Total artificial heart implantation: clinical indications, expected postoperative imaging findings, and recognition of complications.

Objective: The purposes of this article are to review the treatment options for late-stage biventricular heart failure, discuss the clinical indications for total artificial heart (TAH) implantation, illustrate the expected imaging findings after uncomplicated TAH implantation, and highlight the radiologic findings of common and uncommon complications associated with TAH implantation through case examples.

Conclusion: TAH implantation is an effective therapeutic option for the treatment of patients with end-stage biventricular heart failure. The duration of implantation varies depending on a particular patient's medical condition and the eventual availability of a human heart for orthotopic transplantation. TAH recipients often undergo imaging with conventional radiography, CT, or both for the assessment of device-related issues, many of which are life-threatening and require emergency management. As the clinical use of the TAH increases and becomes more commonplace, it is imperative that radiologists interpreting imaging studies recognize both the expected and the unexpected imaging findings that affect patient care.
