Percutaneous transaortic occlusion of XXXX using a new versatile angiographic and delivery catheter.

@entity1 @entity2461
We evaluated the usefulness of @entity2461 ( @entity2461 ) occlusion using a new catheter that combines good angiographic properties, easy manipulation across the duct, documentation of aortic and pulmonary artery pressure, and coil delivery for percutaneous transaortic ductal occlusion. Thirty @entity1 (13 females and 17 males) who met the clinical and echocardiographic criteria for the percutaneous closure of @entity2461 were catheterized. The @entity1 selected for this study had a small to moderate @entity2461 with a conal or tubular shape, adequate aortic ampula, and normal or mildly elevated pulmonary artery pressure. The median age was 4.8 years (range, 10 months-20 years). @entity1 were catheterized by the transaortic approach using the new angiographic and coil delivery catheter specially designed for this procedure. A @entity2461 was closed in every case. A single DuctOcclud pfm coil was delivered in 28 @entity1 , and 2 @entity1 had NitOcclud pfm coils for ductal occlusion. The screening time was measured and found to be 50% less than the measured screening time using other catheters in our laboratory. Only one catheter and one guidewire were used per procedure, with no need for exchange wires or the establishment of an arteriovenous loop. The procedure time was also reduced by 50%. A minimal residual shunt, demonstrated by color-flow Doppler mapping, was present in 2 @entity1 . The new combined angiographic and coil delivery catheter is most suitable for transaortic @entity2461 coil occlusion, significantly decreasing the procedure and screening time.
