[Gianturco-Grifka device in the percutaneous closure of patent ductus arteriosus].
We present our early experience with the Gianturco-Grifka device for transcatheter closure of patent ductus arteriosus. Grifka occlusion was attempted in 13 patients (7 female, 6 male), median patient age was 6.5 years. Echocardiographic evaluation showed a mean ductal diameter of 5.47 +/- 1.09 mm, and the morphology was type C in 7 patients, type A in 5 and type E in 1 patient. The angiographic ductal morphology was 6 type A, 5 type C and 2 type E. Mean PDA diameter was 5.69 +/- 1.15 mm. Three patients had pulmonary hypertension. They were given supplemental oxygen (100%), decreasing their pulmonary pressures. A total of 13 devices were implanted, 5 of 7 mm and 8 of 9 mm. Twelve patients had complete ductal occlusion documented by aortic angiography (92%), one patient presented residual shunt (8%). Color echocardiography at 24 hrs documented complete occlusion in 12 cases. One device embolized to the descending aorta 2 hours after closure, and it was successfully retrieved in the catheterization lab. We conclude that the Gianturco-Grifka device is an appropriate alternative for transcatheter closure of the PDA. This technique can be performed in ductus arteriosus type C, D and E, with diameter < 9 mm. More clinical trials are needed to establish the long-term results of this technique.
