he coexistence of coarctation of the aorta (COA) and patent T ductus arteriosus (PDA) is well documented.1 Transcatheter treatment of COA and PDA as isolated lesions is also well reported.2 – 10 Balloon dilation of native COA has proven to be safe and efficacious in several large series, especially in children beyond infancy.2 – 6 Successful transcatheter occlusion of small to moderate size PDAs with the Gianturco coil has also been reported.7 – 10 We report a case of a pediatric patient found to have both a COA and PDA who underwent balloon dilation of the COA and coil occlusion of the PDA in a single cardiac catheterization. Review of the English literature revealed no previous reports of this combination of transcatheter interventions during a single catheterization procedure. jjj A 3 12 -year-old boy who was hospitalized with pneumonia also presented with clinical signs of a COA and a PDA which was confirmed with echocardiography. At cardiac catheterization, he was found to have a discrete preductal From the Department of Pediatric Cardiology, Texas Children’s Hospital, Baylor College of Medicine, Houston, Texas.

COA measuring 4.3 mm in diameter and a 44 mm Hg peak systolic gradient (Figure 1). The aortic isthmus diameter measured 11.0 mm. A small type C PDA, based on the criteria of Krichenko,11 with a minimum diameter of 1.5 mm just distal to the COA was visualized. Retrograde balloon dilation of the COA was carried out using a previously described technique.4 Following dilation with a 12-mm Tyshak balloon (B. Braun Medical Inc.,

G. Wesley Vick,
Bethlehem, Pennsylvania), the gradient decreased to 6 mm Hg (Figure 2). A repeat descending aortogram with a balloon angiographic catheter placed prograde (through a transseptal puncture) demonstrated marked improvement of the COA diameter with no aneurysm or extravasation of contrast noted. Without crossing the COA site, an 0.018-in PlatinumPlus exchanged guidewire (MediTech Inc., Watertown, Massachusetts) with a very soft tip was

slipped through the PDA and was retrieved while still secured in the snare. Further inspection and remeasurement of the PDA dimensions showed that the minimum ductal diameter had increased to 2.9 mm following angioplasty (Figure 3). Using the same technique, an 0.038-in gauge, 5-cm length, 5-mm diameter Gianturco coil was then implanted into the PDA and adjusted so that there was no coil protrusion into the aorta. The snare and Berenstein catheter were removed and a repeat descending aortogram demonstrated no evidence of residual shunting across the PDA. The previously dilated COA site measured 9.5 mm (Figure 4). Cephalexin (25 mg/kg) was administered and continued for 24 hours. The patient was discharged the following day with no blood pressure differential between the arms and legs. jjj Although there are case reports of transcatheter treatment of coexisting COA and PDA, the procedures were performed sequentially at different catheterizations.12 – 14 All underwent balloon dilation of the COA first, followed by PDA occlusion at a much later date. This is because of the concern of aortic dissection or aneurysm at the newly dilated coarctation site caused by further catheter or wire manipulation during the ductal occlusion procedure. The concern is legitimate and because the PDAs were all hemodynamically insignificant, the decision to delay the occlusion to allow for healing of the aorta is reasonable. The disadvantage of this strategy is one of cost and inconvenience of an additional cardiac catheterization. Recognizing the potential for dissection in the newly dilated COA site in our patient, coil occlusion of the PDA was carried out with extreme care only after we recognized that passage of a catheter into the more distally located ductus could be accomplished without traversing the dilated COA site. The coil delivery catheter was advanced into the MPA with the aid of a guidewire with a very soft tip. The wire

In conclusion, we report the case of a patient with COA and PDA who underwent cardiac catheterization and successful balloon dilation of a COA and coil occlusion of a PDA during a single procedure.

was advanced with extreme caution such that the soft tip did not distort and there was no resistance during its advancement. The original coil selected was based on the minimum diameter of the PDA as measured on the predilated angiogram. We followed the reported recommendation of using a coil with a helical diameter twice the minimum diameter of the PDA.7,8 The PDA dimensions increased following COA dilation. The first coil slipped into the MPA during delivery but was easily retrieved while still secured in the snare (Figure 3). A repeat angiogram demonstrated the PDA minimum diameter had almost doubled and a larger coil was used. Consistent with a type C ductal configuration, there was little to no aortic ampulla in which to seat the distal coil loops and the snare technique was useful in adjusting the coil position to minimize any protrusion into the aortic flow. While we demonstrate this combination of procedures to be
feasible, several important points are highlighted. First, because of the potential for aneurysm formation or dissection of the aortic wall, we emphasize the importance of not crossing the freshly dilated COA site. This combined procedure was only possible because the PDA was located distal to the COA and could be approached without traversing the COA site. The transseptal approach to reach the proximal descending aorta for follow-up angiograms and simultaneous blood pressures recordings above and below the COA site also avoids further trauma to the dilated site. Second, passage of a catheter into the MPA for PDA occlusion should be performed initially with a guidewire with a very soft tip and the wire should be advanced with extreme caution. Third, it is important to remeasure the PDA minimum diameter following balloon angioplasty of the COA since the PDA dimension may change, as demonstrated in our case.
