A comprehensive survey of nonsurgical treatment for a variety of heart diseases that affect the cardiac valves, the heart muscle, and the structure of the heart. The authors describe who these procedures are useful for, how to do them, and how well they work. Major topics of discussion include percutaneous techniques for valvular heart disease, septal defects at both the atrial and ventricular levels, adjunctive therapies during coronary interventions, and angioplasty to treat extracardiac vascular disease, as well as reviews of the cutting-edge imaging modalities now being used in interventional procedures. An accompanying CD-ROM contains video demonstrations of catheterization and and the imaging portions of these procedures.
