Total correction of tetralogy of Fallot. How to deal with the complicated ascending aorta-right pulmonary artery anastomosis
MA Ergin and RB Griepp
Ascending aorta-right pulmonary artery anastomosis may be complicated by
deformity at the anastomotic site leading to discontinuity between
pulmonary artery branches. Simple closure of such shunts through the
ascending aorta is associated with residual stenosis and pressure
gradients. An alternative approach which allows reconstruction of the
entire intrapericardial pulmonary arterial system at the initial corrective
operation is described. The transection of the ascending aorta facilitates
the exposure necessary for this extensive repair. Two illustrative cases
are presented.
