hemodynamics for Groups A, B and a Control group C (patients not referred for closure) were compared. The per- centage fall in cardiac index with test occlusion was 18.12 ± 15.68 % in Group A and 33.75 ± 14.98 % in Group B (p = 0.019). There was no signi cant di erence in the rates of plastic bronchitis, PLE, stroke and need for subsequent heart transplantation between the patients in the 3 groups.
Conclusions: Using our institutional criteria, transcath- eter device closure of Fontan fenestration was followed by signi cant increase in the oxygen saturations and no signi cant di erence in morbidity or mortality between the closure and non-closure groups. Further prospective randomized studies are needed to identify the patients who will bene t from device closure of patent Fontan fenestrations.
17. TRANCATHETER CLOSURE OF ATRIAL SEPTAL DEFECT WITH THE FIGULLA ASD OCCLUDER. A COMPARATIVE STUDY WITH THE AMPLATZER SEPTAL OCCLUDER: A SINGLE CENTRE EXPERIENCE Radhakrishnan Sitaraman, Sushil Azad, Roli Shrivastava Fortis Escorts Heart institute, New delhi, India
Background: Transcatheter closure of atrial septal defect (ASD) is a well established and well accepted alternative to surgical therapy and is considered safe and e ective. Devices available for ASD occlusion combine di erent properties like self centering mechanism to allow achieving good positioning, ability to recapture and redeploy device. The Amplatzer septal occlude (ASO: St Jude Medical) has been widely used with favourable follow up results. More recently the Figulla ASD occluder (FSO: Occlutech, Germany) has been developed with structural innovation
Aim: To perform a retrospective comparison of the two occluders
Methods: From January 2016 to December 2017, 108 con- secutive patients underwent percutaneous ASD closure. 77 with FSO and 31 ASO devices.
Results: There was no signi cant di erences between two groups regarding patient demography. In ASO group (31) 12 (38.7%) were males and 19 (61.3%) were females. The median age was 29 years (range 4 to 58 years). Implantation was successful in 96.67% (30/31) patients. The mean device to defect ratio was 1.33 (range 1.18 to 1.6). In FSO group (77) 36 (46.7%) were males and 41 (53.2%) were females. The median age was 26 years (range 3 to 79 years). Implantation was successful in 76/77 patients. The mean
device to defect ratio was 1.32 (range 1.05 to 1.7). In ASO group 1 device embolised and in FSO group also 1 device embolised. In both ASO and FSO groups there was no inci- dence of arrhythmia, pericardial e usion in the immediate post procedure period. During follow up period (mean 11.9 months) in ASO group there was no residual shunt. One patient had a small shunt through the adjacent ASD close to the device. In FSO group mean follow up was 8.36 months.
In FSO group there were 5 patients with multiple ASDs, of which 2 patients single device used, 1 patients required implantation of 2 devices, 1 patient required 3 devices. No incidence of erosion, thromboembolism, endocarditis or late embolism in both groups.
Conclusion: Transcatherter closure of ASD with FSO is fea- sible and safe. FSO results are comparable with ASO results. However long term results that include more patients are mandatory.
18. ASSESSMENT OF FETAL INTRA-CARDIAC HEMODYNAMICS DURING FETAL BALLOON AORTIC VALVULOPLASTY: CORRELATION WITH FETAL ECHOCARDIOGRAPHIC FINDINGS AND POTENTIAL UTILITY IN PREDICTING PATIENT OUTCOMES

Background: In-utero balloon aortic valvuloplasty increases the likelihood of a biventricular (BiV) circulation in fetuses with severe aortic stenosis. Current predictors of BiV circulation focus on echocardiographic assessments of left ventricular (LV) systolic pressure and size. Using a pressure wire instead of a standard guidewire, intra-car- diac pressures can be measured during fetal aortic valvu- loplasty (FAV) and may enhance predictive models for a BiV circulation and improve our understanding of correlations between intracardiac pressures and echocardiographic measures in the fetus.
Methods: We performed a descriptive retrospective review of FAV procedures performed at our center using a pressure wire to measure fetal intra-cardiac pressures. Measurements of LV end diastolic pressure, LV systolic pres- sure, and aortic valve gradient were compared to pre- and post-natal hemodynamic and functional assessments by echocardiography, and post-natal circulatory physiology.
