Objective To investigate the feasibility and diagnostic value of a preoperative transthoracic echocardiography‐guided three‐dimensional printed model ( TTE ‐guided 3 DPM ) for the assessment of structural heart disease ( SHD ). Methods Fourty‐four patients underwent cardiac surgery at Tianjin Chest Hospital. The patients were preoperatively assessed using TTE ‐guided 3 DPM , which was compared to conventional three‐dimensional transthoracic echocardiography (3D TTE ) along with direct intraoperative findings, which were considered the “gold standard.” Twelve patients had SHD , including four with mitral prolapse, two with partial endocardial cushion defects, two with secondary atrial septal defects, two with rheumatic mitral stenosis, one with tetralogy of Fallot, and one with a ventricular septal defect ( VSD ). Thirty‐two patients who did not have SHD s were designated as the negative control group. Results The sensitivity and specificity of the TTE ‐guided 3 DPM were greater than or equal to those of the 3D TTE . The P ‐value of the McNemar test of 3D TTE was >.05, which indicates that the difference was not statistically significant (Kappa = 0.745, P < .001). The P ‐value of the McNemar test of TTE ‐guided 3 DPM was >.05, which indicates that the difference was not statistically significant (Kappa = 0.955, P < .001). A comparison of 3D TTE and TTE ‐guided 3 DPM resulted in a P ‐value >.05, which indicates that the difference was not statistically significant (Kappa = 0.879, P < .001). TTE ‐guided 3 DPM displayed the 3D structure of SHD s and cardiac lesions clearly and was consistent with the intra‐operative findings. Conclusion Transthoracic echocardiography‐guided three‐dimensional printed model ( TTE ‐guided 3 DPM ) provides essential information for preoperative evaluation and decision making for patients with SHD s.
