Presented at the Sixth Annual Cardiothoracic Techniques and Technologies Meeting 2000, Ft Lauderdale, FL, Jan 27–29, 2000.
Background. Traditionally, repair of left ventricular aneurysms has been limited to patients with large localized ventricular aneurysms. Repair of dyskinetic segments in the setting of poor left ventricular function is still contentious.
Methods. Forty patients underwent geometric endo-ventricular repair, a new technique of ventricular aneurysm repair, over a 2-year period. Two groups of patients undergoing coronary artery bypass grafting (CABG) for left ventricular dysfunction in the same time period were reviewed. Group 1 comprised 23 consecutive patients who underwent geometric endo-ventricular repair along with CABGs, whereas group II consisted of 22 patients who underwent CABG alone.
Results. The early mortality was 9.1% in group I (1 cardiac, 1 noncardiac) and 0 in group II (NS). New York Heart Association class was remarkably improved from 3.4 to 1.4 (p < 0.05) in group I and to a lesser extent in group II (3.7 ± 0.5 versus 2.3 ± 0.5). Diastolic dimension of left ventricle was significantly reduced from 5.6 cm to 4.4 cm (p < 0.05) in group I and virtually unchanged in group II. There was one late death in each of the groups.
Conclusions. This technique of geometric left ventricular aneurysm repair is useful in patients with dyskinetic segments and may help in reducing cardiac size.
