“…Another 24 studies (11.3%) applied a mixture of modalities across included patients (CCT and CMR, n = 21; CCT and 3D TEE, n = 2; and CCT, CMR, and 3D TEE, n = 1), while 2 studies (<1%) merged data from several modalities; 4 papers (1.9%) did not provide information on the sources of images. Echocardiography-derived 3DPSPs were limited to the depiction of cardiac valves (n = 16), 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ventricular or atrial septal defects (n = 3), 26 , 35 , 36 the left atrial appendage (n = 3), 17 , 37 , 38 or fetal hearts (n = 1). 39 …”

“…printing-guided percutaneous transcatheter closure of secundum ASD with rim deficiency in six patients [10]. This was followed by a report by Zhu et al in patients with multiple secundum ASD [11] and finally by Velasco Forte et al in patients with superior sinus venosus ASD and partial anomalous pulmonary venous drainage [12]. The current study found through 3D printed heart models that the lower edge of the inferior sinus venosus ASD is composed of the entrance of the inferior vena cava and the inferior wall of the left atrium, which was almost in a plane, and its shape was similar to the 'T' glyph or 'funnel' structure.…”

Background Multiple atrial septal defects (ASD) with an inferior sinus venosus defect (SVD) have always been considered to be contraindications for interventional therapy. On the basis of early experience using a patent ductus arteriosus (PDA) occluder for interventional treatment for inferior ASD, this study investigated the feasibility of transcatheter closure of multiple ASDs with an inferior SVD under the guidance of threedimensional (3D) printed heart models.

“…Automation of these processes through dedicated software would significantly increase the potential usefulness of this method. In the literature there are examples where more sophisticated software is applied to prepare 3D models (Mimics 19.0, Materialise, Leuven, Belgium), which significantly reduces the model preparation time [26][27][28]. Unfortunately, license cost precludes everyday use of such software.…”

Introduction: Transcatheter closure of paravalvular leak (PVL) is still a demanding procedure due to the complex anatomy of PVL channels and risk of interference between the implanted occluder and surrounding structures. Efforts are made to improve procedural outcomes in transcatheter structural heart interventions by establishing treatment strategy in advance with the use of 3D-printed physical models based on data obtained from cardiac computed tomography (CT) studies.Aim: In this feasibility study 3D printing of PVL models based on data recorded during transesophageal echocardiography (TEE) examinations was evaluated.Material and methods: 3D-TEE data of patients with significant PVL around mitral valve prostheses were used to prepare 3D models. QLab software was used to export DICOM images in Cartesian DICOM format of each PVL with the surrounding tissue. Image segmentation was performed in Slicer, a free, open-source software package used for imaging research. Models were printed to actual size with the Polyjet printer with a transparent, rigid material. We measured dimensions of PVLs both in TEE recordings and printed 3D models. The results were correlated with sizes of occluding devices used to close the defects.Results: In 7 out of 8 patients, there was concordance between procedurally implanted occluders and pre-procedurally matched closing devices based on 3D-printed models.Conclusions: 3D-printing from 3D-TEE is technically feasible. Both shape and location of PVLs are preserved during model preparation and printing. It remains to be tested whether 3D printing would improve outcomes of percutaneous PVL closure.
