Abstract/OtherAbstract:
OBJECTIVESThe purpose of this study is to evaluate our initial experience with aortic valve repair using polytetraflouroethylene (PTFE) leaflet extensions in congenital valvular disease.METHODSFrom October 2008 through February 2011, 13 patients underwent aortic valvuloplasty by PTFE leaflet extensions. All valves were repaired in a tri-leaflet configuration using PTFE leaflet extensions. The median age at operation was 14 years (1.8-19.7 years) and the median weight was 58 kg (9.5-86 kg). Previous interventions included balloon valvuloplasty in two patients, aortic valvuloplasty in one and coarctation repair in one patient. Eight (73%) patients had combined aortic stenosis and insufficiency, three (23%) had isolated insufficiency and two (15%) had stenosis only. In 10 (77%) patients, a bicuspid aortic valve was present.RESULTSThe follow-up ranged from 2 to 30 months (mean follow-up 14.8 ± 9 months). At the latest echocardiography follow-up, six patients had none or trace aortic insufficiency, six patients had a mild aortic insufficiency and one patient had a mild-to-moderate insufficiency. The mean aortic insufficiency degree decreased from 1.8 ± 1.2 preoperatively to 0.8 ± 0.6 at the follow-up (P < 0.01). The mean gradient across the aortic valve decreased from 56 ± 40 mmHg preoperatively to 12 ± 13 mmHg at the follow-up (P < 0.0008). All patients are alive. There were no reoperations. The median hospital stay was 9 days (4-21 days).CONCLUSIONSThe use of PTFE leaflet extensions is an effective technique for aortic valve reconstruction in congenital valvular disease. Long-term follow-up is necessary to assess the durability of this type of repair.
