ABSTRACT
BACKGROUND:
The purpose of this study was to evaluate the fate of left atrioventricular valve regurgitation(LAVVR) following repair of complete atrioventricular septal defects (AVSDs). MATERIAL ANDMETHOD:
Between July 1984 and March 2002, repair of complete AV defects were performed in 77 patients. Mean age at surgery was 30.23+/-69.11 months (range 1 to 456). Echocardiograms of all survivors after isolated AVSDs correction were reviewed. LAVVR were evaluated with color doppler echocardiography in 64 survival periodically. On each study, LAVVR severity was graded on a 1 to 4 scale, based upon the size of the regurgitated jet.RESULT:
Mild deterioration of LAVV function was fairly common. LAVVR severity increased by >1 grade in 19 patients (30.2%) during the course of the study. However, the deterioration in LAVVR function occurred primarily between 12 and 24 months postoperatively. After the initial 24 postoperative months, LAVVR worsened on only 8 occasions and in each instance worsened by only 1 grade. Deterioration more than 3+ LAVVR occurred in only 3 patients. And deterioration to 4+ LAVVR was not observed after the initial 24 postoperative months but one. Survival curve analysis predicted a 88.2% of ten-year freedom rate from development of 4+ LAVVR after initial operation of complete AVSDs.CONCLUSION:
Postoperative LAVVR remains fairly stable following AVSDs repair. Serious deterioration is rare after 24 postoperative months, especially after the initial 48 postoperative months. But serial follow-up study with echocariogram was need till 24 postoperative months after repair of complete AVSDs.
