Dissected aortic sinuses repaired with gelatin-resorcin-formaldehyde (GRF) glue are not stable on follow up


, : Dissected aortic sinuses repaired with gelatin-resorcin-formaldehyde (GRF) glue are not stable on follow up. Journal of Heart Valve Disease 11(2): 249-257

The chemical glue, gelatin, resorcin and formaldehyde (GRF) is widely used to obliterate the false lumen of acute dissected aortic wall tissue. A retrospective review of 41 consecutive patients operated upon for ascending aortic dissection between 1993 and 2000 was conducted. This study focused on 19 patients with acute aortic dissection in whom the aortic valve was resuspended and GRF glue used in the proximal aortic sinuses. These patients were compared with ascending aortic dissection patients in whom the aortic valve was not resuspended. In total, nine acute and 13 chronic dissections were performed in which aortic valve replacement, valve-sparing root reconstruction (without GRF glue), or no aortic valve surgery was carried out. The operative mortality for ascending aortic dissections was 24.4%; identified risk factors included the specific surgeon involved. Third-degree heart block occurred only in patients in whom GRF glue was used in the proximal aortic sinus (15% incidence). Operative survivors in whom the aortic valve was resuspended and GRF glue used in the proximal aortic sinus, had a 64% incidence of late recurrent aortic regurgitation requiring reoperation due to recurrent aortic sinus aneurysm formation with or without recurrent proximal aortic dissection. No recurrence of aortic regurgitation or proximal disease occurred in the other two groups (p <0.01). Actuarial survival of patients in whom the aortic valve was resuspended with GRF glue was 52.1+/-11.6% at five years and 27.8+/-14.3% at eight years, compared with 55.6+/-16.6% at five years if the aortic valve was not resuspended using GRF glue. The use of GRF glue to repair acute dissected aortic sinuses combined with the resuspension of the aortic valve is associated with an unacceptable incidence of failure of aortic valve repair and recurrence of aortic regurgitation. It may be more appropriate to resect all acute dissected aortic sinus tissue.
