Noninvasive assessment of left ventricular function in chronic heart disease.

abstract：BACKGROUND:As stenting practice has evolved to include greater numbers of stents and adjunctive balloon catheters per case, concern has focused on the increasing costs of equipment for the delivery of stents. METHODS AND RESULTS:To evaluate temporal changes in costs of intracoronary stenting, we examined total costs, ...
