Balloon angioplasty for aortic recoarctation: Results of Valvuloplasty and Angioplasty of Congenital Anomalies Registry

Balloon Angioplasty of Native Coarctation and Comparison of Patients Younger and Older Than 3 Months

“…[2][3][4][5][6][7]11,12 In our study, the initial success rate in group A was 76%, which is similar to Western data. There was no difference in anatomy or technique associated with the failure of dilation.…”

Magnetic Resonance Imaging Predictors of Coarctation Severity

“…A pressure gradient Ͼ20 mm Hg by catheterization has been proposed in numerous studies as an indication for surgical or balloon dilation of CoA and for the definition of procedural success. [1][2][3][4]6,7,27,28 The limitations inherent to relying on only one measurement of CoA severity, however, are recognized. .…”

“…Cardiac catheterization with angiography and hemodynamic evaluation is considered the reference standard, and many published reports regard a transcatheter peak-to-peak pressure gradient Ն20 mm Hg as an important criterion for the diagnosis of hemodynamically significant CoA in the setting of normal cardiac index. [1][2][3][4][5][6][7][8] Several noninvasive methods have been used to assess the severity of CoA. Arm-to-leg blood pressure difference measured by sphygmomanometry can provide helpful information, but several reports have shown that it may not accurately represent the hemodynamic severity of the stenosis.…”

Pediatric Therapeutic Cardiac Catheterization

“…189 -193 In a multicenter study of 200 patients with balloon dilation of recoarctation, an effective reduction in pressure gradient was seen. 37 The multicenter study demonstrated relief of recoarctation in approximately 78% of patients who underwent the procedure. Five patients died; two of the deaths (1%) were related to the procedure itself.…”
