Medical 3-dimensional (3D) printing is emerging as a clinically relevant imaging
tool in directing preoperative and intraoperative planning in many surgical
specialties and will therefore likely lead to interdisciplinary collaboration
between engineers, radiologists, and surgeons. Data from standard imaging
modalities such as computed tomography, magnetic resonance imaging,
echocardiography, and rotational angiography can be used to fabricate life-sized
models of human anatomy and pathology, as well as patient-specific implants and
surgical guides. Cardiovascular 3D-printed models can improve diagnosis and allow
for advanced preoperative planning. The majority of applications reported involve
congenital heart diseases and valvular and great vessels pathologies. Printed
models are suitable for planning both surgical and minimally invasive procedures.
Added value has been reported toward improving outcomes, minimizing perioperative
risk, and developing new procedures such as transcatheter mitral valve
replacements. Similarly, thoracic surgeons are using 3D printing to assess
invasion of vital structures by tumors and to assist in diagnosis and treatment
of upper and lower airway diseases. Anatomic models enable surgeons to assimilate
information more quickly than image review, choose the optimal surgical approach,
and achieve surgery in a shorter time. Patient-specific 3D-printed implants are
beginning to appear and may have significant impact on cosmetic and life-saving
procedures in the future. In summary, cardiothoracic 3D printing is rapidly
evolving and may be a potential game-changer for surgeons. The imager who is
equipped with the tools to apply this new imaging science to cardiothoracic care
is thus ideally positioned to innovate in this new emerging imaging modality.
