[Decompensated valvular disease and coarctation. One-stage repair using a median approach with an ascending aorta-abdominal aorta shunt]

The tactical decision in patients with decompensated valvular disease associated with a severe stenosis of the aortic isthmus is always difficult. One stage surgical repair using two separate approaches is a long and high risk procedure. It would seem more logical and safer to treat the lesions in two stages a few weeks apart, the severest lesion being managed first. In the two cases reported. The isthmic stenoses and valvular lesions were of the same severity and made both classical techniques impracticable. Therefore the patients underwent a single stage procedure by a median approach associating valve replacement under cardiopulmonary bypass (mitral and tricuspid in one and aortic in the other case) and an ascending aorta-abdominal aorta dacron conduit. The present postoperative survival periods are 30 and 9 months. The functional result was good (Class 1 and 0) and postoperative angiography has shown the montage to be working satisfactorily. This technique is exceptional but may be useful in borderline cases with decompensated valvular disease and severe isthmic stenosis.
