Solution
It is almost impossible to repair intracardiac defects surgically while, the heart is still pumping. Therefore, many types of artificial lung machines have been developed to take the place of heart and lungs during the course of operation. Angiogeaphy is rediographic visualization of blood vessels of a region/ organ after injecting a radio-opaque / contrast agent (eg, iodine) or flemical. Digital substraction angiograohy is an imaging technique that produces clear views of flowing blood in vessels and indicates the pesesnce of blockage.
X-rays have a remarkable ability to penetrate materials, which do not transmit visible light. X- ray imaging is commonly employed for diagnosing disesase of heart, lungs and bones.
