OBJECTIVE: We evaluated left ventricular dimensions and shape in the patients with postinfarction LV aneurysm before and after different techniques of ventricular reconstruction. METHODS: From January 1997 to December 2003, 158 patients underwent LV aneurysm repair. There were 152 men and 6 women, with a mean age 50+/-8.4 years. Ventricular reconstruction was performed by using linear plasty of the Cooley technique in 35 patients, septal plasty of the Stoney technique-in 57 patients, and endoventriculoplasty of the Dor technique-in 66 patients. Left ventricular volumes and dimensions, global and contractile left ventricular function, diastolic sphericity were analyzed before and after operation over a period of 10 days to 5 years. RESULTS: The EchoCG studies showed a significant postoperative improvement of the LV contracting function regardless of LV plasty technique used. The index of sphericity changed from 0.71+/-0.08 to 0.72+/-0.06 after linear plasty, from 0.71+/-0.05 to 0.73+/-0.07 after septal plasty, from 0.74+/-0.06 to 0.56+/-0.05 after endoventriculoplasty. The hospital mortality rate was 6.3%. There is no significant difference in hospital mortality rates between the different techniques of LV aneurysm repair. CONCLUSIONS: Our results show the effectiveness of different techniques of LV aneurysm repair, when the differentional approach to choice an adequate method of ventricular reconstruction was applied.
