OBJECTIVES: Certain congenital heart defects require the creation of an unrestrictive atrial septal defect (ASD) to relieve atrial hypertension, to maintain systemic cardiac output, or to achieve adequate atrial mixing to improve systemic oxygen saturation. We describe a series of patients, ranging in age from 5 weeks to 17 months, in whom we implanted a stent across the atrial septum to create a lasting, unrestrictive interatrial communication. METHODS: Five patients with left heart obstructive defects presented with severe left atrial hypertension. The patients weighed 3.5-10.1 kg. Patients 1 and 2 presented at 5 and 9 weeks of age, respectively. Patient 1 had a restrictive patent foramen ovale, and patient 2 had an intact atrial septum. Patients 3, 4, and 5 had previous cardiac surgery including atrial septectomy. At presentation, all patients were poor surgical candidates. RESULTS: Using standard percutaneous technique, a premounted Palmaz-Genesis stent (Cordis Corporation) was implanted across the atrial septum in all 5 patients, using balloons ranging from 7 to 10 mm diameter. Each patient had a dramatic decrease in left atrial pressure and increased ASD diameter. All stented ASDs remained widely patent, confirmed by Doppler echocardiography, until elective surgical stent explant. CONCLUSION: Patients presenting beyond the neonatal period with left heart obstructive defects and intact atrial septum or restrictive ASD present a challenging problem. We report a safe and effective technique for relief of left atrial hypertension in infants using premounted intravascular stents. All patients had immediate marked hemodynamic improvement. |
