Transseptal Left Heart Catheterization for a Patient With a Prosthetic Mitral Valve Using Live Three-Dimensional Transesophageal Echocardiography
- 57 Downloads
The images and videos presented in this article illustrate a diagnostic transseptal left heart catheterization for a patient with a prosthetic mitral valve guided by live three-dimensional (3D) transesophageal echocardiography. This method provided high-quality 3D imaging that was useful in guiding transseptal puncture and demonstrating prosthetic valve function during this evaluation.
