conclusions music therapy is a safe, simple, inexpensive, and non-invasive nursing intervention, which can significantly alleviate patients’ anxiety during coronary angioplasty. patients and methods this was a randomized controlled trial, conducted in the catheterization laboratory unit of baqiyatallah hospital, in tehran, iran. a sample of 64 patients, who were planned to undergo coronary angi...

Within the last few years, lasers have gained increasing use in the management of cardiovascular disease, and laser angioplasty has become a widely performed procedure. For this reason, a basic knowledge of lasers and their applications is essential to vascular surgeons, cardiologists, and interventional radiologists. To elucidate some fundamental concepts regarding laser physics, we describe h...

Angioplasty of the proximal portions of major cerebral arteries at the base of the brain has shown promise as a therapy for symptomatic vasospasm after subarachnoid hemorrhage. The blind-ended, single-lumen balloon-dilatation catheter most widely used to date lacks steerability, limiting its application to unbranched stems and single branches at bi- or trifurcation points. To extend the capabil...

OBJECTIVE To estimate the cost-effectiveness of primary angioplasty compared with thrombolysis for acute ST elevation myocardial infarction. Design Cost analysis of UK observational database, incorporated into decision analytical model. METHODS Patients receiving treatment within a comprehensive angioplasty service were compared with control patients receiving thrombolysis-based care. The tre...

BACKGROUND The anatomic success of percutaneous angioplasty of venous stenosis is determined by the improvement in cross-sectional diameter of the vessel. A successful outcome is defined as a residual stenosis of <30%. The purpose of this study was to determine whether the angiographic assessment of a venous stenosis correlates with the change in graft blood flow following angioplasty. METHOD...

BACKGROUND AND PURPOSE The use of cocaine has been associated with stroke. To evaluate carotid vasospasm as a potential mechanism of cocaine-induced stroke, we studied 12 swine immediately and 10 weeks after angioplasty. METHODS We compared the short- and long-term vasoconstrictor responses of normal and injured arterial segments to nitroglycerin, histamine, and cocaine in vivo by carotid ang...

OBJECTIVES This study evaluated the acute physiological gain of adjunctive intravascular ultrasound (IVUS) guided balloon angioplasty and stent implantation. BACKGROUND Recent studies indicate safe coronary luminal enlargement and "stent-like" long-term outcomes using upsized balloons guided by IVUS. METHODS After angiographically guided balloon angioplasty in 20 patients with 1-vessel dise...
