Key result
3D TEE-guided percutaneous valve-in-valve therapy proves feasible in aortic, mitral, and tricuspid positions across 3 cases.
Case Report (n=3)
Percutaneous valve-in-valve implantation is a feasible procedure for dysfunctional bioprosthetic valves in multiple positions, heavily reliant on multimodality imaging for guidance.
Supports feasibility of valve-in-valve implantation; leaves open durability, safety, and need for prospective trials.
Percutaneous valve-in-valve therapy is a life-saving procedure for patients at high risk of reoperation due to dysfunctional bioprosthetic valves. We have reviewed 3 typical cases of a valve-in-valve procedure using high-quality images to demonstrate the suitability of this method for aortic, mitral, and tricuspid positions. Three-dimensional transesophageal echocardiography combined with other modalities such as computerized tomography and fluoroscopy are key elements for anesthesia and procedural guidance, especially as immediate tools to assess valvular function and specific procedure-related complications.

Hai et al. (2017) conducted a case report in Dysfunctional bioprosthetic valves (n=3). Percutaneous valve-in-valve therapy was evaluated. Percutaneous valve-in-valve therapy was demonstrated to be suitable for aortic, mitral, and tricuspid positions in 3 typical cases, guided by 3D transesophageal echocardiography.
