ABSTRACT
Aims and Objectives:
The objective of this study was to assess the clinical feasibility of using echocardiographic data to generate three‑dimensional models of normal and pathologic mitral valve annuli before and after repair procedures. Materials andMethods:
High‑resolution transesophageal echocardiographic data from five patients was analyzed to delineate and track the mitral annulus (MA) using Tom Tec Image‑Arena software. Coordinates representing the annulus were imported into Solidworks software for constructing solid models. These solid models were converted to stereolithographic (STL) file format and three‑dimensionally printed by a commercially available Maker Bot Replicator 2 three‑dimensional printer. Total time from image acquisition to printing was approximately 30 min.Results:
Models created were highly reflective of known geometry, shape and size of normal and pathologic mitral annuli. Post‑repair models also closely resembled shapes of the rings they were implanted with. Compared to echocardiographic images of annuli seen on a computer screen, physical models were able to convey clinical information more comprehensively, making them helpful in appreciating pathology, as well as post‑repair changes.Conclusions:
Three‑dimensional printing of the MA is possible and clinically feasible using routinely obtained echocardiographic images. Given the short turn‑around time and the lack of need for additional imaging, a technique we describe here has the potential for rapid integration into clinical practice to assist with surgical education, planning and decision‑making.Palavras-chave
