ABSTRACT=A 59-year-old female was admitted to the emergency department for heart  failure (HF), NYHA IV, showing an anterior, evolved myocardial infarction (MI)  with a  wide apical left ventricular aneurysm (LVA),  ejection fraction (EF) 24% and global longitudinal strain (GLS) -5.5% by echo. Cardiac magnetic resonance imaging (MRI) confirmed an apical LVA without thrombus, EF 20%, and a transmural delayed enhancement in the myocardium wall. Coronarography showed a 3-vessel disease with occluded proximal left anterior descending (LAD) and proximal right coronary artery (RCA). Based on cardiac computed tomography (CT) scan, we decided to generate a 3D print model of heart, for a better prediction of residual LV volumes.  After LVA surgery plus complete functional revascularization, an optimal agreement was found between predicted and surgical residual LV end-diastolic (24.7 vs. 31.8 mL/m2) and end-systolic (54.1 vs. 69.4 mL/m2) volumes, with an improvement of NYHA class, from IV to I. The patient was discharged uneventful and at 6- and 12-month follow-up, the NYHA class and LV volumes were found unchanged. This is a second report describing the use of 3D print model for the preoperative planning of surgical management of LVA, being the first report described by Jacobs S. et al. (1) among 3 patients, one with a malignant tumor and the remaining two patients with LVA. This article was focused on the  use  of 3D print model to optimize surgical planning and individualize the  treatment of LVA associate with complete functional revascularization, leading a complete recovery of LV function with  favorable outcome.
