“…Segmentation is a multi-step process. Prior to segmentation, the acquired diagnostic imaging dataset is exported into a digital imaging and communication in medicine (DICOM) format, which can be universally used in digital modeling softwares without the need for file type conversion [16]. Several medical image segmentation softwares are available; some of these are open-source and freely accessible, while others are commercial, licensed products.…”

Three dimensional (3D) printing, which consists in the conversion of digital images into a 3D physical model, is a promising and versatile field that, over the last decade, has experienced a rapid development in medicine. Cardiovascular medicine, in particular, is one of the fastest growing area for medical 3D printing. In this review, we firstly describe the major steps and the most common technologies used in the 3D printing process, then we present current applications of 3D printing with relevance to the cardiovascular field. The technology is more frequently used for the creation of anatomical 3D models useful for teaching, training, and procedural planning of complex surgical cases, as well as for facilitating communication with patients and their families. However, the most attractive and novel application of 3D printing in the last years is bioprinting, which holds the great potential to solve the ever-increasing crisis of organ shortage. In this review, we then present some of the 3D bioprinting strategies used for fabricating fully functional cardiovascular tissues, including myocardium, heart tissue patches, and heart valves. The implications of 3D bioprinting in drug discovery, development, and delivery systems are also briefly discussed, in terms of in vitro cardiovascular drug toxicity. Finally, we describe some applications of 3D printing in the development and testing of cardiovascular medical devices, and the current regulatory frameworks that apply to manufacturing and commercialization of 3D printed products.Cells 2020, 9, 742 2 of 33 Cells 2020, 9, 742 3 of 33 in digital modeling softwares without the need for file type conversion [16]. Several medical image segmentation softwares are available; some of these are open-source and freely accessible, while others are commercial, licensed products. From the DICOM dataset, the target anatomic geometry is identified and segmented based on properties such as contrast or brightness [17]. As a result, segmentation masks are created such that pixels with the same intensity range are grouped and converted into 3D digital models using rendering techniques. These segmented digital models are then exported out in the standard tessellation language (STL) file type, which is the industry standard for 3D objects and 3D printing software [17]. Nevertheless, STL files do not contain color information and in order to print in multiple colors, a different file format will need to be used. For example, virtual reality modeling language (VRML) and additive manufacturing file format (AMF) provide multiple color and material options [18]. Once segmentation is completed, the final 3D digital model may be further modified within computer-aided design (CAD) software. The main post-processing adjustments of the 3D model are: Repairing errors and discontinuities that sometimes arise in the image segmentation and exporting processes, smoothing of the surface of the model due to scaling errors resulting from the resolution of the original medical image, and addition of other...

“…The use of 3D printing in medicine was a natural consequence of its development [6][7][8][9]. In surgery, 3D printing allows for a better understanding of the operating field on which the surgeon will work during a complicated operation, as well as the creation of tools tailored individually to the patient's anatomical conditions and personalized implants [4,[10][11][12][13][14][15][16][17][18][19][20]. Sometimes the problem of the availability of equipment necessary to treat patients is related to its price.…”

Background Recent advances in 3D printing technology, and biomaterials are revolutionizing medicine. The beneficiaries of this technology are primarily patients, but also students of medical faculties. Taking into account that not all students have full, direct access to the latest advances in additive technologies, we surveyed their opinion on 3D printing and education in this area. The research aimed to determine what knowledge about the use of 3D printing technology in medicine, do students of medical faculties have. Methods The research was carried out in the form of a questionnaire among 430 students of the Medical University of Silesia in Katowice (Poland) representing various fields of medicine and health sciences. The questions included in the survey analyzed the knowledge of the respondents for 3D printing technology and the opportunities it creates in medicine. Results The results indicate that students do have knowledge about 3D printing obtained mainly from the internet. They would be happy to deepen their knowledge at specialized courses in this field. Students appreciated the value of 3D printing in order to obtain accurate anatomical models, helpful in learning. However, they do not consider the possibility of complete abandonment of human cadavers in the anatomy classes. Their knowledge includes basic information about current applications of 3D printing in medicine, but not in all areas. However, they have no ethical doubts regarding the use of 3D printing in any form. The vast majority of students deemed it necessary to incorporate information regarding 3D printing technology into the curriculum of different medical majors.

“…It is a fabrication technique used to transform digital images into physical objects in a layer-by-layer approach where images from CT or MRI (digital imaging and communication in medicine [DICOM] files) are converted to a standard tessellation language (STL) file by software and finally printed by stereolithography (a special form of laser printing). [17][18][19][20][21][22][23][24] This software also enables us to make more accurate surfaceto-surface virtual measurements without printing. Although anatomical studies for educational purposes with 3D printing have been done in carotid arteries, there is no studies available regarding pre-procedural planning, practicing, and device selection.…”

Karotis arter stent planlamasında 3D baskılı anatomik karotis modellerin değerlendirilmesi ÖZ Amaç: Bu çalışmada üç boyutlu baskılı anatomik modellerin işlem öncesi planlanan, uygulama ve karotis arter stent ve emboli önleme cihazının boyut ve yerleşiminin belirlenmesindeki muhtemel rolü araştırıldı. Ça lış ma pla nı: Ocak 2017-Şubat 2019 tarihleri arasında emboli önleme cihazı ile karotis arter stentleme yapılan toplam 16 hasta (10 erkek, 6 kadın; ort. yaş 75.6±4.7 yıl; dağılım, 68-81 yıl) retrospektif olarak incelendi. Boyut, distal önleme cihazı kullanılarak aynı marka stent ile işlem sırası yapılan anjiyografi sonuçlarına göre belirlendi. Tanıda kullanılan işlem öncesi bilgisayarlı tomografi anjiyografi görüntüleri elde edildi ve üç boyutlu baskı yöntemi ile modellendi. Stent ve önleme cihazlarının boyutu ve implantasyon bölgelerine ilişkin işlem öncesi ve üç boyutlu veriler karşılaştırıldı. Bul gu lar: Stent ve emboli önleme cihazı boyutları, manuel üç boyutlu modelden ve yazılımdan segmentasyon görüntülerinden elde edilen ölçümler için benzer ve asıl kullanılanlardan küçük idi. Karotis arter darlığı oranı da, manuel ve yazılım yöntemler ile benzerdi; ancak, kantitatif anjiyografik ölçümlere kıyasla daha düşük idi. Manuel ve yazılım modelleri ile tespit edilen cihaz implantasyon yerleri, gerçekte kullanılandan farklı idi. So nuç:Üç boyutlu modeller ile işlemin planlanması ve uygulanması, operatöre bağımlı değişkenleri azaltabilir, ameliyat zamanını kısaltabilir, radyasyon maruziyetini düşürebilir ve işlem başarısını artırabilir.
