Abstract

  • Trusted authorities deliver the key cardiac anesthesia knowledge you need to know.
  • A concise, user-friendly format and key points boxes in each chapter help you quickly locate crucial information.
  • Annotated references guide you to the most practical additional resources.
  • A portable size and clinical emphasis facilitates and enhances bedside patient care.
  • Designed as a companion to Kaplan’s Cardiac Anesthesia.
  • Includes new topics vital to the current practice of cardiac anesthesiologists, such as transesophageal echocardiography; percutaneous valve procedures; new pacemakers and automatic internal defibrillators used for cardiac resynchronization therapy; left ventricular assist devices and extracorporeal membrane oxygenation therapy of heart failure; and patient safety issues.
  • Focuses on today’s most current and relevant therapies, including New Cardiac Drugs, and Heart Mate, Heart Ware, and Impella LVADs.
  • Describes care of the cardiac patient in Hybrid Operating Rooms, Catheterization Laboratories, and Electrophysiology Laboratories, as well as the Cardiac Operating Rooms.
  • Perfectly suited for residents, fellows, nurse anesthetists and anesthesiologists in practice.
