“…A combination of multi-slice CT (MSCT) and 3D TEE produces a more ideal model compared with MSCT alone [33,34]. Fujita et al [35] developed a preoperative algorithm encompassing chest X-ray, echocardiography and 3D printing for the preoperative evaluation of congenital heart diseases. Although the algorithm minimizes potential misunderstandings of cardiac anomalies, it also brings unnecessary imaging examinations and additional costs.…”

“…Furthermore, in the transcatheter implantation era, the choice of a sutureless device with a larger EOA ensures a great Valve-in-Valve feasability. (14) A limitation to our analysis consists of the use of projected EOAs values provided by the manufacturers. As a matter of fact, in the immediate intraoperative/ postoperative period, considering the hemodynamic variability due to the surgical catecholamine stress and volume load, the use of the continuity equation as a reliable method to estimate the EOA is still debated.…”

Objective: Sutureless aortic valve replacement has recently been introduced as an alternative to conventional surgery to minimize the operative risk in elderly patients, shortening the cardiopulmonary bypass time and enhancing the minimally invasive approach. The aim of our study is to demonstrate that the sutureless bioprosthesis, compared to a conventional sutured prosthesis, has a corresponding larger effective orifice area, resulting in a better hemodynamic performance of the left ventricle. Materials and methods:In this prospective observational study, between January 2014 and September 2015, among our population of 37 sutureless aortic valve replacements, we examined 17 patients (sutureless, A group), in which a second measurement with a standard stented valve sizer has been performed during surgery. As a control group, we analyzed 10 additional aortic valve replacements who received conventional stented bioprosthesis (sutured, B group), in which an additional measurement with the sutureless sizer has been used to compare size and effective orifice areas differences between the sutureless and the sutured valves for any given annulus. Results:The size of the implanted bioprosthesis was 23,1 ± 1,9 mm and 23 ± 1,6 mm for the sutureless and sutured groups, respectively. In both groups, there were significative differences between the effective orifice areas of the implanted and the control sized prosthesis, always in favour of the sutureless valve (sutureless, A group: 2,6 ± 0,3 vs 1,4 ± 0,0 cm2, p < 0,001; sutured, B group: 1,5 ± 0,2 vs 2,9 ± 0,3 cm2, p < 0,001). Conclusions:Previous studies compared nominal sizes regardless of the effective orifice areas. For the first time, we analyzed the areas of the sutureless versus sutured bioprosthesis. For every single patient considered, the effective orifice area was significantly larger with the sutureless rather than with the sutured bioprosthesis that could fit. In sutureless aortic valve replacements, the benefits go far beyond the cardiopulmonary bypass and cross-clamp time reduction, providing larger areas and less risk of patient-prosthesis mismatch.

“…In addition to objectivity and reproducibility, selection of cardiac phase is crucial for the assessment and production of 3D printed models [8,25]. Recent studies reported the advanced feasibility of 3D printed models for TAVI procedures, such as ex vivo studies of valve-in-valve procedures [26].…”

“…SHDs refer to 'non-coronary cardiovascular disease' that can be treated by trans-catheter interventions; they range from pediatric and adult CHD to acquired heart valvular disease [8,9,[19][20][21][22][23][24][25][26][27][28][29][30][31] and other cardiovascular diseases. For less-invasive non-openheart interventions, precise 3D anatomy is crucial for from diagnosis, to procedural planning and simulation of trans-catheter intervention (Fig.…”

Cardiovascular three-dimensional (3D) printing models have been focused as an emerging technology. Using 3D volume dataset with the high-quality image obtained from CT, MRI or echocardiography, 3D printing models are produced and can provide tangible spatial perception for cardiovascular anatomy and diseases to conventional two-dimensional diagnostic imaging. Recent studies have shown the expanding feasibility of 3D printing models from procedural planning and simulation for surgical or trans-catheter interventions to training, education and communication for medical professionals and patients, particularly in complex congenital heart disease, structural heart disease, and hybrid cardiovascular surgery. With 3D printing technology and material engineering, 3D printing models can replicate not only the morphology but also the function that allows advanced physiological evaluation, procedural simulation, and a platform to 3D bio-printing. This review summarizes cardiovascular 3D printing model workflow from data acquisition to production and discusses clinical applications of 3D printing models.
