Temporary adjustable pulmonary artery banding in ALCAPA patients with severe dysfunction (EF < 25%) accelerated the recovery of normal ejection fraction compared to no banding.
Does a temporary adjustable pulmonary artery band improve left ventricular function recovery in patients undergoing ALCAPA repair?
Temporary adjustable pulmonary artery banding may accelerate the recovery of left ventricular function in ALCAPA patients with severe dysfunction (EF < 25%) undergoing repair.
There is marked improvement of MR grade and LV function, and no mortality during a 10-year period in the group with EF > 25%. Patients with EF < 25% treated with a PAB demonstrated an improved trajectory toward EF improvement, achieving normal function earlier than those without PA band. Temporary adjustable PAB may be beneficial in ALCAPA patients with severe dysfunction.
Bibevski et al. (2026) studied this question. Temporary adjustable pulmonary artery banding in ALCAPA patients with severe dysfunction (EF < 25%) accelerated the recovery of normal ejection fraction compared to no banding.
