Percutaneous transluminal pulmonary valvuloplasty may be indicated in not only isolated pulmonary valve stenosis, but also complex congenital heart diseases. Because palliative surgery for increasing pulmonary blood flow entails a risk of scar formation and immediate postoperative complications, catheter intervention is preferred, if possible. However, an acute-angled, twisted, or tortuous access route or a small valve orifice occasionally makes it difficult for the catheter to reach or cross the target. We succeeded in performing this intervention for such a complex stenosis effectively and safely in a patient with tricuspid atresia, ventricular septal defect (VSD), and severe pulmonary valve stenosis, thereby evading surgery. In previous reports, the catheter for this cardiac anomaly was accessed via the femoral vein. In the present case, the catheter was advanced through the femoral artery via the aorta, left ventricle, VSD, and right ventricle to the pulmonary valve, using a micro-catheter in a telescopic manner, in combination with a coronary balloon dilatation catheter. This maneuver, which has not been reported previously, made it much easier to perform the procedure as compared to the femoral vein approach, despite the acute turn and the pinhole orifice. Moreover, reported complications of the femoral vein approach, including bradycardia, hypotension, and valve regurgitation, were not observed in this case. We conclude that the femoral artery approach can be a safe and effective alternative in patients for whom a more conventional procedure has been unsuccessful. © 2013 Wiley Periodicals, Inc.
