Seven-second X-ray scan detects severity of heart valve regurgitation in patients with repaired congenital heart defects

Researchers at Kyushu University have developed a simple, rapid, and low-radiation X-ray technique that can evaluate the severity of a heart condition known as pulmonary valve regurgitation—a common and clinically significant complication after surgical repair of a congenital heart defect known as Tetralogy of Fallot. The test only requires a scan of seven seconds and can evaluate the patient with 93% accuracy.
