INTRODUCTION Print Section Listen The limitations inherent to angiography served as a technological springboard for the development of other devices in search of better visualization, quantification, and identification of the…
INTRODUCTION Print Section Listen The technical goal of coronary stenting should be to eliminate or lessen ischemic symptoms in the short/intermediate term and possibly reduce the risk of death or…
HISTORICAL PERSPECTIVE Print Section Listen Computed tomography (CT) was developed in the early 1970s. The first computed axial tomography (CAT) scanners developed by Sir Geoffrey Hounsfield and colleagues required long…
INTRODUCTION Print Section Listen Appropriate selection and manipulation of equipment is critical to successful percutaneous coronary intervention (PCI) outcomes and low complication rates. The guidewire is the first piece of…
HISTORY Print Section Listen The first known attempt at radial artery access for angiography was made in March 1947 by Dr. Stig Radner in Lund, Sweden. He reported on his…
INTRODUCTION Print Section Listen Percutaneous transluminal coronary angioplasty (PTCA) was first described by Andreas Gruentzig in 1976, when he reported the successful application of the new technique in canine coronary…
HISTORICAL PERSPECTIVE Print Section Listen Radiocontrast was first described to cause nephrotoxicity in the 1960s.1,2 Contrast-induced nephropathy (CIN), now termed contrast-induced acute kidney injury (CI-AKI), is likely to increase in…
INTRODUCTION Print Section Listen Although coronary angiography remains the reference standard for diagnosing critical epicardial coronary artery disease (CAD), it has a number of limitations. Identifying functionally significant intermediate coronary…
INTRODUCTION Print Section Listen Adjunctive physiologic and intravascular imaging modalities as described in Chapters 24 and 25 enable operators to 1) direct ischemia-guided revascularization; 2) diagnose microvascular disease, coronary vasospasm,…
INTRODUCTION Print Section Listen Acute coronary artery occlusion is a dynamic process that involves three essential processes: compromise of vascular integrity, platelet activation and aggregation, and acceleration of the coagulation…
