uniformly low for all occluders in current era at experi- enced centers. The modi ed structural new designs do not show any advantages on the procedural complications on early and midterm follow-up, but long-term studies are warranted.

Patients with TOF obtain good response to surgical man- agement in the rst year of life, however in patients with low birth weight, in whom a surgical intervention could lead to poor results, we frequently choose conservative management awaiting weight gain to take then to surgical correction. Aortic coarctation (AoCo) can be a primary or secondary event and can coexist with other cardiac pathol- ogies. The symptoms can be oligoanuria, metabolic acido- sis, heart failure and nally cardiogenic shock.
Here we present two cases in which, through cardiac inter- vention, two critical pathologies can be solved in new- borns with low birth weight with satisfactory results until reaching the appropriate weight for surgical correction.

Background: The technique of transcatheter closure of PDA has evolved greatly, however data on safety and e - cacy are limited in < 3kg infants with haemodynamically signi cant ductus.
Objective: This study aimed to investigate the feasibility, safety and outcome of transcatheter closure of PDA in infants weighing < 3kg.
Methods: Patients weighing 3kg or less in whom transcath- eter PDA closure was attempted were analysed retrospec- tively to review the immediate and midterm outcomes.
Results: Fifteen patients underwent transcatheter PDA closure between July 2013 to January 2018. Three infants
had Rubella syndrome, one was operated for mal-rotation of gut, one was syndromic while four had PDA of prema- turity. The mean weight was 2.41+0.65 kg (Range 1.4 -3.0; median 2.4kg) and mean age was 55+29 days (Range: 28 -120 days ). PDA measured 3.59+1.5mm with mean Pulmonary artery(PA) pressure of 40.13+ 12.36 mm Hg and PA to Aortic pressure ratio of 0.73+ 0.14.
All procedures were done from femoral venous access under conscious sedation. No arterial access was taken. The devices used were ADO I like occluders(5/4,6/4,8/6,8/6mm) in 4 cases , AVP II(4,6,7,8,8mm) in 5 cases, ADO II Additional Size (5/4mm) in 1 case , AVP IV (6,7,7,8mm) in 4 cases and bioptome assisted Cooks coils in 1 case. Devices were deployed using 4F sheath in 4, 5F sheath in 7 and 6F Sheath in 3 cases. One case required upsizing to 7F for retrieval purpose.
Successful device implantation with complete occlusion was achieved in all cases. Device embolisation in 2 patients was successfully retrieved and upsized. The requiring aver- age uoroscopic time was 10.57+ 14.12 minutes, range (2.83 - 56.03 minutes), longer in 2 patients due to device embolisation. There was no case of device related obstruc- tion of aorta or access related vascular injury or death while one patient left PA was impinged on follow up (8mm AVP II used). Post procedural weight gain on a mean follow up of 10.07+9.4 months was 4.45+3.43 kg.
Conclusions: Transcatheter closure of haemodynamically signi cant PDA in infants weighing 3kg or less can be accomplished safely and e ectively with properly selected devices in selected patients.

Transcatheter closure LAA aneurysm is possible in certain patients with suitable anatomy as an alternative to surgery. We have performed transcatheter closure of large LAA aneurysm in a 17 year old girl presented with recurrent stroke using 24 mm Amplatzer muscular VSD occluder. This case represents the rst known closure of a large left atrial appendage aneurysm with a percutaneous septal occluder device.
Case History: A 17 yr old female was referred to echocar- diographic examination to rule out patent foramen ovale
