America has come a long way since improvements in medical technology and treatment have been made. As time has progressed, modern medicine has continued to shape America and its medical practices, moving it towards becoming a much more medically advanced nation. Ranging from the birth of catheterization to the interventional era of development of surgeries, drugs, imaging, and care, the history of invasive and interventional cardiology is a field of modern medicine that has stepped up to another level, transformed the way medicine is utilized, and ultimately, changed the way America has saved lives.
Invasive and interventional cardiology is the study of a group of methods in which diagnostic testing and non-surgical interventional treatments are used for treating patients who suffer from various heart diseases and disorders such as atherosclerosis (hardening of artery walls) and coronary artery disease (plaque build-up in coronary arteries). This field covers a variety of therapies ranging from stents to intravascular ultrasounds. Invasive and interventional cardiology began with the birth of catheterization, starting from the early ancient Egyptians, going back to 400 B.C. During 400 B.C., catheters were fashioned by hollow reeds and pipes were used on cadavers to study the function of cardiac valves. Then, in 3000 B.C., ancient Egyptians performed the first types of catheterization which started from the bladder using metal pipes (Choudhury, Rahman, Azam, and Hashem 75). With the very basic beginnings of inserting pipes 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 by William Harvey in his “earth-s...

Transcatheter aortic valve replacement or TAVR is the latest technology used principally for the treatment of aortic stenosis, a condition in which one of the major valves of the heart, the aortic valve, becomes tight and stiff, usually as a result of aging (3). Since many patients who need aortic valve replacement for aortic stenosis are too sick to undergo major valve replacement surgery, they are unable to get the treatment they need. With the transcatheter aortic valve, this issue is bypassed because this valve can be implanted in the heart by accessing the patient’s heart through an artery in the groin. The valve can be inserted through a wire that can be pushed to the heart and the old valve is simply pushed to the side when the new valve is implanted. This technology has been in use in the US with Edwards’ Sapiens valve since 2011 and has saved the lives of many patients with aortic stenosis (4). Medtronic’s CoreValve uses similar technology and has won patent fights in Europe and has been in use internationally. However, within U.S., Medtronic has not been...
The purpose for the stent was to hold the coronary artery open to allow the blood to flow more freely.
In 1615 at the age of 37 Harvey became the Lumleian Lecture specializing in Surgery. William Harvey discovered his finding of the Circulation of Blood by ignoring medical textbooks and dissecting animals. He gained all or most of his learnings from observations of cutting open veins and arteries of living animals. Many people of this modern time thought because there weren’t any anesthetics that Harvey was cruel for cutting open living animals. I think that if it wasn’t for William Harvey and all of his studies and dissections that we wouldn’t be able to learn teach and save as many people as we can today. We as people have learned a lot from the many studies and dissections throughout Harvey’s lifetime. We have learned that blood, arteries, and veins are all within the same origin, blood in the arteries sent to the tissues are not stay there, the body‘s circulation mechanism was designed for the movement of liquid and that blood carrying air is still blood, the heart moves all movements of blood not the liver, hearts contract the same time as the pulse is felt, ventricle’s squeeze blood into main arteries, the pulse is formed by blood being pushed into arteries making them bigger, there are no vessels in the heart’s septum, lastly there is no to in from of blood in the veins there is only
Among the sterile field of the cardiac catheter laboratory, a student is observing over a cardiologist’s head while a surgical technician narrates their role in the standard ablation. This is just one of the many pivotal experiences that a student in Liberty High School’s Allied Health CTE program can expect. The student is on a path made available by the Western Maricopa Education Center and, if followed properly, that student can expect to graduate high school as a skilled worker in the medical field. Allied Health is just a small portion of a much bigger picture that provides ever growing opportunities to high school students prior to graduation.

First of all we need to understand the type of technology this device represents. Is this a sustaining innovation? Or is this a completely new disruptive product? After fully understanding this aspect we can make better decisions regarding the future of the firm and its product. This device offers many benefits that current products do not. As explained earlier, this device is extremely portable, offering emergency rooms the flexibility and convenience they seek to provide patients with the best treatment possible. Likewise, this product will come in at a price point much lower than current echocardiographies, further separ...

