Este protocolo se aplica a pacientes com comunicação interventricular que desenvolveram hipertensão arterial pulmonar (HAP) com resistência vascular pulmonar (RVP) de 5 Unidades Wood ou superior, mas que ainda demonstram shunt significativo da esquerda para a direita (Qp:Qs >1,5). A fisiologia de Eisenmenger está ausente e não há dessaturação ao esforço.
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.
