Transcatheter ASD closure in a patient with Dextroversion: A case report

Author(s): Yasmin Abdelrazek Ali, AlaaMahmoud Roushdy, KhaledAhmed Shams, Noha Mohamed Gamal

Background: Cardiac dextroversion is location of the heart in the right chest with the left ventricle remaining in the normal position to the left but lying anterior to the right ventricle. To the best of our knowledge no specific technique has been described before for successful transcatheter secundum atrial septal defect closure in patients with dextroversion.

Case presentation: We present a case of secundum atrial ASD in a patient with dextroversion, situssolitus, AV concordance and VA concordance. Patient was referred for transcatheter closure of ASD. Her transthoracic echocardiography showed a 7 mm secundum ASD, Upper normal RV size, small restrictive VSD 2 mm and a dilated main pulmonary artery. Transesophagealechocardiography showed an 11 mm defect with abnormal orientation of inter atrial septum due to cardiac dextroversion. Usual technique for positioning of ASD Amplatzer device (ASO 11) failed with prolapsing of the device into right atrium. Failed right upper pulmonary vein technique. With successful positioning of the device across the interatrial septum using left upper pulmonary vein technique.

Conclusion: We recommend left upper pulmonary vein technique for safe and direct positioning of ASD device across interatrial septum in patients with dextroversion.
