Indication
The presence of the heart defect represents the indication for an intervention/operation. The timing of the procedure depends on the:
- stage of development of the native pulmonary artery vessel bed (really pulmonary arteries)
- size of the right ventricle (inlet, muscular, outlet components?, tricuspid valve ring)
- presence of right-ventricular-dependent myocardial perfusion with proximal coronary stenoses (sinusoids).
