biostudies-literatureUnknown6(4)Chadderdon SMPatients with severe symptomatic tricuspid regurgitation face a significant dilemma in treatment options, as the yearly mortality with medical therapy and the surgical mortality for tricuspid repair or replacement are high. Transcatheter edge-to-edge repair (TEER) for the tricuspid valve is becoming a viable option in patients, although procedural success is dependent on high-quality imaging. While transesophageal echocardiography remains the standard for tricuspid TEER procedures, intracardiac echocardiography (ICE) with three-dimensional (3D) multiplanar reconstruction (MPR) has many theoretical and practical advantages. The aim of this article was to describe the in vitro wet lab-based imaging work done to facilitate the best approach to 3D MPR ICE imaging and the procedural experience Structural heart : the journal of the Heart Team100071https://www.ebi.ac.uk/biostudies/studies/S-EPMC10242583biostudies-literatureThree-Dimensional Intracardiac Echocardiography for Tricuspid Transcatheter Edge-to-Edge Repair.PMC10242583Eleid MFSong HKNakamura MMakkar RZahr FEBabaliaros VKodali SKoulogiannis KPDeuschl FThaden JJHahn RTGreenbaum ALim DSGray WANarang ADavidson CChadderdon SMGleason PHawthorne KGrayburn PMarcoff LSmith RLfalseThree-Dimensional Intracardiac Echocardiography for Tricuspid Transcatheter Edge-to-Edge Repair.Patients with severe symptomatic tricuspid regurgitation face a significant dilemma in treatment options, as the yearly mortality with medical therapy and the surgical mortality for tricuspid repair or replacement are high.
