Use of a distal protection device is essential in current percutaneous coronary intervention (PCI) procedures because distal embolization can be avoided with some specific lesions such as vein grafts,1,2 carotid stenoses3,4 and thrombus-rich coronary…
Percutaneous closure of atrial septal defects (ASDs) is a safe procedure and has been routinely performed in many centers around the world as an alternative to surgical closure.1–5 However, in elderly patients with ASD, prolonged left-to-right shunt…
Atrial septal defects (ASD), which comprise roughly 10% of all congenital cardiac disease, are frequently first encountered in the adult population.1 Significant shunting results in the insidious development of symptoms, culminating in overt heart fa…
Multiple devices are currently available for closure of the femoral artery access site after cardiac catheterization.1 Currently, the most widely used closure devices are the Angio-Seal™ device (St. Jude Medical, St. Paul, Minnesota)2–4 and the Percl…
The introduction of vascular closure devices (VCDs) in the mid-1990s has truly made a difference for the interventional cardiologist. Despite a multitude of studies showing either decreased, increased or similar rates of vascular complications, VCDs…
Coronary artery aneurysms (CAAs) represent a relatively uncommon finding in patients who undergo percutaneous coronary intervention (PCI). However, the prevalence of CAAs has been shown to be higher in patients undergoing PCI utilizing directional c…
Stent thrombosis (ST) is a recognized complication limiting the clinical efficacy of percutaneous coronary interventions (PCI), the incidence reported being between 0.5% and 2.2%.1–5 Due to the increasing number of stent-based PCI procedures, the abs…
Stent thrombosis (ST), while infrequent, is a serious complication of percutaneous coronary intervention (PCI) resulting in myocardial infarction (MI) or death.1–4 While drug- eluting stents (DES) have reduced the rate of restenosis and target lesion…
B-type natriuretic peptide (BNP) and serum unbound free fatty acid (FFAu) are novel cardiac markers. BNP is a polypeptide secreted by the cardiac ventricles in response to volume and pressure overload. Measurement of BNP levels has demonstrated diagn…
Primary percutaneous coronary intervention (PCI) is established as optimal therapy for patients with ST-elevation myocardial infarction (STEMI).1 The goal of primary PCI is to achieve a thrombolysis in myocardial infarction (TIMI) 3 flow and also to…
