“…Cardiovascular magnetic resonance (CMR) has certain advantages over cardiac CT in displaying the heart's soft tissue or valves [34][35][36][37]. Significant improvements to the spatial and temporal resolutions of transthoracic and transesophageal 3D echocardiography make it another alternative technology for acquiring reliable source data for 3D printing [38][39][40][41].…”

Three-dimensional printing for cardiovascular diseases: from anatomical modeling to dynamic functionality

Three-dimensional (3D) printing is widely used in medicine. Most research remains focused on forming rigid anatomical models, but moving from static models to dynamic functionality could greatly aid preoperative surgical planning. This work reviews literature on dynamic 3D heart models made of flexible materials for use with a mock circulatory system. Such models allow simulation of surgical procedures under mock physiological conditions, and are; therefore, potentially very useful to clinical practice. For example, anatomical models of mitral regurgitation could provide a better display of lesion area, while dynamic 3D models could further simulate in vitro hemodynamics. Dynamic 3D models could also be used in setting standards for certain parameters for function evaluation, such as flow reserve fraction in coronary heart disease. As a bridge between medical image and clinical aid, 3D printing is now gradually changing the traditional pattern of diagnosis and treatment.

The placement of a left atrial appendage occlusion (LAAO) device can be a technically challenging transcatheter‐based procedure. Key challenges include accurate pre‐procedural device sizing and proper device positioning at the LAA ostium to ensure sufficient device anchoring and avoid peri‐device leaks. To address these challenges, 3D printing (3DP) of LAA models has recently emerged in the literature, first being described in 2015. We present a review of the benefits and drawbacks of employing this technology for LAAO procedures. Pre‐procedurally the use of 3DP can consistently and accurately determine LAAO device size over standard of care approaches. Intra‐procedurally 3DP's impact entailed a statistically significant decrease in the number of devices used per procedure, as well as in the fluoroscopic time and dose. Post‐procedurally, there is some evidence that 3DP could reduce the rate of peri‐device leaks, with limited data on its effect on complication rates. Based on existing evidence, we recommend the focused application of 3DP to cases of complex LAA anatomy and for the training of proceduralists. Lastly, we address the emergence of next generation LAAO devices and AR/VR systems that could limit even this narrow window of clinical benefit afforded by 3DP.

“…In previous studies, the original data of the 3D model were derived from CT and MRI results. 10,11 Combining 3DP with ultra sound imaging, constructing the 3DPM of structured heart disease using the original data of 3D echocardiography, 12 and evaluating preoperative information may provide more accurate information for clinical applications. 8,9 However, CT exam ination involves ionizing radiation, and MRI is associated with strict selection of patients, high cost, and a long examination length; therefore, it is difficult to use these technologies to acquire origi nal data for the 3D model.…”

“…Furthermore, because echocardiography is a simple process with little patient selectivity, no radiation, and good repeatability, it has been used to construct models of the left atrial appendage in recent years. 10,11 Combining 3DP with ultra sound imaging, constructing the 3DPM of structured heart disease using the original data of 3D echocardiography, 12 and evaluating preoperative information may provide more accurate information for clinical applications.…”
