Abstract:
We successfully performed an anatomical repair for double outlet right ventricle associated with straddling and cleft mitral valve in two patients. In both patients position of the anterior and posterior papillary muscles was found to be normal. Therefore, all staddled mitral component was detached. The mitral valve competency was achieved by suture-closure of the cleft and annuloplasty. This procedure facilitated intraventricular re-routing from the left ventricle to the pulmonary artery. Then arterial switch was performed. Postoperative course was uneventful and no significant mitral valve regurgitation was found in either patient postoperatively. This procedure can be a good option in patients with double outlet right ventricle associated with straddling mitral valve.
