Comparative study of left ventricular hemodynamic changes after Revivent surgery by dual-modality imaging

Objective To investigate the hemodynamic changes before and after Revivent surgery in patients with left ventricular apical aneurysm by cardiac magnetic resonance imaging(CMR) and echocardiography. Methods Twenty-two cases with left ventricular apical aneurysm were examined by two-dimensional and three-dimensional transthoracic echocardiography 1 week before operation, 1 month and 12 months after operation, by CMR 1 week before operation and 12 months after operation.Left ventricular end-diastolic volume(LVEDV), left ventricular end-systolic volume (LVESV), left ventricular end-diastolic diameter (LVEDd), left ventricular end-systolic diameter (LVESd), left ventricular ejection fraction (LVEF), stroke volume (SV), stroke output index (SVI), cardiac output (CO) and cardiac output index(CI) were quantitatively measured and statistical analysis were performed. Results There were significant differences between preoperation and 1 month after operation for the measurements of LVEDV, LVESV, LVEDd and LVEF by both CMR and echocardiography (all P 0.05). The consistency between CMR and echocardiography measurements was good. Conclusions Revivent surgery provides an effective and feasible treatment for patients with left ventricular apical ventricular aneurysm. The dual-modality imaging with CMR and echocardiography are reliable technical means to evaluate the changes of left ventricular heamodynamiscs during the perioperative period of Revivent Key words: Echocardiography; Magnetic resonance imaging; Apical aneurysm; Revivent; Hemodynamics
