Abstrakt: Outcome data for neonates with critical pulmonary stenosis (PS) is limited. We aimed to review the outcomes after balloon pulmonary valvuloplasty (BPV) for neonates with critical PS at our institution. All neonates with critical PS who underwent BPV from 1990 to 2017 were included. A total of 44 neonates underwent BPV for critical PS. Nonright ventricular dependent coronary artery fistulas was seen in 6/44 (13.6%) patients. Tricuspid valve z-scores were -1.9 (interquartile range [IQR] -3.04, -0.48) in those with coronary artery fistulas as compared with -0.27 (IQR -0.5, 0.8) in those without (p = 0.03). Fifteen of forty-four subjects (34.1%) patients underwent reintervention with 10 patients (22.7%) requiring an alternate source of pulmonary blood flow (3 patients subsequently underwent right ventricular overhaul, 2 underwent Glenn operations, and 1 underwent repeat BPV). Five patients underwent reintervention for right ventricular outflow tract obstruction. Pulmonary valve annulus z-score was significantly smaller in those who needed reintervention -2.4 (IQR -2.9 to -0.95) versus -0.59 (IQR -1.3, -0.15); p = 0.02. At a median follow-up of 8.2 (IQR 3.4 to 13.1) years, moderate or severe pulmonary regurgitation was seen in 22/42 (53.7 %) patients with biventricular circulation, 3 requiring pulmonary valve repair/replacement. In conclusion, coronary artery fistulas occur in a significant number of patients with critical pulmonary stenosis, occurring more frequently in patients with small tricuspid valves. Reintervention is required for 1/3 of patients. Patients with small pulmonary valve annuli are more likely to undergo reintervention for right ventricular outflow tract obstruction. Significant pulmonary regurgitation is common and may require eventual pulmonary valve replacement.
