“…Three-dimensional printing has the advantage of displaying all the elements required to adequately select an occluder that will match with the complex PVL shape. Location, size, number and morphology of PVL, together with the relationships with the valve and the surrounding structures, are depicted in a condensed manner in the 3D printed models [ 15 , 16 , 22 , 23 ].…”

Background: Percutaneous closure of paravalvular leak (PVL) has emerged as an alternative to surgical management in selected cases. Achieving complete PVL occlusion, while respecting prosthesis function remains challenging. A multimodal imaging analysis of PVL morphology before and during the procedure is mandatory to select an appropriate device. We aim to explore the additional value of 3D printing in predicting device related adverse events including mechanical valve leaflet blockade, risk of device embolization and residual shunting. Methods: From the FFPP registries (NCT05089136 and NCT05117359), we included 11 transcatheter PVL closure procedures from three centers for which 3D printed models were produced. Cardiac CT was used for segmentation for 3D printed models (3D-heartmodeling, Caissargues, France). Technology used a laser to fuse very fine powders (TPU Thermoplastic polyurethane) into a final part-laser sintering technology (SLS) with an adapted elasticity. A simulation on 3D printed model was performed using a set of occluders. Results: PVLs were located around aortic prostheses in six cases, mitral prostheses in four cases and tricuspid ring in one case. The device chosen during the simulation on the 3D printed model matched the one implanted in eight cases. In the three other cases, a similar device type was chosen during the procedures but with a different size. A risk of prosthesis leaflet blockade was identified on 3D printed models in four cases. During the procedure, the occluder was removed before release in one case. In another case the device was successfully repositioned and released. In two patients, leaflet impingement was observed post-operatively and surgical device removal had to be performed. Conclusion: In a case-series of complex transcatheter PVL closure procedures, hands-on simulation testing on 3D printed models proved its usefulness to plan and facilitate these challenging procedures.

“…Additional costs per model are required, however, these costs could be balanced by the reduction in the number of devices used and the reduction in adverse events in complex cases [ 23 ]. When considering the cost of a 3D printed model, a global cost-analysis of the procedure should be performed.…”

“…Successful planning of valve interventions others than CHD, TAVI, and mitral valve repair/ replacement (MVR) on 3DPSP were described during Ozaki repairs of the aortic valve [72], tricuspid valve-in-valve replacement [73], surgical tricuspid valve repair [74], and transcatheter tricuspid valve repair by MitraClip (Abbott, Menlo Park, CA, USA) implantation [75]. In the setting of surgical aortic valve replacement (SAVR), 3DPSP was used to plan surgery after previous coronary artery bypass graft [76], or transcatheter closure of paravalvular regurgitation after SAVR [77,78]. Moreover, 3DPSP can be used to simulate left ventricular assist devices implantation [79], and ease left ventricular inflow cannula placement with the help of a 3D printed exoskeleton [80].…”

“…Motwani et coworkers described the utility of rapid prototyping models from CCT in several cases of aortic paravalvular leak. Giving a novel approach by transcatheter closure of paravalvular leak, 3D models allowed simulation of various treatment devices, with satisfactory outcomes [ 48 ]. Another application of modeling for procedural simulation was recently studied by Engelhardt and colleagues, who printed for the first time an integral mitral valve apparatus.…”

The increasing complexity of cardiovascular interventions requires advanced peri-procedural imaging and tailored treatment. Three-dimensional printing technology represents one of the most significant advances in the field of cardiac imaging, interventional cardiology or cardiovascular surgery. Patient-specific models may provide substantial information on intervention planning in complex cardiovascular diseases, and volumetric medical imaging from CT or MRI can be translated into patient-specific 3D models using advanced post-processing applications. 3D printing and additive manufacturing have a great variety of clinical applications targeting anatomy, implants and devices, assisting optimal interventional treatment and post-interventional evaluation. Although the 3D printing technology still lacks scientific evidence, its benefits have been shown in structural heart diseases as well as for treatment of complex arrhythmias and corrective surgery interventions. Recent development has enabled transformation of conventional 3D printing into complex 3D functional living tissues contributing to regenerative medicine through engineered bionic materials such hydrogels, cell suspensions or matrix components. This review aims to present the most recent clinical applications of 3D printing in cardiovascular medicine, highlighting also the potential for future development of this revolutionary technology in the medical field.
