Fontan fenestration closure in the catheterization laboratory--echocardiographic evaluation of residual right to left
1Michigan Congenital Heart Center, Department of Pediatrics and Communicable Diseases, University of Michigan, Ann Arbor, USA.
Abstract:
This study is a retrospective review using transthoracic echocardiography to assess the success of fenestration closure as well as residual right to left shunts in 35 patients who underwent Fontan fenestration closure in the catheterization laboratory. There is a high rate of closure of the Fontan fenestration; however, other residual right to left shunts are common.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
