Despite the challenges associated with periprocedural imaging, transcatheter tricuspid valve interventions have shown important impact on outcomes. A comprehensive understanding of the anatomy of the right heart and surrounding structures is crucial. One way to optimize these interventions is by identifying the optimal fluoroscopic viewing angles along the S-curve of the tricuspid valve. Integration of chamber views using multimodality imaging (multislice computed tomography, fluoroscopy, and echocardiography) may increase operator confidence and reduce procedural duration, radiation exposure, contrast volume, and complication rates.
