64-slice multidetector-row computed tomographic angiography for evaluating congenital heart disease

Area of Science:

• Cardiovascular Imaging
• Pediatric Cardiology
• Radiology

Background:

• Congenital heart disease (CHD) diagnosis requires precise anatomical assessment.
• Conventional imaging modalities have limitations in evaluating complex CHD.
• Multidetector-row computed tomographic (MDCT) angiography offers potential for improved CHD evaluation.

Purpose of the Study:

• To critically assess the role of 64-slice MDCT angiography in evaluating congenital heart disease.
• To analyze the impact of 64-slice MDCT angiography on management strategies for CHD patients.
• To compare the diagnostic capabilities of 64-slice MDCT angiography with conventional imaging techniques.

Main Methods:

• Sixty consecutive patients with CHD underwent 64-slice MDCT angiography.
• Patient data included median age (4.7 years) and weight (16.5 kg).
• Results were categorized diagnostically, and impact on management was analyzed.

Main Results:

• 64-slice MDCT angiography provided clear advantages over conventional imaging for CHD evaluation.
• The technique offered specific clues for surgical and interventional management.
• Correlation with surgical anatomy was excellent in surgically treated cases.
• A management algorithm was developed based on pulmonary artery anatomy assessment.

Conclusions:

• 64-slice MDCT angiography represents a significant advancement in cardiovascular imaging for CHD.
• The technique plays a crucial diagnostic and decision-aiding role.
• 64-slice MDCT angiography may largely replace diagnostic cardiac catheterization for evaluating great vessel anomalies in CHD.
