In 2011 there were 658 percutaneous coronary intervention cases performed with more than 60% of the patients presenting to the hospital as an acute coronary syndrome. Most procedures consisted of balloon dilatation followed by stent deployment, and 93% of these stents were drug-eluting stents. Procedural success was achieved in 93.3% of cases and an overall major adverse cardiac events rate of ...
OBJECTIVE A variety of postmarketing surveillance strategies to monitor the safety of medical devices have been supported by the U.S. Food and Drug Administration, but there are few systems to automate surveillance. Our objective was to develop a system to perform real-time monitoring of safety data using a variety of process control techniques. DESIGN The Web-based Data Extraction and Longit...
Coronary angiography through selective injection of radiopaque contrast agent into the coronary arteries is currently the gold standard for evaluating coronary artery disease (CAD). Subjective visual estimation of lesion severity has been shown to be inadequate due to high degrees of intraobserver and interobserver variability (Topol & Nissen, 1995). Since the late 1980s methods and algorithms ...
There have been substantial improvements made in the tools and techniques used since the advent of percutaneous coronary intervention. What was primarily developed as a treatment of coronary artery disease is now used to address a variety of structural heart disease problems. The outcomes have been remarkably successful with relatively low complication rates that rival the results of open-heart...
Development of contrast-induced nephropathy (CIN), ie, a rise in serum creatinine by either ≥0.5 mg/dL or by ≥25% from baseline within the first 2-3 days after contrast administration, is strongly associated with both increased inhospital and late morbidity and mortality after invasive cardiac procedures. The prevention of CIN is critical if long-term outcomes are to be optimized after percutan...
