Autologous right atrial patch for closure of XXXX .

@entity1 @entity712 @entity338 @entity2224 @entity119 @entity118
BACKGROUND: Prosthetic or pericardial patches used for the closure of @entity118 are associated with infrequent but definite problems. As an alternative, we used a right atrial free-wall patch in 12 @entity1 , 7-54 years of age. METHODS AND RESULTS: The presence of a large secundum @entity118 (n=2). associated mitral @entity338 (n=7), primum @entity119 (n=1) necessitated the use of a patch. The mitral valve was repaired in 9 @entity1 (including 2 with a primum defect). One @entity1 with a primum defect who was in congestive @entity712 preoperatively died after 3 weeks due to refractory @entity2224 . The remaining @entity1 were discharged 5 to 7 days post procedure. No flow was detected across the septal patch on predischarge echocardiography. One @entity1 underwent reoperation for failed mitral valve repair one month postprocedure. At reoperation, the patch was found to be intact with normal texture and without any suture dehiscence. Histopathological examination of the explanted patch revealed viable endothellum and subendothelial muscle on both surfaces of the patch. Follow-up ranged from 6 to 36 months. Echocardiography performed after 6 to 32 months post procedure showed an intact patch with no residual defect. All the @entity1 are in sinus rhythm. Holter monitoring performed in 6 @entity1 was normal in all of them. Electrophysiological study was performed in 2 @entity1 using a mapping catheter 4 and 6 months post-procedure, respectively, and recorded normal atrial potentials from the site of the patch. CONCLUSIONS: The use of an autologous free right atrial wall as a patch for @entity118 closure is a viable option.
