Aortic annulus reconstruction successfully closes aorto-left atrial fistulas with no postoperative regurgitation in two patients.
Case Report (n=2)
Closing an aorto-left atrial fistula from both the left atrium and aorta using patches and pledgets is a successful technique for repairing perivalvular leaks following the Manouguian procedure.
May support annular reconstruction for post-Manouguian fistulas; hypothesis-generating and should not yet change practice.
Successful reconstruction of the aortic annulus for perivalvular leak following combined valve replacement was performed in two patients, 6 and 7 years postoperatively, using Manouguian's operation. A fistula was seen at the junction of the aortic annulus and the superior or inferior margin of the patch used for enlargement. This fistula was closed from both sides; from the left atrium with reinforced Teflon pledgets and from the aorta using a patch. Successful reconstruction of the aortic annulus was made, and no regurgitation was seen after the operation.

Hachida et al. (1994) conducted a case report in Aorto-left atrial fistula / perivalvular leak following aortic valve replacement (n=2). Reconstruction of the aortic annulus (closure of fistula) was evaluated on Successful reconstruction and absence of regurgitation. Reconstruction of the aortic annulus to close an aorto-left atrial fistula was successful in two patients, with no regurgitation seen postoperatively.
