Access to the native atria following conduit total cavopulmonary anastomosis.

Objectives: We describe the use of trans-thoracic and trans-conduit puncture to access the atria and perform interventional procedures in patients who have undergone conduit total cavopulmonary anastomosis.

Background: Catheter access to the atria following intra or extra-cardiac Fontan is desirable when there is a need for trans-atrial interventions.

Methods: Between 2009 and 2014, 5 patients ages 7 to 28 years underwent this approach; three trans-thoracic and 2 trans-conduit punctures.
