Summary

Though graded balloon-atrial-septostomy (BAS) has been accepted as an effective palliative therapy for severe pulmonary arterial hypertension, spontaneous closure of septostomy is not uncommon. Radiofrequency-catheter-ablation (RFA), which has the potential to cause irreversible damage around the rim of created inter-atrial communication, might contribute to prevent the spontaneous closure. In patients with severe pulmonary arterial hypertension, the combined use of RFA and BAS (CURB) is investigated to create a stable inter-atrial communication.

Conditions

Interventions

OTHER

Radiofrequency catheter ablation

(1) In control group: only graded balloon atrial septostomy will be carried out and there is no radiofrequency catheter ablation. (2) In single-RFA group: after graded balloon atrial septostomy identical to control group, radiofrequency catheter ablation will be performed immediately around the rim of created inter-atrial fenestration. (3) In double-RFA group: the first step is radiofrequency catheter ablation on fossae ovalis; and then the other two steps are identical to the single-RFA group (BAS and RFA around the rim of fenestration).

OTHER

Balloon atrial septostomy

Graded balloon atrial septostomy is performed in all patients.
