Key result
The Rashkind double umbrella prosthesis protruded into an arterial lumen in 47.2% of patients after patent ductus arteriosus closure, with turbulence and protrusion sometimes resolving over time.
Why the study?
Does percutaneous transvenous closure of patent ductus arteriosus with a Rashkind double umbrella prosthesis cause device protrusion and blood flow turbulence in patients with PDA?
Population
36 patients with patent ductus arteriosus, mean age 8.2 years, mean weight 25.5 kg.
Design
Cohort
Follow-up
mean 15 months (range 6-26 months)

May warrant serial imaging for spontaneous resolution after Rashkind PDA closure; leaves open long-term clinical sequelae in Level 3 data.
Observational (n=36)
Yes
Does percutaneous transvenous closure of patent ductus arteriosus with a Rashkind double umbrella prosthesis cause device protrusion and blood flow turbulence in patients with PDA?
The Rashkind double umbrella device can protrude into the descending aorta or left pulmonary artery, sometimes causing turbulence, but both protrusion and turbulence can resolve over time.
Ottenkamp et al. (1992) conducted an observational in Patent ductus arteriosus (n=36). Percutaneous transvenous closure with a Rashkind double umbrella prosthesis was evaluated on Diagnosis or exclusion of protrusion of the Rashkind device with or without turbulence of the blood flow. The Rashkind double umbrella prosthesis protruded into an arterial lumen in 47.2% of patients after patent ductus arteriosus closure, with turbulence and protrusion sometimes resolving over time.
