The Role of Preoperative and Intraoperative Imaging in Guiding Transcatheter Aortic Valve Replacement.

Optimal intraprocedural imaging is central to transcatheter aortic valve replacement (TAVR). Familiarity with commonly used modalities is necessary. Real-time, intraprocedural imaging is provided by fluoroscopy and echocardiography to ensure proper valve position and deployment, and to assess for postdeployment complications. By providing anatomic information to real-time fluoroscopy, fusion imaging has the potential to positively affect TAVR. As newer generation valves are introduced and as TAVR is potentially offered to lower risk patient populations, it will be important to ensure that improvements in intraprocedural imaging lead to better outcomes.
