Use of Three-Dimensional Intracardiac Echocardiography Catheter in the Evaluation of Prosthetic Pulmonary Valves after Transcatheter Replacement

J Am Soc Echocardiogr. 2024 Feb;37(2):226-236. doi: 10.1016/j.echo.2023.10.006. Epub 2023 Oct 14.


Transcatheter pulmonary valve replacement (TPVR) is commonly performed in patients with congenital heart disease as a safe alternative to replacement via open heart surgery. Intracardiac echocardiography (ICE) is a useful technique for evaluating multiple structures that are difficult to assess by other echocardiographic techniques, particularly the pulmonary valve. To our knowledge, the use of three-dimensional (3D) ICE catheters to evaluate prosthetic valves after TPVR has not been reported. Three-dimensional ICE catheters offer a comprehensive evaluation of transcatheter-deployed pulmonary valves through 3D, 3D color, xPlane, and multiplane reconstruction. The aim of this study is to demonstrate the feasibility of using 3D ICE catheters, outline their role in evaluating post-TPVR deployment success and complications, consider their additive value to two-dimensional ICE, and present our institutional experience with it in 50 cases of TPVR.
