This study was retrospective case series controlled study. It included 30 patients who were referred to Tanta University hospital with the diagnosis of PDA for comparing the clinical and echocardiographic data before and after transcatheter closure of PDA with occluder device from September 2012 to August 2013. All patients parents gave their written informed consent. Included in the study 8 males (26.7%) and 22 females (72.3%) with PDA, with a mean age of 5.26 ± 3.84 years (range 7 months to 12 years) and with sinus rhythm. The weight of the patients ranged from 7 to 25 Kg with a mean of 16.03 ± 5.99, the height of the patients ranged from 40 to 106 cm with a mean 82.2 ± 22.1, the body surface area (BSA) of the patients ranged from 0.5 to 1.5 with a mean of 0.84 ± 0.26. While patients with Coexisting congenital cardiac defects that may need heart surgery, age less than 6 months, body weight less than 6 Kg, Irregular rhythm, systemic infections or endocarditis, blood diseases (haemorragic or thrombtic), very large PDA (more than 10 mm pulmonary end), hypertensive PDA or small restrictive ductus arteriosus (less than 2 mm pulmonary end with no significant hemodynamic effects) were excluded from the study.
IntroductionIn full-term newborns, DA routinely closes within one to five days after delivery, however it's considered abnormal if it remains patent more than three months after birth in term infants [1,2]. The physiological impact and clinical significance of PDA depend largely on its size and the underlying cardiovascular status of the patient, so patients with large PDA may develop left-sided volume overload and pulmonary hypertension at younger ages, leading to diagnosis early in life. If left untreated, PDA can foster the development of infective endarteritis, Eisenmenger syndrome, and other conditions, with an annual mortality rate of 1.8% [3][4][5]. Ductus closure is clearly indicated for any child or adult who is symptomatic from significant left-to-right shunting through PDA [3].Percutaneous closure of PDA has been performed for more than 30 years with several generations of devices and is the preferred mode of therapy worldwide, it has largely replaced surgical ligation in different age groups and become the treatment of choice at many institutions, since it is safe as well as cost-effective and offers considerable advantages over surgical ligation [6,7].The present study designed to compare clinical and echocardiographic data before and after transcatheter closure of PDA with occluder device.
AbstractObjective: To compare clinical and echocardiographic data before and after transcatheter closure of patent ductusarteriosus (PDA) with occluder device.
Methods:The study population consisted of 30 children with PDA who were subjected to history taking and clinical examination to detect symptoms and signs suggestive of significant shunting. Doppler, two-dimensional echocardiography studies with measurement of mitral inflow velocities in early and late diastole (E and A wave), early and late diastolic mi...
