Key result
RT-3D TEE reliably guides successful orthotopic tricuspid valved stent implantation in a preclinical model.
Why the study?
The value of real-time three-dimensional transesophageal echocardiography for guidance and assessment of orthotopic tricuspid valved stent implantation in the beating heart was assessed.
Case Report (n=4)
May guide preclinical imaging protocols for transcatheter tricuspid valves; leaves open human translation and safety data.
In this case report, the value of real-time three-dimensional transesophageal echocardiography (TEE) for guidance and assessment of orthotopic tricuspid valved stent implantation in the beating heart is assessed in four pigs. A full two-dimensional TEE evaluation of standardized parameters was conducted. Three-dimensional TEE provided dependable imaging of anatomical structures of the right side of the heart, the delivery system, and the valved stent, allowing easier orientation and more accurate views for the surgical team. Although visualization of the tricuspid valve in the porcine model is challenging, it contributed highly to the successful implantation of the tricuspid valved stent.

Pokorny et al. (2014) conducted a case report in Orthotopic tricuspid valved stent implantation (n=4). Real-time three-dimensional transesophageal echocardiography (TEE) was evaluated on Guidance and assessment of orthotopic tricuspid valved stent implantation. Real-time three-dimensional transesophageal echocardiography provided dependable imaging and contributed highly to the successful implantation of a tricuspid valved stent in a porcine model.
