ABSTRACT
Objective To investigate the hemodynamic changes before and after Revivent surgery in patients with left ventricular apical aneurysm by cardiac magnetic resonance imaging ( CM R ) 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 CM R 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 T here were significant differences between preoperation and 1 month after operation for the measurements of LVEDV ,LVESV , LVEDd and LVEF by both CM R and echocardiography ( all P < 0 .05 ) . Compared with preoperation , LVESd decreased significantly 12 months after operation ( P <0 .01) . However ,there were no significant differences between preoperation and 1 or 12 months after operation for the measurements of SV ,SVI ,CO and CI ( all P > 0 .05 ) . T he consistency between CM R and echocardiography measurements was good . Conclusions Revivent surgery provides an effective and feasible treatment for patients with left ventricular apical ventricular aneurysm . T he dual‐modality imaging with CM R and echocardiography are reliable technical means to evaluate the changes of left ventricular heamodynamiscs during the perioperative period of Revivent
