¡¡¡¡Ihis 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 fluo-roscopy or contrast agents and so avoid radiation damage and the risks of allergy or renal function impairment. Further£¬ these proce-dures could help to save patients in areas lacking medical resources.The book first demonstrates the substitution of transesophageal for transthoracic echocardiography to avoid intubation under general anesthesia£¬ and then presents key technical and practical aspects of echoguided percutaneous interventions for structural heart diseases£¬such as ASD£¬ VSD£¬ PDA£¬ PS£¬ MS£¬ AS and CoA. Lastly£¬ it explores the lessons learned in echocardiography£¬ anesthesia and postprocedural management of echoguided percutaneous interventions.
