We sought to verify that a transannular patch on the autologous posterior wall with the common wall between the aorta and pulmonary artery can replace the conventional operation using an extracardiac conduit. Methods: From August 1997 to October 2007, 31 patients (age 15 days to 19.3 years) underwent a procedure of autologous pulmonary floor with common wall between the great arteries and transannular patch to correct a right ventricle to pulmonary artery discontinuity at our hospital. The posterior pulmonary pathways were reconstructed by direct or indirect ventriculoarterial connection using tissue in situ or donated from the dominant aorta or truncus in all cases. The aorta or truncus was tailored transversely or longitudinally to donate the inner or outer wall to the pulmonary pathway as needed. Results: There was no surgical mortality, and late noncardiac death occurred in 1 patient (3%). The postoperative systolic right ventricular to aortic pressure ratio was 0.48 ± 0.11 in the operating theater, and the central venous pressure was 9 ± 2 mm Hg. The follow-up duration was 5.5 ± 3.3 years (range, 6 months to 10.6 years). In the follow-up echocardiography, significant pulmonary stenosis (pressure gradient > 40 mm Hg) was noted in 4 patients (13%). Follow-up computerized tomograms (n = 9) showed growth of the common wall. Conclusions: The tissue deficiency of the pulmonary outflow tract could be recruited from the outer wall or inner wall of the large aorta or truncus in this disease category. We recommend such an operation to correct a right ventricle to pulmonary artery discontinuity without using an extracardiac conduit. ? 2009 The Society of Thoracic Surgeons. |
