Echocardiography guided bed side balloon atrial septostomy in dextro transposed great arteries (dTGA) with intact ventricular septum (IVS): A resource limited country experience

Abstract

Objective: To determine effectiveness and safety of echocardiography guided bed side Balloon Atrial Septostomy (BAS) in dextro transposition of great Arteries (dTGA) with intact ventricular septum (IVS) at a public sector tertiary care hospital Karachi, Pakistan.

Methods: This case series include 40 patients with echocardiographic findings of dTGA with IVS and restricted PFO (? 2mm) who underwent bedside BAS at department of pediatric cardiology NICVD, Karachi, Pakistan. We recorded pre and post BAS diameter of PFO/Atrial Septal Defect (ASD), oxygen saturation (SpO2 %), and post procedure complications and outcome.

Results: Median age was 16 days, Majority of them (n=23, 58%) were severely cyanosed with SpO2 of 41.4
