2006年10月24日 · The patent ductus arteriosus (PDA) is a vascular structure that connects the proximal descending aorta to the roof of the main pulmonary artery near the origin of the left branch pulmonary artery. This essential fetal structure normally closes spontaneously after birth. After the first few weeks of life, persistence of ductal patency is abnormal.

Persistent Patent ductus arteriosus (PDA) is a common finding in extremely low gestational age newborn infants and its prevalence is inversely proportional to the gestational age. The presence of a persistent PDA is associated with increased ...

Percutaneous occlusion under fluoroscopy guidance has become the preferred method for the treatment of patent ductus arteriosus (PDA). To avoid radiation exposure and contrast agent use, PDA occlusion under transthoracic echocardiography (TTE) ...

Patent ductus arteriosus (PDA) is part of the typical morbidity profile of the preterm infant, with a high incidence of 80–90% in extremely low birth weight infants born before 26 weeks of gestation.

For detecting PDA in adults, TEE was highly sensitive and specific. The sensitivity of TEE in detecting PDA was significantly higher than that of TTE (97.5% vs 42.5%, p<0.001; or 97.5% vs 70%, p<0.01). The specificity of TTE in establishing …

2020年5月24日 · We show that percutaneous closure of PDA using only by transthoracic echocardiography TTE without radiation and contrast agents is a safe procedure. This method has wide applications in pediatric patients.

To compare the accuracy of transesophageal echocardiography (TEE) with that of transthoracic echocardiography (TTE) in the detection of patent ductus arteriosus (PDA) in the adolescent and the adult, 40 patients with PDA and 50 patients with other congenital heart diseases were studied.

In pediatric patients, transthoracic echocardiography (TTE) provides excellent images for PDA and may replace fluoroscopy as an imaging tool to guide PDA closure. Purpose: The goal was to study the feasibility of device closure under TTE guidance in patients who …

2020年10月3日 · Background: Percutaneous occlusion under fluoroscopy guidance has become the preferred method for the treatment of patent ductus arteriosus (PDA). To avoid radiation exposure and contrast agent use, PDA occlusion under transthoracic echocardiography (TTE) guidance was conducted.

2013年4月19日 · Visualization of the ductus and dimen-sions obtained by TEE and transthoracic echocardiography (TTE) were compared. Results: Complete PDA occlusion was achieved in 79/80 cases. TEE was consistently superior to TTE for PDA visuali-zation and the latter showed higher values for ductal dimensions when compared to the former.
