The estimated risks associated with radiation exposure are higher in children compared to adults. The use of uoroscopy in diagnostic and interventional cardiac catheterizations being done in children requires accurate determination of the associated e ective dose. Diagnostic procedures such as right and left heart studies (R&L Heart) and interventional procedures like closure of patent ductus arteriosus (PDA) or atrial septal defect (ASD), pericardial tap and balloon angioplasty of pulmonary or aortic valves, branch pulmo- nary arteries or coarctation of the aorta are among the commonest procedures done for the pediatric age group undergoing cardiac catheterization.
In this study the results of an analysis of doses recorded for 203 cases over 2 years (2013 and 2014) carried out in pediatric patients. These data likely represent the largest set of radiation doses recorded in children undergoing cardiac catheterization. The maximum Kerma Aria Product (KAP) recorded for those patients were 9779 cGy.cm2. The maximum Cumulative Dose at the Interventional Reference point (CD_IRP) was also evaluated and found to be approximately 999 mGy. Body weight (BW) and body surface area (BSA) were also considered.
Materials and Methods: Two X-ray biplane uoroscopy were used in this study. patient’s age, weight, height, gender, and procedure type and uoroscopy time. Kerma Aria Product (KAP) and Cumulative dose data were recorded for 198 patients. The average pediatric age, weight and height were 3.03 years, 13.8 kg and 88.4 cm respectively. Peak voltage was 60.8kVp – 80 kVp.
Conclusion: Evaluation of KAP and CD_IRP doses are important indi- cators for the pediatric dose management and it is recommended to
include all those data in patient’s records. Body weight is an impor- tant factor in determining the radiation dose for children undergoing cardiac catheterization. Using a newer technology and adopt di er- ent imaging protocols (reducing the P/s and F/s) would lower the radiation dose without compromising the image quality.

Background: The presence of low birth weight, extra cardiac anom- alies or genetic syndromes has been associated with poor outcome with Norwood procedures for palliation of Hypoplastic left heart syn- drome (HLHS). Children with Turner syndrome and HLHS have a very high operative mortality and post-operative complications from per- sistent pleural e usions. Thus, for these high-risk patients, a hybrid approach to the Norwood operation can be an alternative palliation strategy. There is limited literature about outcomes of hybrid proce- dures in patients with Turner syndrome.
Methods: We present two cases of Turner syndrome with HLHS, who successfully underwent hybrid procedures as initial palliation for HLHS who subsequently underwent surgical repair achieving two-ventricle circulation.
Results: Two patients with Turner syndrome underwent hybrid Norwood palliation at 9 and 14 days of age. Weight at the time of intervention was 2320 grams and 2300 grams and both had placement of an 15mm x 5mm and 17mm x 7mm pre-mounted stent expanded and the pulmonary arteries were banded down to 3.5 mm diameter. These procedures were performed in the cath- eterization laboratory. The CHSS risk score was +17.93 and 15.35 (positive number favors a Univentricular repair, with the magni- tude of the di erence expressed by the number). In both children