What I wanted to talk about today is this life save device called a automated external defibrillator. It has become the number one way to resuscitate a person who has had a cardiac arrest unwitnessed by emergency medical services and who is still in persistent ventricular fibrillation or ventricular tachycardia. Many people have played a big role in creating this device to become more efficient, smaller and easier to use for the general public. Here are just to name a few that played a part in the creation for this device: Claude Beck, James Rand, Paul Zoll, and Frank Pantridge. The first use of a defibrillator on a patient was in 1947 on a 14 year old boy. Claude Beck was performing a open-chest surgery when the boy went into fibrillation. Beck manually massaged his heart for 45 minutes until the arrival of the defibrillator. The defibrillator he used during surgery was made by James Rand and had silver paddles the size of large teaspoons. In 1956, Paul Zoll performed the first successful external defibrillation with a more powerful defibrillator. A major breakthrough in emergency medicine occur in 1965. At the time a majority of coronary deaths occurred outside of the hospital setting since defibrillator required a main power source and were only available in hospitals it made them pretty much useless in saving lives outside of a hospital setting. Frank Pantridge often referred to as the Father of Emergency Medicine, made the first portable defibrillator in 1965. This device was power by a car battery and weighted approximately 70 kg (155 lbs). By 1968 he was able to create a defibrillator that was safer to use and only weighted 3 kg (6-7 lbs). It was argued that their was a possibility of misuse of the device if given to a unt...
Cost effectiveness and noninvasiveness seem to be a theme in developing preventative treatments of coronary artery disease. A study presented by the Journal of Magnetic Resonance Imaging proposes that the use of coronary wall MRI would encompass both of these factors. These MRI images compared coronary artery thickness of symptomatic and asymptomatic patients. It was found that these images could successfully detect artery wall thickness in asymptomatic patients who would have otherwise not been screened for risk factors.
Coronary heart disease came in the public eye in the mid-20th century as a disease of pandemic magnitudes and it continues to be a major cause of death in the western world. The fundamental cause of coronary heart disease is Atherosclerosis. The term “atherosclerosis” is the combination of two Greek words which correctly imply the elements of the lesion. The first being “athero” the greek work for gruel which parallels to the necrotic core at the base plaque formation, and “sclerosis” from the Greek word hardening, corresponding to the fibrous cap on the outer layer of the plaque. (Vulnerable Atherosclerotic Plaque : Strategies for Diagnosis and Management, 1, 2)
The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...
For angioplasty, a special catheter (a long, thin, hollow tube) is inserted into a blood vessel and guided to the blocked coronary artery. The catheter has a tiny balloon at its tip. Once the catheter is in place, the balloon is inflated at the narrowed area of the coronary artery. This presses the plaque or blood
...nt for early detection of different diseases. Although they have been somewhat effective in the past, they need to be updated and improved so a wider range of diseases can be detected. Among these checkups, an emphasis should be made on checking for congenital heart defects, especially those who are hard to detect. This should be a priority because a baby with a CCHD could be at risk in the future. Furthermore, children who have a heart disease such as Wolff-Parkinson-White Syndrome are at greater risk. In these cases, early detection is key for eliminating this types of conditions. This way an appropriate treatment can be given at a younger age and a more permanent solution can be offered to eliminate the condition such as surgery. If the root of these types of diseases can be eliminated now, future generations can have a better healthy life quality and assurance.
...ital if you have symptoms such as dizziness, fatigue, chest pain, or heartburn it is essential that you get to a hospital immediately, just to make sure that you can get the treatment that you need so you and your family do not have to experience a myocardial infraction. Even though coronary artery disease usually affects persons over age 60, the disease can still be seen in people who are much younger for various reasons. The diagnosis of coronary artery disease remains the number one cause of hospitalization and death in the adult population in the United States today, but with the proper treatments, knowing the risk factors of coronary artery disease and medical technology such as stents, coronary endocartomy, and coronary bypass grafting that we have available to us today the prognosis can be positive for many patients and will save more lives than not knowing.
