Aortic Valvuloplasty; Leaflet extension technique with glutaraldehyde preserved autologous pericardium

Abstract
|
|
|
Four operative cases of aortic valvuloplasty with leaflet extension technique using glutaraldehyde preserved autologous pericardium are described.
All patients had severe aortic regurgitation on preoperative echocardiogram, and Grade IV AR on cath-angiogram. The causes of aortic regurgitation were rheumatic fever in 2 cases, degenerative change in l case, and l 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 anticoahulation. Post-operative cardiac size was reduced on simple chest film in all cases, and LVESD and LVEDD were reduced on follow-up echocardiogram.
This experience permits us to conclude that leaflet extension technique is simple and safe in valve reconstruction, allowing repair of aortic valves that need to be replaced.
