Four operative cases of aortic valvuloplasty with leaflet extension technique using glutaraldehyde preserved tautologous pericardium are described. All patients had severe aortic regurgitation on preoperative echocardiogram, and Grade W AR on oath-angiogram. The causes of aortic regurgitation were rheumatic fever in 2 cases, degenerative change in 1 case, and 1 case of unknown cause. The autologous pericardium was fixed In a 0.625% glutaraldehyde solution for 15 minutes and rinsed in saline for an additional 15 minutes. Leaflet extension technique varied in 4 patients depending on the site and the extent of the leaflet size and lesion. There was no hospital mortality and no thromboembolic episode without anticoagulation. Post-operative cardiac size was reduced on simple chest film in all cases, and LVESD and LVEDD were reduced on folio w- up echo cardi o gram . This experience permits us to conclude that leaflet extension technique is simple and safe in valve r construction, allowing repair of aortic valves that need to be replaced.
