Since the introduction of laser devices to the medical sciences this techlogy has created great interest. Specifically, the laser's unique physical properties and precise bio-tissue interactions render this versatile source of biologic energy an attractive tool for multiple therapeutic purposes in cardiovascular medicine. Over the course of the last 2 decades the utilization of laser techlogy has become an important component for the management of patients with complex cardiovascular diseases. During this time period, cutting edge laser techlogy including a variety of wave length generators, newly designed catheters, and a selection of advanced optic fibers have been introduced and applied in the cardiovascular circulation. Improved lasing techniques in the cardiac catheterization suites and operation rooms have been implemented for treatment of ischemic coronary syndromes, peripheral arterial occlusive disease and other atherosclerotic thrombotic conditions. Moreover, during this 20 year time frame, several multicenter and single center clinical studies have been published focusing on the role and utilization of lasers in coronary and peripheral revascularization. And within the rapidly expanding field of interventional cardiac electrophysiology, laser techlogy has recently revolutionized the management of fractured, abandoned and malfunctioning leads of cardiac pacemakers and automatic defibrillators. Consequently, replacing a toriously cumbersome and high risk open heart surgery with safe and markedly efficient percutaneous laser based extraction. This textbook will provide the most authoritative, comprehensive and contemporary information covering techlogical progress, clinical experience and pertinent aspects of laser applications in cardiovascular medicine. It will be of interest to cardiologists, vascular surgeons and interventional radiologist as well as medical students, scientists, biomedical engineering students and graduates.
