Name: Manha, Age: 1.5 month, Wt : 3.5 Kg
VSD device closure in retrograde approach 2012
- Perimembranous VSD closed by ADO II device from retrograde approach is practiced in 100% cases of small VSD’s including DC VSD,s.
- This method was innovated by pediatric cardiac team of Armed Forces Pediatric Cardiac Center spontaneously while doing an adult female case in 2012. Named as Fatema,s technique by Little Heart
Closure of long slender PDA (2013)
Tamim , S/O Sgt Kamal, Age: 01 Yrs , 07 Kg 23 mm long
Closed with 5 x 4 mm Cook Coil
Snare assisted PDA device closure (2004)
The minimalistic approach in ASD device closure (2005)
- In minimalistic approach, we can reduce the procedure time by avoiding many steps like reducing sedation time & also reducing the radiation of the patient, operators & cath lab staffs.
- Cocktail sedation is used instead of general anesthesia.
- Transthoracic Echocardiography is used instead of Transesophageal Echo.
- Diagnostic cath is not done
- Balloon sizing is done to stop the flow
PDA device with RFV technique (2006)
Age: 2 months, Weight: 2.2kg
Dis: Large PDA with reverse shunt, Severe PHT
Device closure done with 6/6 ADO I device
Device closure of large tubular PDA ( Spl design)
Device configuration for cylindrical PDA
Aortic end of the device was pulled inside the PDA and a round shape configuration created which was pressed against the PDA wall and secured the device inside PDA. Other ends of the device released inside the pulmonary artery.

PFO closure in migraine (2013)
RVOT stenting (2006)
- Year: 2006
- Sneha, 7 mo old baby presented with severe cyanotic spell,
- Diagnosis: DORV, VSD, severe infundibular & valvular PS
- Surgeon refused to do BT shunt due to less body wt ( 3 Kg)
- Pt was taken to cath lab for life saving purpose.
ASD device closure in patient with small LA
ASD device closure in patient with floppy rims with double disc in LA

- Name: Rafi
- Age: 1 month, Weight: 3.5 kg
- Disease: Severe pulmonary valve stenosis
- Procedure: Balloon valvoplasty is done 6×3 Balloon
First ever MFO Device Closure in Bangladesh
at NNF Lab. 28.10.18
- Sanzam, 4.6 Yrs, 16 Kg
- Disease: Small PM VSD
- Device: 6 x 4 MFO Device
- No AR, VSD Flow after deployment of Device
New treatment protocol
PPHN treatment protocol (NNF Protocol) Ref:
Notes on basic paedi cardiology.
Protocol formulated by us for Persistent Pulmonary Hypertension in 2001 has success rate > 99%
First line treatment:
- High flow oxygen therapy for 72 hours
- Tab Cardopril
- Inj Frusemide
- Inj Digoxin
PPHN treatment protocol (NNF Protocol)
Second line treatment:
- Tab Sildenafil
- Some of the patients required ventilator support due to profound hypoxemia and acidosis.
- Some of the patients require ionotropic support with Dopamine and/ dobutamine.
- In preterm patients with significant PDA without right to left shunt Inj Indomethacin or Syp Ibuprofen or Paracetamol may be used to close the ductus
- Third line management: Inhaled Nitric Oxide (iNO) and ECMO if available
Use of sildenafil in children
Management protocol in cyanotic spell
(NNF protocol) Ref, Notes on Basis Ped Cardiology
- O2 inhalation
- Keep the baby calm and quiet
- Do not irritate the baby by giving IV line
- Inj. Diazepam 0.5 mg/kg PR stat
- Mother should be encouraged to sedate the baby
- Inj. Hartman solution/FFP-10 ml/kg IV stat
- Inj. Morphine 0.1 mg/kg IV or SC stat
- Inj. Esmolol 0.5 mg/kg IV in one minute
- Inj. Sodium bicarbonate 1-2 mEq/kg diluted with an equal amount of 5% DBS in 1 hour
- Artificial ventilation
- RVOT stenting in the young infant.
- BT shunt.
- PDA stenting if PDA is present.
Note: Inj Esmolol in the cyanotic spell: 0.5 mg/kg in 5 minutes. Then 50 µgm/kg/min over 4 minutes. If no response: 0.5 mg/kg over 5 min again. Then 50-200 µgm/kg/min up to 48 hours
Special Prophylaxis for Tetralogy of Fallot (TOF)
Phenobarbitone is used in the author’s center since 1998 for a severe form of infundibular stenosis to avoid hypoxic convulsion and oxygen consumption.
Collection of sweat for sweat chloride test

Medicine is the science which is evidence-based. Evidence comes out usually from the experience of the physician and surgeons. Some of the experience is achieved during managing complication from a normal procedure and bailing out from that in a safe way. Many of our new innovation in cath lab was achieved during such a bailout procedure. Medical management protocol was designed on the basis of necessity as a low resource country and the syndrome was identified on the basis of experience.
