“A technique for producing an ASD without thoracotomy or anaesthesia is presented. It can be performed rapidly in any cardiac catheterization laboratory.” (William J. Rashkind, 1966) The initial response to this report varied between admiration and horror but, in either case, Procedure stirred the imagination of the “invasive” cardiologists throughout the entire cardiology world Set stage for all future ICC procedures – the true beginning of pediatric and adult interventional cardiology.” (Charles E. Mullins, 1998) Since then it has remained an integral part of cardiac catheterisation in neonates, even after the introduction of the arterial switch procedure by Jatene and associates in 1976.

Instruments needed for BAS
•
A variety of catheters are in use for BAS. The most commonly used catheter at the present time, the 5F Miller balloon atrial septostomy catheter (Edwards Lifesciences, Irvine, CA, USA), needs an 7F introducer.
•
The low profile, dual lumen Z-5 atrioseptostomy catheter-1 (Numed, Cornwall, ON, Canada), comes in 4F or 5F sizes, depending on the balloon diameter, and requires a 5 or 6F introducer, respectively. The Z-5 catheter is advanced over a guidewire, as opposed to the Miller catheter.

Technique of Passing from FV-IVC-RA-AS-LA The procedure can be performed under sedation or GA . Access can be achieved via femoral vein. The femoral vein is punctured , an 4 or 5F introducer placed & exchanged for a 7F when the Miller catheter is used. The balloon catheter is advanced into the RA. Then the PFO is crossed and the catheter is positioned LA. Correct position is documented 2-D Echo It is useful to position / direct cath to the orifice of the LUPV The balloon is quickly inflated with 3-4 ml saline, locked, and then sharply withdrawn into the RA down to the junction – IVC Advanced in middle of RA & deflate quickly This manoeuvre may be repeated 2-3 times, size on echo The results obvious, rise in systemic arterial saturation
Balloon Atrial Septostomy • Technique of Umbilical vein approach • • • • • •
• • •
The procedure can be performed under sedation or GA . Umbilical cord is cut transversely, flush & the vein is identified, Catheter directly inserted into UV with the aid of a forceps The U V is punctured , an 4 ,5, 7F if Miller catheter is used. The progress of the catheter through the ductus venosus can be monitored 2-D echo, If resistance think DV stenosis- 0.018 wire Borne in mind that the tip of the sheath is often inside the RA and may impede withdrawal of the inflated B important remember to withdraw the sheth well into DV prior to performing the septostomy. The balloon is quickly inflated, locked, and pull into the RA down .Advanced in middle of RA & deflate quickly This manoeuvre may be repeated 2-3 times, measure on echo The efficacy from the rise in systemic arterial saturation

Potential Complications CCC •Potential Complications of Cardiac Catheterisation Most emergencies can be dealt with by interventionists in the catheter Lab Need to have rescue equipment available Support from the team Without Complication, learning curve? Even the well known-start with embolisation / failure!
Complications / Emergencies
Emergencies in the during intervention are, Vascular include injury, haematoma, bleeding
( Femoral V/ Artery / IVC / Hepatic / Ductus V Malposition of the BS, Perf / avulsion of AV Val
Injury to PV/tear in the sup aspect of the LA PV
Arrhythmias / usually respond to CPM / Drugs
Cardiac Perf – emergency Pericardiocenteses
Clots / NEC / Hypotension/ Infection / death

CONCLUSION • Although the arterial switch operation for TGA is typically performed within days after birth, and a L-R shunt through an open PDA can be maintained with PG E. • Creation of an additional shunt at the atrial level is easy to achieve, provides stable Saturation and can be recommended. • The learning curve of the operator and the team contribution is the most important for excellent results. • 2-D Echo assisted BAS minimizes risk of complications • No exposure to ionizing radiation for baby and operators • Complications continue to be associated in CHD Catheterization • Little disturbance for the baby & stay in the incubator
CONCLUSION Complication of Interventional Cardiac catheter • Complications continue to be associated in CHD Catheterisation • Efforts should be directed to improving equipment flexibility and size, and finding alternative methods for vascular access. • Patient age and weight are risk factors – M & M • The complication burden change as we push on to deal with smaller and smaller babies? • Many are avoidable with care and a meticulous approach, availability of all new technology and equipment's • Stocks of all life saving equipment's in cath Lab
