This study reviewed the short-term outcome of transcatheter closure of the defects within the oval fossa using an Amplatzer® Septal Occluder. From January 1997 to December 2000, 210 patients with defects within the oval fossa underwent successful transcatheter closure. We reviewed a total of 190 patients with left-to-right shunts, assessing the patients for possible complications and the presence of residual shunts using transthoracic echocardiogram at 24 h, 1 month, 3 months and one year. Their median age was 10 years, with a range from 2 to 64 years, and their median weight was 23.9 kg, with a range from 8.9 to 79 kg. In 5 patients, a patent arterial duct was closed, and in 2 pulmonary balloon valvoplasty performed, at the same sitting. The median size of the Amplatzer® device used was 20 mm, with a range from 9 to 36 mm. The median times for the procedure and fluoroscopy were 95 min, with a range from 30 to 210 min, and 18.4 min, with a range from 5 to 144 min, respectively. Mean follow-up was 20.8 ± 12.4 months. Complete occlusion was obtained in 168 of 190 (88%) patients at 24 h, 128 of 133 (96.2%) at 3 months, and 103 of 104 (99%) at one year. Complications occurred in 4 (2.1%) patients. In one, the device became detached, in the second the device embolized into the right ventricular outflow tract, the lower end of the device straddled in the third, and the final patient had significant bleeding from the site of venupuncture. There were no major complications noted on follow-up. We conclude that transcatheter closure of defects within the oval fossa using the Amplatzer® Septal Occluder is safe and effective. Long-term follow-up is required, nonetheless, before it is recommended as a standard procedure.

A series of five patients with complex cyanotic congenital cardiac malformations underwent surgical reconstruction of the right ventricular outflow tract using a Dacron conduit with a porcine aortic valve. All patients survived and all have shown clinical improvement. At cardiac catheterization postoperatively, a pressure gradient of between 20 and 50 mm Hg across the conduit was found in all patients. This surgical approach to patients necessitating reconstruction of the right ventricular outflow tract is effective and appears to have the best long-term results.

Abstract OBJECTIVES: The objective of this study was to evaluate our late outcomes using expanded polytetrafluoroethylene (ePTFE) valved patches with bulging sinuses and a fan-shaped valve for right ventricular outflow tract (RVOT) reconstruction. METHODS: Six hundred and ninety patients underwent RVOT reconstruction using fan-shaped ePTFE valves and ePTFE valved patches with a bulging sinus. The patients’ median age and weight were 1.3 years [range 4 days–64.2 years, interquartile range (IQR) 0.9–2.3 years] and 8.7 (range 2.8–83.1, IQR 7.4–10.5) kg, respectively. The patches were monocuspid in 634 patients, bicuspid in 49 patients and tricuspid in 7 patients. Preoperative and postoperative data were collected retrospectively from the patients’ medical records. The longest follow-up period was 17.5 (7.6 ± 3.9) years. RESULTS: There were no deaths related to the ePTFE patch. Pulmonary insufficiency was less than mild in 77.3%, and the peak RVOT gradient was <36 mmHg in 92.3% at the latest follow-up. Redo of RVOT reconstruction was performed in 40 patients, in no cases because of patch infection. Overall freedom from reoperation at 5, 10 and 15 years was 96.5%, 93.1% and 87.9%, respectively; by patient age, the rates at 5, 10 and 15 years for those younger than 1 year were 93.2%, 91.0% and 88.9%, respectively, while for those 1 year or older, they were 97.9%, 94.0% and 88.3%, respectively. CONCLUSIONS: Satisfactory long-term outcomes were achieved with ePTFE patches with a bulging sinus and a fan-shaped valve. This ePTFE valved patch could be the optimal choice for RVOT reconstruction.
