Intravascular Ultrasound Guidance for Transcatheter Pulmonary Valve Replacement

Year: 2026

Type: article

Abstract: ranscatheter pulmonary valve replacement (TPVR) is used in the treatment of right ventricular outflow tract (RVOT) or conduit dysfunction and failed surgical bioprostheses.Computed tomography guides sizing but cannot provide intraprocedural feedback.Projection angiography cannot provide a true short-axis assessment of the RVOT geometry, achieved transcatheter heart valve (THV) expansion, or leaflet-defined geometric orifice area (GOA).Large-field 0.035-inch intravascular ultrasound (IVUS) provides an intraluminal tomographic perspective during structural valve interventions. 1 We assessed IVUS-derived RVOT geometry, THV expansion, and GOA vs angiography and echocardiographic follow-up data.This retrospective single-center analysis used prospectively collected records.The study protocol complied
