Key Points

Investigate postmortem anatomical and pathological findings in infants following Jatene's arterial switch procedure for transposition of the great arteries and double outlet right ventricle.
Examined 5 postmortem hearts from a series of 11 infants (aged 2 to 17 months, mean 10.6 months) operated on between November 1976 and October 1980 in Salvador, Brazil.
Evaluated septal defects, vascular stumps, anastomoses, and the geometry and patency of reimplanted coronary artery ostia.
Coronary ostial compromise occurred in multiple specimens, including partial left coronary ostium occlusion in 3 cases, partial right ostium occlusion in 1 case, and complete left coronary occlusion due to torsion and folding in 1 case.
Coronary ostial displacement ranged from 5 to 13 mm (average 8.5 mm) for the right coronary artery and 5 to 7 mm (average 6.5 mm) for the left coronary artery.
Vascular reconstruction challenges included shortened aortic stumps in 3 cases (1 requiring a Dacron conduit), shortened pulmonary stumps in 3 cases, and anastomotic retraction from caliber disproportion in 2 cases.

Structured PICO

P

Population

5 post-mortem hearts from patients aged 2 to 17 months (average 10.6 months), 3 females and 2 males, who died during or immediately after the Jatene procedure for transposition of the great arteries (n=4) or Taussig-Bing double outlet right ventricle (n=1).

I

Intervention

Jatene's procedure (arterial switch with coronary reimplantation)

O

Outcome

Anatomo-pathological findings of the heart post-mortem, specifically focusing on septa, subpulmonary/subaortic areas, valves, arterial stumps, calibers, and coronary artery ostia displacement/occlusion

Limitations

Small sample size (5 cases)
Only evaluates the immediate postoperative period

Implication

Post-mortem analysis of early deaths following the Jatene procedure highlights that disproportionate arterial calibers and coronary ostial displacement frequently lead to fatal coronary occlusion or anastomotic retraction.
