Objectives. The purpose of this study was to assess the effect of remote ischemic precondition (RIPC) on the incidence of myocardial and renal injury in patients undergoing cardiovascular interventions as measured by biomarkers. Clinical da…
Abstract: Background. Crush stenting mandates a final kissing-balloon technique (KBT) for a better clinical outcome; however, recrossing the 2 overlapping stent struts with the balloon catheter is technically challenging. Objectives. The efficacy of…
