Open-heart surgery had been one of the largest life saving surgeries performed. The first successful open heart surgery was performed in 1952 by Dr. F John Lewis. He used ice to cool down the heart and slow circulation. The basis of heart surgery involves exposing the heart (open). The sternum must be sawed through to expose the heart. The heart cannot be left pumping during surgery. At first ice was used but now a heart lung machine is used. It involves hooking a tube up to the aorta. Blood goes

Question 3 Needs Grading Placement of a dual-chamber pacemaker. Using a standard technique‚ the left infraclavicular subcutaneous pacemaker pocket was created with sharp and blunt dissection. The 2 j-tipped guidewires were advanced through a left subclavian vein using standard left subclavian venotomy under fluoroscopic guidance. The peel-away sheaths and introducers were advanced over the guidewires‚ and the guidewires were removed. The pacemaker leads were advanced under fluoroscopic and electrophysiologic

INTRODUCTION: Magnetic Resonance Imaging(MRI) is a non invasive medical imaging method widely used in hospitals and in research. In year 1946 Felix Bloch of Standard /university and Edward Purcell of Harvard University made the first succesful nuclear magnetic resonance experiment to study chemical compounds‚ they were awarded the Nobel Prize for physics in 1952. In early 1980 ’s the first human magnetic resonance imaging( MRI) scanners became available‚ producing images of the inside of the
