BIGGER ISN’T ALWAYS BETTER: INITIAL EXPERIENCE WITH THE 3.3 FR MONGOOSE® PIGTAIL CATHETER FOR AORTIC ANGIOGRAPHY DURING PDA CLOSURE IN SMALL PATIENTS.

Introduction: Use of a smaller vascular sheath in the femoral artery may be associated with lower vascular complication rates. The 3.3 Fr Mongoose® Pediavascular pigtail catheter is a new angiograph- ic catheter designed to allow higher flow rates and maximal burst pressures, potentially resulting in improved angiographic quality in a small catheter. We reviewed our initial experience with this catheter during PDA closure procedures and compared it to prior experience with 4 Fr pigtail catheters
Methods: Retrospective review of all patients in whom the Mon- goose® catheter was used for aortic angiography during PDA closure from 12/13-4/15. Inclusion criteria were weight ≤ 20 kg and presence of a PDA. Angiographic efficacy, procedural details and complica- tions were reviewed and compared to the prior 10 cases in which a more standard 4Fr angiographic catheter was used from 9/12-12/13. Variables are reported as median with range. Comparisons were per- formed using the Mann-Whitney U test; p value < 0.05 was consid- ered significant.
Results: Twelve patients (9 female) met inclusion criteria for this study and were catheterized with a 3.3 Fr Mongoose®. Median wt 10.5 kg (range 6.4-18.2), ht 81 cm (range 37-111) and BSA 0.47 m2 (range 0.33- 0.75) were not different from the 10 pts (3 female) in the 4Fr group (p= NS): median wt 9.9 kg (range 6-16.8), ht 80 cm (range 64-102) and BSA 0.46 m2 (range 0.31-0.74). Angiographic quality was subjectively adequate with both catheters in all cases with no objective difference in average pixel density between the 2 techniques [3Fr: 76.7 (range 33.5-90); 4Fr: 70 (range 38-102); p=NS]. Total contrast used was similar between the 2 groups (3Fr: 4.2 ml/kg; 4Fr: 4.9 ml/kg; p= NS). Radiation dose (air Kerma) was similar in the 2 groups [3Fr: 28.1 mGy (range 17.2-38);4Fr: 38 mGy (range 20.4-58.5); p = NS]. Echocardiography on POD# 1 demonstrated PDA closure in 10/12 3Fr pts and 10/10 4Fr pts (p=NS); at latest f/u, all are closed. No complications were encoun- tered in either group with good pulses and perfusion on POD#1.
Conclusions: The 3.3 Fr Mongoose® allowed for adequate and similar angiography to the more standard 4Fr pigtail catheter, allowing safe and effective transcatheter PDA closure in small children.

SIMPLE TECHNIQUE TO CREATE DIABOLO STENT CONFIGURATION – AMPLATZ GOOSENECK SNARE Abhay Divekar, Osamah Aldoss
University of Iowa Childrens Hospital, Iowa City, IA, USA
Introduction: The use of diabolo stents greatly aids in stent stability and creates an accurate predetermined waist. This is best described for creating transcatheter Fontan fenestrations. A number of tech- niques to create the diabolo configuration have been previously de- scribed.
