Three-Dimensional Rotational Angiography in the Pediatric Cath Lab: Optimizing Aortic Interventions.

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Congenital heart disease (CHD) often involves aortic anomalies requiring interventions.
• Limited data exists on the use of three-dimensional rotational angiography (3DRA) in CHD aortic interventions.

Purpose of the Study:

• To evaluate the usability and accuracy of 3DRA during aortic interventions in patients with CHD.
• To compare 3DRA with conventional angiography in terms of accuracy, procedure time, and radiation dose.

Main Methods:

• Retrospective analysis of 77 patients with aortic issues undergoing 3DRA between January 2010 and January 2014.
• Accuracy assessed by comparing aortic diameter measurements between 3DRA and conventional biplane angiography (n=60).
• Clinical benefit evaluated using a Likert scale; fluoroscopy time and radiation dose compared to a control group.

Main Results:

• 3DRA showed high accuracy in aortic diameter measurements (average deviation 3.89%, r=0.99, p<0.0001).
• Clinical benefit was observed in 98% of cases.
• Reduced median fluoroscopy time (10.2 to 8.30 min, p<0.01) and radiation dose (0.18 vs 0.56 Gy cm(2)/kg, p<0.02) were noted.

Conclusions:

• 3DRA is an accurate and effective imaging technique for aortic interventions in CHD patients.
• It offers improved diagnostic accuracy and procedural simplification compared to conventional angiography.
• 3DRA enhances patient safety and has the potential to reduce radiation exposure.
