Transcatheter closure of patent ductus arteriosus using ADO device: retrospective study of 149 patients

Patent ductus arteriosus [PDA] is a common form of congenital heart disease and forms about 5-10% of congenital heart diseases. Surgical closure is safe and effective; however, certain patients may experience some morbidity. Recently, transcatheter closure of PDA using the Amplatzer duct occluder has been shown to be safe and efficacious. To evaluate whether transcatheter closure with this device offers an alternative to surgical closure of PDA. Between July 2006 to July 2008, 149 patients [98 females and 51 males] with PDA underwent cardiac catheterization in an attempt to close their PDA by transcatheter approach using Amplatzer duct occluder device. The patient's age ranged from 4 months to 45 years [median 5 years]. Successful PDA closure was achieved in 136 patients [91.2%] with 100% complete closure rate within 24 hours after the procedure. Thirteen patients [8.7%] had unsuccessful attempts, 11 [7.3%] of them had failure of deployment of the device, while embolization of the device occurred in two of the patients [1.3%]. Amplatzer duct occluder device is safe and effective for closure of different types and sizes of PDA with low rate of complication

Percutaneous pulmonary valvuloplasty in critical pulmonary valve stenosis

Critical plumonary valve stenosis represents an emergency and immediate treatment is mandatory. Percutaneous plumonary valvuloplasty is the treatment of choice for isolated plumonary valve stenosis. Results and complications, of this procedure in our cath. Lab. From January 2006 to August 2009, 28 neonates and infants with critical plumonary valve stenosis [mean age 33.5 days: range 6-88 days] underwent percutenous plumonary valvulopalsty. All patients were cyanosed, and the clinical diagnosis was confirmed by cross sectional and Doppler echocardiography. The plumonary valve was successfully crossed in all patients. The trasvalvular gradient dropped from 86.9+_21mmgh to 33.2+_20.9mmgh, the mean right ventricular systolic pressure dropped from 100.4-f_2o.7mmgh to 54.2+_20.9mmgh, and oxygen saturation increased from 81+_8% to 97+_2%. There were 9[32.1%] major complication including 4[14.2%] death ,3[10.7%] hemopericardium reguiring drainge and transfusion, and two[7.1%] patients developed considerable venous congesation. During a mean followup of 1.6 years, 19[86.3%] of the 22 patients remain free of important restenosis. Percutaneous plumonary valvuloplasty is effective procedure of first choice in treatment neonates and infants with critical plumonary stenosis
