No patch technique for complete atrioventricular canal repair
eComment: I read with great interest the innovative technique of Aramendi et al. [1] to repair complete atrioventricular canal defect. Modifications of ‘No-patch’ techniques have been sporadically attempted by some surgeons; but, since these studies usually included a limited number of patients, it is not possible today to draw definite conclusions about its long-term durability. I totally agree with the authors that this technique can be used in most of the patients and offers significant advantages. However, as the authors stated in the article, the main concern is the risk for the development of tension-related complications. This is especially true for patients with a large ventricular component. In such patients, tearing is a possible complication; but, more importantly, the absence of a patch material under valvular tissue may be also associated with a risk of postoperative left ventricular outflow tract (LVOT) obstruction. Therefore, it would be more helpful if the authors gave us information about the incidence of postoperative LVOT obstruction.
