Does surgical intervention planning using 3D models based on MRI reduce operative times in patients with postinfarction left ventricular aneurysms?
Absolute Event Rate: 60% vs 71%
p-value: p=0.043
MRI-based 3D modeling for surgical planning of post-infarction left ventricular aneurysms significantly reduces full perfusion time during cardiopulmonary bypass.
MRI-based 3D planning may aid LV aneurysm repair; hypothesis-generating and requires randomized validation before practice change.
Aim. To evaluate the results of surgical intervention planning using three-dimensional models based on magnetic resonance imaging in patients with postinfarction left ventricular aneurysms. Material and Methods. Two groups of patients with postinfarction left ventricular aneurysm (PLVA) were included in the study, totaling 41 patients. The first (experimental) group included 17 patients diagnosed with PLVA by magnetic resonance imaging (MRI), and surgical intervention planning was performed using a 3D model of the heart. The control group comprised 24 patients in whom PLVA was diagnosed by echocardiography (TTE) or ventriculography, and surgical intervention planning was performed using traditional two-dimensional slice images. Results. Comparison of full perfusion under cardiopulmonary bypass (CPB) showed statistically significant differences between the groups: this parameter was 60 [56; 68] min in group 1 vs. 71 [61; 84] min in group 2, which was significantly higher (p = 0.043). There were no significant differences in total operation time (280 [265; 320] min in group 1 vs. 263 [248; 283] min in group 2, p = 0.055), overall CPB time (93 [86; 109] min in group 1 vs. 104 [83; 109] min in group 2, p = 0.653), and partial CPB time (31 [26; 39] min in group 1 vs. 27 [21; 32] min in group 2, p = 0.127). Conclusion. The use of 3D models to support surgeons for PLVA correction makes it possible to determine the type of reconstructive surgery, practice the main stages of the upcoming intervention, and reduce the time of full perfusion under CPB during its implementation.

Кушнарев et al. (2022) conducted a cohort in postinfarction left ventricular aneurysms (n=41). Surgical planning using 3D models based on MRI vs. Surgical planning using traditional 2D slice images was evaluated on Full perfusion time under cardiopulmonary bypass (CPB) (p=0.043). Surgical planning using 3D models based on MRI significantly reduced full perfusion time under cardiopulmonary bypass compared to traditional 2D imaging (60 vs 71 minutes; p=0.043).
