Balloon angioplasty for postoperative recurrent coarctation of the aorta.

Surgical repair for recurrent or residual postoperative coarctation of the aorta is associated with some morbidity, mortality, and an incidence of recurrent coarctation that may be as high as 20%. Balloon angioplasty for recurrent or residual postoperative coarctation has become the standard treatment of choice for this condition. In this article, we review the protocol we use, and the acute and long-term results of this procedure. Since 1983, over 400 patients have undergone balloon angioplasty for recurrent coarctation with excellent immediate relief of the gradient and improvement in the diameter. On long-term follow-up, the majority of these patients enjoyed a lasting beneficial effect of the balloon angioplasty. We discuss the future use of stents for selected patients who are not amenable or failed balloon angioplasty of recurrent or residual postoperative coarctation.
