Transcatheter aortic valve replacement (TAVR) is an alternative and now recommended therapy for patients who meet indications for surgical valve replacement and are high or prohibitive surgical risk. Available TAVR technologies are rapidly emerging to treat this complex patient population. This review discusses the specific valve designs of the transcatheter heart valves currently used, newer generation modifications to overcome limitations of earlier valve designs, and novel imaging modalities, such as computed tomographic angiography-fluoroscopy and echocardiography-fluoroscopy fusion imaging, available for pre-procedural planning and intra-procedural guidance.
