America has come a long way since improvements in medical technology and treatments have been made. As time has passed, modern medicine has continued to shape America and its medical practices, pushing it to become a much more medically advanced nation. From the birth of catheterization to the interventional era of the development of surgeries, drugs, imaging and treatments, the history of invasive and interventional cardiology is a field of modern medicine that has moved to another level, transformed the way medicine is used , and ultimately changed the way America saved lives. Invasive and interventional cardiology is the study of a group of methods in which diagnostic tests and non-surgical interventional treatments are used to treat patients suffering from various heart diseases and disorders such as atherosclerosis (hardening of the artery walls) and coronary heart disease ( accumulation of plaque in the coronary arteries). This field covers a variety of therapies ranging from stents to intravascular ultrasound. Invasive and interventional cardiology began with the birth of catheterization, starting from the first ancient Egyptians, dating back to 400 BC. During 400 BC, catheters were made from hollow rods and tubes were used on cadavers to study the function of heart valves. Then, in 3000 BC, the ancient Egyptians performed the first types of catheterization that started from the bladder using metal tubes (Choudhury, Rahman, Azam, and Hashem 75). With the basic beginnings of inserting tubes and tubes, these ideas began to shape the minds of doctors. The first major breakthrough that led to the birth of catheterization was a description of blood flow and blood itself made by William Harvey in his “earth-s...... middle of paper ......on.
