Initial experience with a bicuspid polytetrafluoroethylene pulmonary valve in 41 children and adults: a new option for right ventricular outflow tract reconstruction.

BACKGROUND: As the population of children with repaired congenital heart disease ages, an increasing number of patients will benefit from pulmonary valve insertion. We report our initial experience in 41 consecutive patients treated with placement of a surgically created polytetrafluoroethylene bicuspid pulmonary valve. METHODS: A bicuspid pulmonary valve with orifice size greater than 24 mm is created with polytetrafluoroethylene and sutured into the right ventricular outflow tract. To obviate the need for reoperation in growing children, this technique is limited to older children and adults. Polytetrafluoroethylene bicuspid pulmonary valves were placed in 41 patients (age: range, 5.0 to 64.7 years, median = 15.7 years; weight: range, 14.2 to 99.0 kilograms, median, 52.0 kg). All patients had pulmonary insufficiency, pulmonary stenosis, or both, after previous intervention for tetralogy of Fallot (27), pulmonary stenosis (11), pulmonary atresia with intact ventricular septum (2), or double outlet right ventricle (1). RESULTS: All patients left the operating theater with transesophageal echocardiography documenting no pulmonic stenosis and zero to trace pulmonic insufficiency. Median hospital length of stay was 5 days (range, 3 to 15 days; mean, 5.8 days). Follow-up including echocardiography ranged from 0.2 to 3.1 year (median follow-up, 1.5 years) and revealed significant improvement in New York Heart Association Classification, pulmonary insufficiency, and right ventricular end diastolic dimension. CONCLUSIONS: Polytetrafluoroethylene bicuspid pulmonary valve reconstruction of the right ventricular outflow tract is a safe, effective, and durable technique for the short term. Appropriate oversizing minimizes outflow tract obstruction while maximizing competence. Long-term follow-up is necessary to determine the true value of this technique.

The modern approach to patent ductus arteriosus treatment: complementary roles of video-assisted thoracoscopic surgery and interventional cardiology coil occlusion.

BACKGROUND: In an effort to analyze our experience and develop treatment guidelines, we reviewed all our patients with patent ductus arteriosus (PDA) treated with video-assisted thoracoscopic surgery (VATS) or interventional cardiology coil occlusion. METHODS: One hundred patients underwent 102 cardiac catheterizations. Forty-five children underwent VATS. The entire cohort of patients is 141 because 4 patients underwent both catheterization and VATS. RESULTS: Successful PDA coil occlusion occurred in 91 patients (91 of 100; 91%); 8 had unsuccessful attempts at coil occlusion and 1 was referred for surgical ligation after catheterization without any attempt at coil placement. Thirty-nine children had successful VATS PDA closure. Six children required conversion to thoracotomy because of inadequate exposure during VATS. Hospital stay for children more than 45 days of age was as follows: VATS median stay, 1 day, mean, 1.4 days; thoracotomy median stay, 4 days, mean, 4.6 days. One patient treated with PDA coil occlusion developed a recurrent PDA and required reembolization. Three children underwent initial catheterization without successful coil placement with subsequent successful VATS. All VATS patients left the operating theater with echocardiography documenting no residual PDA. Two children who underwent successful VATS with no residual PDA at hospital discharge were found on outpatient follow-up to have developed tiny recurrent PDAs and both were successfully coil occluded; 1 of these 2 children is 1 of the 3 children initially evaluated by catheterization and then referred for VATS. CONCLUSIONS: Video-assisted thoracoscopic surgery and coil occlusion represent complementary techniques for PDA treatment. A rationale for selection of the appropriate treatment modality can be based upon the size and age of the patient and the size and morphology of the PDA.
