AI Article Synopsis
- - Paravalvular leaks, occurring in about 15% of patients after mitral valve surgery, can lead to serious complications like heart failure, prompting the exploration of 3D-printed models to enhance interventional cardiology procedures.
- - Researchers analyzed 3D-transesophageal echocardiography data from 8 patients to create precise models of the leaks, using advanced software for imaging and a high-quality 3D printer.
- - The preparation and printing of these models took an average of 430.5 minutes, showing that while the process is technically possible, further studies are needed to determine if it improves the success rate of treating these leaks.
Article Abstract
Background: Paravalvular leaks can be detected in almost 15% of patients after mitral valve prosthesis implantation. This complication can result in congestive heart failure and hemolysis. Despite advancements in non-invasive imaging, percutaneous closure of paravalvular leaks is not always successful. Therefore, efforts are made to improve treatment outcomes by using 3D-printed models of defects as pre-procedural support for interventional cardiologists.
Methods: Retrospectively, 3D-transesophageal echocardiography recordings of 8 patients with clinically significant mitral paravalvular leaks were analyzed. Qlab Software was used to export DICOM images of each paravalvular leak channel, including surrounding tissue. Image segmentation was performed in 3D Slicer, a free, open-source software package used for imaging research. Models were printed to actual size with the poly jet Stratasys Objet 30 printer with a transparent, rigid material.
Results: Duration of model preparation and printing, as well as the total cost, was calculated. Mean total time of model preparation was 430.5 ± 196 minutes.
Conclusion: 3D-printing from 3D-transesophageal echocardiography is technically feasible. Both shape and location of paravalvular leaks are preserved during model preparation and printing. It remains to be tested if 3D-printing would improve outcomes of percutaneous paravalvular leaks closure.
