Reverse remodeling after endoventricular circular patch plasty in the mid-term period

It has been reported that surgical repair of anterior left ventricular (LV) aneurysms is associated with reverse remodeling and improved myocardial function in the inferior LV wall. We evaluated wall motion in RCA territory using QGS in the mid-term period after endoventricular circular patch plasty (EVCPP). Eighteen patients, who underwent EVCPP, were studied by QGS before, and in the early and mid-term periods after surgery. Ten patients underwent CABG to the RCA because of RCA lesions (group B) and the other 8 patients did not have CABG to the RCA (group N). Regional wall thickening function was evaluated by the change in wall thickness through end-systole and end-diastole. We evaluated the RCA territory remote from the incision line of the EVCPP. Regional wall thickness improved significantly in the mid-term period after EVCPP in both groups. Although preoperative wall thickness was worse in group B than in group N, postoperative wall motion in group B was improved as well as in group N in the mid-term period. Inferior LV wall motion improved in patients with and without CABG in the mid-term period. We conclude that reverse remodeling occurred in the mid-term period after EVCPP.
