Ce protocole s'applique aux patients présentant une communication interventriculaire ayant développé une hypertension artérielle pulmonaire (HTAP) avec une résistance vasculaire pulmonaire (RVP) de 5 unités Wood ou plus, tout en conservant un shunt gauche-droite significatif (Qp:Qs >1,5). La physiologie d'Eisenmenger est absente et il n'y a pas de désaturation à l'effort.
In patients who have developed PAH with PVR ≥5 WU, VSD closure may be considered when there is still significant LR shunt (Qp:Qs >1.5), but careful individual decision in expert centres is required.
Surgical closure can be performed with low operative mortality (1–2%) and good long-term results.
Transcatheter closure has become an alternative, particularly in residual VSDs, in VSDs that are poorly accessible for surgical closure, and in muscular VSDs that are located centrally in the interventricular septum.
