To evaluate the feasibility, safety, and therapeutic efficacy of closing perimembranous ventricular septal defects using a transvenous Bard Rashkind double umbrella device.
Descriptive study evaluating 13 symptomatic infants, children, and adolescents (aged 3 weeks to 16 years, weight 1.8–46 kg) with perimembranous ventricular septal defects ≤ 8 mm at a tertiary referral centre.
Placement of a modified Rashkind ductal double umbrella was executed via a long transvenous sheath under transoesophageal echocardiographic guidance.
Successful partial or complete defect closure was achieved in 10 out of 13 patients (76.9%).
Placement failed in 3 out of 13 patients, with two failures due to defects exceeding device diameter and one requiring surgical retrieval after deployment in the left ventricular outflow tract.
Procedures were technically challenging with a mean procedure duration exceeding 120 minutes.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Descriptive study demonstrates defect closure in 10 of 13 pediatric patients, indicating umbrella catheterization is feasible but not suitable for routine use.
