deployment of device, residual shunt was noted in one patient at 6-month echocardiographic follow-up. The num- ber of females was more than males. The overall technical success rate was 91%. The occlusion rate regardless of the type of device was 98% with a signi cant residual shunt rate of 2%. Minor and major complications were 11% and 11% respectively.
Conclusion: Transcatheter closure in children less than 6kg regardless of the device that was used is e ective and safe in the Philippine setting

Objective: This study was aimed to discuss the various techniques employed to retrieve the embolized devices during interventional cardiac catheterization procedures.
Background: Embolization of the devices may be due to many reasons varying from improper estimated size to problems with image quality just before device release. Once embolized the retrieval depends upon the type, site, size and position of the device. Additionally availability of the appropriate sheaths, variety of snares, bioptomes, bal- loons, biplane uoroscopy and lot of patience is the pre- requisite for device retrieval.
Methods: In this total 11 devices were embolized from august 2010 to October 2017.Of these 7 were ASD, 3 PDA and one of them was VSD device.
Snares, sheaths, multiple catheters, balloons and wires were used to retrieve all the devices with reasonable results. The hemodynamic data and vita signs were care- fully monitored during the procedures along with surgical back up.
All devices were removed successfully with variable time interval and uoro exposure. The smallest patient in whom device was removed was 1 year of age. Various uoro projections techniques were used to retrieve embolized devices. In certain situations balloon was in ated distal to device to change the position for favorable capture. There was no mortality or morbidity due the procedures. Patient’s rhythms remained stable and no cardiac arrest was recorded.
Conclusion: Device embolization can be prevented with accurate preprocedure assessment and thorough estima- tion of position, stability, and residual ow judgment on color with good imaging. Device retrieval is safe if all the required equipment and expertise is available.
23. TRANSCATHETER INTERVENTION IN

Background: Coarctation of Aorta is a congenital abnormal- ity which can have poor outcome without early interven- tion. Transcatheter intervention has made it the preferable modality of therapy for CoA over surgery.
Objective: To ascertain the patterns of presentation, clin- ical, echocardiographic features, modality of intervention and outcomes of coarctation of aorta patients whom pre- sented for transcathter intervention.
Methods: A retrospective analysis of patients’ records were done from 2002-2017, in a tertiary cardiac specialist centre in Sri Lanka. 50 patient were included. Successful outcome was de ned by a drop in pressure >50% or <20mmHg.
Results: Number of CoA patients n=50. Their age ranged from 8 -50 years. Mean age was 23.2 years. Males were 54%( n=27) of the populace. Majority, 54%( n=27)] had asymptomatic hypertension. Amongst those symptom- atic, shortness of breath was the commonest n=10(43.4%). Headache was seen in n=4( 17.3%). Most, n=25( 50%) had LVH on 2D-echo. All had preserved EF>60% on ini- tial workup. Eighteen (36%) had additional echo struc- tural abnormalities. Valvular abnormalities were the commonest n=13(72.2%). Bicuspid aortic valves were seen in n=4(22.2%), AR & MR were each observed in n =3 (16.6%). COA narrowest diameter was 1.5mm, and the maximum diameter was 15.4mm. Mean was 4.77mm. Eighteen(36%) underwent only balloon dilation, while n=25(50%) underwent direct stenting. The pre-proce- dural mean PG was 62.93mmHg and post- procedural PG was 11.79mmHg, the reduction was statically signi - cant (P=0.00). Assessed separately the mean PG before intervention in the balloon dilation patients were 63.88 ±
