COMMENTARY: Alternative Safe, Effective and Cost-Efficient Dosing for Eptifibatide in Low-Risk Patients

08/01/2008

Platelets play a central role in coronary atherothrombosis.1 Local trauma to the coronary artery at the site of percutaneous coronary intervention (PCI) causes endothelial denudation and platelet activation. The level of ambient platelet...

Embolic ProtectionDevices in Saphenous Vein Graft Interventions: Is There Still a Role?

01/04/2012

Tarek A. Helmy , MD;

Arumugam Narayanan , MD;

Mouhamad Abdallah , MD;

Saphenous vein grafts (SVG) are commonly used conduits for coronary bypass, with a graft failure rate of up to 45% per patient and 29% per graft on angiographic follow-up at 18 months.1 Atherosclerotic plaques in SVGs tend to be bulky,...
