Meeting Abstracts
medical charts, echocardiographic recordings, catheterization reports and uoroscopic lms were reviewed. Demographics, echocardiographic measurements of ASD, dimensions of device and hemodynamic data were collected. Prolonged procedure was de ned as duration from device deployment to its release exceeding 10 minutes. A statistical model was designed using stepwise logis- tic regression analysis. Receiver operating characteristic curves were plotted to nd best cut-o for signi cant predictors.
Results: The procedure was prolonged in 25 patients. By mono- variate analysis, the signi cant predictors for prolonged procedure were smaller and younger patients, larger ASD, smaller left atrial (LA) dimensions and device waist ratios to weight, patient’s length, and LA dimensions. By multivariate analysis, the signi cant predic- tors were de cient septal rim toward superior vena cava (SVC) and device waist diameter in relation to patient’s length (best cut-o : < 12 mm and > 0.13, respectively). Presence of Chiari network was not statistically signi cant, but it prolonged procedure duration. In three cases (3.7%) the device embolized; all had short SVC rim.
Conclusions: A short septal rim toward superior vena cava and large device waist size in relation to patient size and/or LA dimensions may predict prolonged procedure during PTCC of ASD. Chiari network may also be a risk factor. Short septum rim toward superior vena cava may be a risk factor for embolization.

PERCUTANEOUS VSD CLOSURE UNDER 1 YEAR OF AGE: Nazmi Narin, Ozge Pamukcu, Ali Baykan, Aydin Tuncay, Suleyman Sunkak, Kazim Uzum
Erciyes University, Kayseri, Turkey
Background and aim: Untreated large Ventricular septal Defects(VSD) are important reason of congestive heart failure in early infancy. This population usually fails to grow and surgical closure is challeng- ing because of congestion in their lungs prone to respiratory infec- tion and their bad nutritional status. We therefore planned to close VSD of such patient group under 1 year of age percutenously and wanted to share our experience.
Material & Method: We have performed VSD closure of 7 patients under 1 year of age between the dates September 2012- May 2016 in Erciyes University Pediatric Cardiology Department.
Results: Age of patients ranged between 4 months-12 months. Weightofthepatientsduringtheprocedurewasbetween5.3-9 kg. Mean VSD diameter was 3.19±0.47mm. One of defects was muscular, rest of them were perimembranous. All defects were closed with Amplatzer Ductal occluder II(ADO-II). Mean fluoros- copy duration and total radiation dosage were 78.5±94.6min, 2069±1395cGy/min respectively. We did not faced with any major complication except in one patient: complete AV block was seen one month after the procedure. Pacemaker was implanted. No aortic regurgitation was seen in patients after device implantation.
Conclusion: The procedure of VSD closure, whether it is surgical or percutaneous, is very risky. The risks were higher when the children were smaller than 1 year of age and low body weight. Percutaneous VSD closure may be an alternative to surgery in early infancy that carry the similar risks but less invasive.

Erciyes University, Kayseri, Turkey
Aim: Patent Ductus Arteriosus(PDA) is an important cause of morbid- ity and mortality in preterms. As birthweight decrease, risks increase. Main aim of our study is to emphasize the e ectiveness and safety of percutaneous PDA closure even in extremely low birth infants (less than 1000gr)
Material Method: In our center between the dates June2014- December2015, PDA of eight patients less than1000gr were closed percutaneously. To our knowledge this study includes the largest cohort of infants less than 1000g in the literature, whose PDA were closed percutaneously.
Results: Symptomatic patients, less than1000gr having PDA were included in the study. All have3times medical therapy for PDA closure but it didnotwork. PDA was decided to be contributor of this medical state of them. The mean patient age 16±5.9days. The mean weight of patients was 923±75.9gr. Mean gestational age was 27.2±1.28weeks.
