Endoventricular Stepwise Plication for Left Ventricular Aneurysm

A 69-year-old man was treated with oral anticoagulation for the left ventricular (LV) aneurysm. Echocardiography revealed dyskinetic apex with a mobile thrombus. The estimated LV end-diastolic and end-systolic volume index (LVEDVI, LVESVI) was 76 and 44 ml/m2, respectively. After the LV was opened at the apex parallel to the left anterior descending artery, removal of LV thrombus was performed. LV volume was 70 ml, and diameter of LV aneurysm was 3 cm. After setting a neo-apex, the boundary between the normal and aneurysmal scar tissue were doubly encircled by a pledgeted 2-0 polypropylene suture, and preserved the same diameter as the "aneurysmal neck" (3 cm) in order to secure the minimal residual LV volume. Similarly, second and third circular stitches were placed toward the neo-apex to make the ventricle into an elliptical shape. A postoperative echocardiography showed a well-reconstructed physiologic shape, LV volume( LVEDVI 62 ml/m2, LVESVI 27 ml/m2), and improved LV function.
