This book provides an extensive discussion of echocardiography-guided percutaneous interventional techniques for clinical practitioners, including cardiologists, interventional physicians, surgeons and specialist training candidates. It allows readers to gain a thorough understanding of interpreting echocardiography-guided procedures, which not only protect patients from pain and other complications associated with conventional surgery, but also obviate the use of fluoroscopy or contrast agents and so avoid radiation damage and the risks of allergy or renal function impairment. Further, these procedures could help to save patients in areas lacking medical resources.
