PVS, usually due to dome-shaped valve apparatus, resulting from commissural fusion, comprises approximately 10% of all congenital heart diseases1–3 including 10–15% dysplastic valves,4–6 which are due to markedly thickened immobile cusps with variably reduced mobility. In moderate-to-severe valvular pulmonary stenosis (PS), subvalvular hypertrophy can cause infundibular narrowing and obstructive hemodynamics, which regresses after correction of valvular stenosis.7–9 Similarly, cyanosis can occur with right-to-left atrial shunting through a patent foramen ovale due to severe PS and decreased right ventricular chamber compliance.
Kan et al.10 introduced PBV in 1982, and since then this has become the treatment of choice for both children and adults. The short and long-term results of PBV are excellent and comparable to surgery.6,11–14 However, data from our country is scarce, therefore, we conducted a prospective study to determine the feasibility as well as the non-invasive intermediate-term follow-up results of PBV of isolated congenital pulmonary valve stenosis.
