Tachyarrhythmias after the Norwood procedure: relationship and effect of vasoactive agents.
Tachyarrhythmias are common after the Norwood stage I palliation. The effects of vasoactive medications on the development of post-operative tachyarrhythmias have not been studied. The primary objective was to identify associations between postoperative tachyarrhythmias and vasoactive medication usage after Norwood stage 1 palliation. ⋯ Postoperative tachyarrhythmias are common after the Norwood procedure and are associated with longer ICU and hospital stays. High doses of milrinone, longer duration of epinephrine treatment, and the right ventricle to pulmonary artery shunt were associated with for the development of tachyarrhythmias. Further studies are required to determine the effects of anatomy on post-operative tachyarrhythmias.
