ObjectiveTo evaluate the effects of modified left ventricular reconstruction (LVR) and linear repair (LR) to post-infarct left ventricular aneurysm (LVA) and summarize the surgical experience of LVA. MethodsFrom May 2004 to December 2011, 47 patients were admitted in the Department of Cardiovascular Surgery, Renji Hospital Affiliated to Medical College of Shanghai Jiaotong University. There were 25 patients underwent LVR (group LVR, including 21 males and 4 females), 18 patients underwent LR (group LR, including 14 males and 4 females) and 4 patients underwent directly sutured (including 3 males and 1 female). Among them, 42 patients underwent coronary artery bypass grafting (CABG). During 6-24 months'follow-up, left ventricular ejection fraction (LVEF), quality of life and activity were measured. ResultsPostoperative LVEF was significantly higher than preoperative LVEF in group LVR(49.2%±13.6% vs. 32.5%±12.9%, P < 0.05) and group LR (47.5%±11.6% vs. 36.9%±11.6%, P < 0.05). One patient died in LR group (5.5%) and 1 died in LVR group (4.0%), no death occurred in directly sutured surgery. Total mortality was 4.2%. ConclusionLVR and LR are both effective treatment for LVA. Personalized treatment can receive satisfactory short-and long-term outcomes.
