Abstract
Objective
Tricuspid atresia with normally related great vessels (TA) is considered the optimal
substrate for the Fontan pathway. The factors associated with death or transplantation
after cavopulmonary shunt (CPS) are underappreciated. We aimed to determine factors
associated with CPS–Fontan interstage death/transplantation versus transition to Fontan
in TA.
Methods
A total of 417 infants younger than 3 months of age with TA were enrolled (January
1999 to February 2020) from 40 institutions into the Congenital Heart Surgeons' Society
TA cohort. Parametric competing risk methodology was used to determine factors associated
with the competing end points of death/transplantation without Fontan completion,
and transition to Fontan.
Results
CPS was performed in 382 patients with TA; of those, 5% died or underwent transplantation
without transition to Fontan and 91% transitioned to Fontan by 5 years after CPS.
Prenatal diagnosis (hazard ratio [HR], 0.74; P < .001) and pulmonary artery band (PAB) at CPS (HR, 0.50; P < .001) were negatively associated with Fontan completion. Preoperative moderate
or greater mitral valve regurgitation (HR, 3.0; P < .001), concomitant mitral valve repair (HR, 11.0; P < .001), PAB at CPS (HR, 3.0; P < .001), postoperative superior vena cava interventions (HR, 9.0; P < .001), and CPS takedown (HR, 40.0; P < .001) were associated with death/transplantation.
Conclusions
The mortality rate after CPS in patients with TA is notable. Those with preoperative
mitral valve regurgitation remain a high-risk group. PAB at the time of CPS being
associated with both increased risk of death and decreased Fontan completion may represent
a deleterious effect of antegrade pulmonary blood flow in the CPS circulation.

- Commentary: Will the next improvement in the care of single ventricle patients come from focusing on patient selection for the cavopulmonary shunt?The Journal of Thoracic and Cardiovascular SurgeryVol. 163Issue 2
- PreviewTo paraphrase Winston Churchill, although the cavopulmonary shunt (CPS) has issues, it is the best option we have. In 1977, Choussat and colleagues delineated the renowned 10 selection criteria for the Fontan procedure. These guidelines have been revised over the years, with improvements in the assessment and management of patients with single ventricle physiology.1 More recently, advances have concentrated on early infant care before the CPS.2 The period between CPS and Fontan has been relatively overlooked, however.

- PreviewIn the current issue of the Journal, Callahan and colleagues1 report their study of infants born with tricuspid atresia and normally related great arteries from the Congenital Heart Surgeons Society (CHSS) cohort. They focused on outcomes following cavopulmonary shunt (CPS) and examined factors associated with Fontan completion, death, or transplantation following CPS. They found that by 5 years after CPS, 5% of the patients died or underwent transplantation and 91% transitioned to Fontan. They determined that preoperative moderate or greater mitral regurgitation, concomitant mitral repair, a pulmonary artery band (PAB) at CPS, and postoperative superior vena cava interventions, including CPS takedown, were associated with death or transplantation.
