Why the study?

Does stent implantation improve hemodynamics and vessel diameter in patients with pulmonary artery stenosis?

Structured PICO

Does stent implantation improve hemodynamics and vessel diameter in patients with pulmonary artery stenosis?

Population

37 patients with pulmonary artery stenosis (PAS), median age 7.0 years (range 0.8-31.4 years), median weight 20.5 kg (range 7.4-85 kg). 22 patients had previous tetralogy of Fallot repair.

Intervention

Stent implantation (55 stents implanted in 36 patients)

Outcome

Immediate and short-term hemodynamic and anatomic results (peak systolic gradient across the stenotic segment, diameter of the narrowest segment, and right ventricular-to-aortic mean systolic pressure ratio)surrogate

Stent implantation is effective in immediately reducing the peak systolic gradient and increasing vessel diameter in patients with pulmonary artery stenosis, though significant procedural complications can occur.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

May support acute gradient reduction with stenting in pulmonary artery stenosis; hypothesis-generating, should not change practice.
