Evaluation of Radiation Exposure and Image Quality in Congenital Catheterization Laboratory; A Single Centre Comparative Study Using Different Acquisition Modes

Abstract

he exposure to ionizing radiation delivered during the catheterization procedures has various negative biological effects to the patient, so concern has risen sharply about radiation hazards over the past decade. While angiography imaging system vendors have all made great strides with new technologies that reduce the amount of x-rays needed while maintaining excellent image quality, the procedures have become more complex, lasting longer and require more imaging than standard procedures. Survival for patients with congenital heart disease (CHD) has improved dramatically over recent decades and more than 85% of people born with a heart defect are now expected to survive to adulthood. Many of these patients need multiple catheterization procedures, multiple multi slice CT scan and chest x-ray pre-and post-operative, the risk of cumulative radiation form all this procedures with improvement of prognosis is gaining attention. Our study aimed to reduce radiation exposure during cardiac catheterization in CHD patients by using different acquisition modes, and measuring its effect on image quality and operators satisfaction. We studied 90 patients undergo cardiac cath. for CHD at Ain Shams University hospital. Patients were randomized into three groups according to mode of acquisition u
