Long-term outcome after treatment of isolated pulmonary valve stenosis

摘要: Abstract Background Few data are available on very long-term follow-up after treatment for isolated pulmonary valve stenosis (PVS), either surgically or by percutaneous balloon angioplasty (PBA). Methods and results All patients with PVS were selected from our database of congenital heart defects. Their records reviewed systematically. We identified 79 treated a median 22.5 years (range 0–45 years) 139 PBA 6.0 years 0–21 years). Echocardiographic catheterization parameters indicate excellent both techniques in relieving the transpulmonary gradient. However, initial surgery 20.3% needed cardiac re-intervention: 81% severe regurgitation, but none residual stenosis. After re-intervention was 9.4% patients. In 85% indication stenosis, them although almost all developed mild regurgitation. Freedom 98.4%, 93.5%, 87.7%, 70.9% 55.7% at 5, 10, 20, 30 40 years postoperatively. group 95.1%, 87.5% 84.4% 10 20 years post-procedure. Conclusions Both safe successful acute Long-term worse than previously thought due to PR. re-interventions frequently incidence PR is high. Very still unknown.
