Patients with complex congenital heart disease may have pulmonary artery stenoses that are either congenital or associated with scarring following surgical procedures. This study evaluates cutting balloon angioplasty for small-vessel pulmonary artery stenoses resistant to standard balloon angioplasty. Between October 1998 and December 1999, patients were enrolled in an FDA-approved compassionate-use protocol. During four catheterizations, there were seven lesions found resistant to standard balloon angioplasty (mean lesion diameter was unchanged: 1.8 mm +/- 0.8 mm to 1.9 +/- 0.8 mm). A cutting balloon was inflated twice in each of these lesions. Standard balloon angioplasty was then repeated. Final mean lesion diameter was increased significantly (1.9 mm +/- 0.8 mm to 3.8 +/- 1.3 mm; P <or= 0.01). Follow-up catheterizations performed a median of 14 months later showed only slight decrease in mean lesion diameter (3.2 +/- 1.2 mm), still significantly greater than initial mean lesion diameter (P < 0.03). In conclusion, cutting balloon angioplasty for pulmonary artery stenoses resistant to standard balloon angioplasty improves the immediate and intermediate term results of angioplasty for these lesions. |
