Ohira S, et al. - This study aimed at reporting the mid-term results of the surgical ventricular restoration procedure, called the endocardial linear infarct exclusion technique (ELIET), for ischaemic cardiomyopathy. Findings suggested ELIET as effective in reducing the ventricular volume and creating an ellipsoidal left ventricle.

Methods

• 43 consecutive patients who underwent surgical ventricular restoration with ELIET for ischaemic cardiomyopathy from 2006 to 2015 were analyzed.

Results

• At surgery, the mean age of patients was 65.3 ± 9.2 years and EuroSCORE II was 13.7 ± 12.0% (median 9.3%).
• In this study, the mean number of distal anastomoses of coronary artery bypass was 2.8 ± 1.5.
• Researchers performed a concomitant mitral procedure in 58.1% of patients.
• Observations revealed hospital mortality rate of 11.6% (5 patients).
• In 2 weeks after surgery, there appeared an improvement in ejection fraction from 24.1 ± 9.2% to 31.7 ± 8.2%.
• They noticed an effective reduction in the end-systolic left ventricular volume index, irrespective of performing a concomitant mitral procedure (reduction rate, ELIET: 35.6% vs ELIET + mitral: 39.2%).
• After ELIET, no worsening in the sphericity index of the left ventricle was evident and there appeared a significant improvement in the conicity index.
• As per estimations, the 5-year rates of survival and freedom from cardiac events were 71.3 ± 7.9 and 61.1 ± 8.3%, respectively.
• Univariate Cox hazard analysis suggested a significant association between a concomitant mitral procedure and cardiac events.
