"It is infinitely better to transplant a heart than to bury it to be devoured by worms" (Barnard). For a long time I have wanted to pursue Cardiothoracic Surgery as a career. This is an occupation that specializes in surgical treatment of the heart and lungs. I believe I got my interest in medicine from Dr. Heidi Lakes M.D./O.B, otherwise known as my mother. Before she stopped practicing, she was an OB/GYN (Obstetrics- Gynocologist) at St. Thomas Memorial Hopsital. On occasion, I got to see her patients and had their conditions and surgeries explained to me. From then on, the hospital stuck as my favorite place. As for my choice in topic and specialty, I am fascinated by the heart because of how it can be one of the most delicate organs in …show more content…
Other, less severe damage hearts can be fixed with other treatments and procedures such as valve replacement and chest tubes to remove blood. There’s surgery has multiple steps and details. The first step is being put under general anesthesia. A cut is then made on the patients breastbone. The patience origins are then put on a heart lung bypass machine. Named and created by John Heysham Gibbon in 1953, this device continues to pump blood and breathe while the organs are stopped. This way a surgeon can work on the body without the movement of the heart and lungs in their way. The diseased heart is then removed and the donor heart is put in its place. The machine is disconnected and the new heart, hopefully, takes …show more content…
In the following days they stay in the hospital and are closely monitored for any signs of rejection and or post-operative infection. The recovery period last for about 2-3 months whilst having regular check-ups and blood tests. These will continue for the rest of the patients life. The body's immune system, when presented with a foreign body, will create antibodies to fight it off. This is what happens with transplanted organs. For that reason, patients will take many drugs that suppress this response. They also take these for the rest of their lifespan. Though the patients life post-operation, will be drastically changed by and inability to do rigorous exercise, smoke, etc., their life extension should be
In 1932 DeBakey invented the roller pump for the heart and lungs machine. The device is rhythmically powered by a flexible tube which is an important part of the lung-heart machine applied in the heart surgery. It has the ability to replicate the rhythm of human’s heart. As a result , it is named peristaltic pump.[1]
There are four different categories of treatment: lifestyle changes, surgical procedures, non-surgical procedures, and medications. Lifestyle changes include having a healthy diet; increasing physical activity; eliminating cigarettes, alcoholic beverages, and illicit drugs; and getting enough rest and sleep; losing excess weight. These lifestyle changes are to lower the patient’s blood pressure, cholesterol, and reducing any other future medical conditions. There are also surgical options to help cure, prevent, or control cardiomyopathy. Surgical method include a septal myectomy, surgically implanted devices, and a heart transplant. A septal myectomy is used to specifically treat hypertrophy cardiomyopathy which is where the heart muscle cells enlarge and cause the walls of the ventricles to thicken. The thickening of the walls may not affect the size of the ventricles but instead may affect the blood flow out of the ventricle. Usually along with the ventricles swelling, the septum in between the ventricles can become enlarged and block the blood flow causing a heart attack. When medication is not working well to treat hypertrophic cardiomyopathy, a surgeon will open the chest cavity and remove part of the septum that is blocking blood flow. Surgically implanted devices include a pacemaker, a cardiac resynchronization therapy device, a left ventricular assist device, and an implantable
Once becoming a cardiologist the extended odyssey begins. In a typical day cardiologists can engage in a multitude of activities. Most cardiologists spend their typical days diagnosing patients, interacting with them and engaging in different procedures to help the heart. What they can also do is, they can review patients charts and from that they determine which steps need to be taken. For instance, cardiologists can insert pacemakers which are artificial devices that are placed near the heart inside patients for stimulating the heart muscle and regulating its contractions. In addition, cardiologists can insert stents which are tubular supports placed temporarily inside a blood vessel, canal, or duct to aid healing or relieve an obstruction. What they can also do is that they check up on the patients that need the most help and they can sometimes make CT scans or CMRI’s ( Cardiac Magnetic Resonance Imaging). In addition, cardiologists can check on patients that have just had surgery and see how they are progressing. Along with checking on patients, when performing procedures on pa...
This machine used an intravenous drip which was hooked up to the patient. The IV would start dripping a solution of saline. When the patient was ready they pushed a button and this solution would stop dripping. At this time the machine would release a drug called thiopental, better known as sodium pentothal, a general anesthesia for sixty seconds. After this the patient would be in a coma. A timer would stop the first drug and the release the next one called potassium chloride. This drug will cause a heart attack and the patient will die in their sleep. (Gibbs, McBride-Mellinger; PBS.org.
Cardiomyopathy is a disease of the heart muscle, causing the heart muscle to become enlarged, thick or rigid. In rare cases, the muscle tissue in the heart is replaced with scar tissue.
Without regard to the patient David, he has potential to receive the heart transplant. The reports of the other patients are unclear
Ronnie Oldham once said, “Excellence is the Result of Caring more than others think is Wise, Risking more than others think is Safe, Dreaming more than others think is Practical, and Expecting more than others think is Possible.” Compassion runs through the veins of Cardiovascular Surgeons everywhere. They knowingly go into a field of study where no guarantees are promised and then strive to succeed. Cardiovascular surgeons save the lives of many people by operating on life threatening diseases that occur in the organs within the chest, and the bony structures and tissues that form the thoracic cavity. They must possess many skills, the first and foremost being humanistic skills, other skills include leadership skills, the ability to make arduous decisions with limited information and, more often than not, a miniscule period of time, and lastly, of course, impeccable knowledge of the human heart and body, along with outstanding surgical skills. Many people find that they do not have the expertise nor the mental strength to be a cardiovascular surgeon which is why it is a career best left to the undaunted.
(Slide 2) What is Cardiomyopathy? If we break down the word we can see “Cardio” which means of the heart, “myo” which means muscle, and “pathy” which means disease, therefore cardiomyopathies are diseases of the heart muscle. (Slide 3) There are 3 main types of cardiomyopathies; hypertrophic, dilated, and restrictive. I will only be discussing dilated cardiomyopathy, which is characterized by the enlargement of the hearts chambers with impaired systolic function. It is estimated that as many as 1 of 500 adults may have this condition. Dilated cardiomyopathy is more common in blacks than in whites and in males than in females. It is the most common form of cardiomyopathy in children and it can occur at any age (CDC).
Throughout this researched that I investigated I became interested in this field in a way. If I had an option in medical field I would take the option. Knowing that you are helping patients out is an amazing feeling. I would work with infants rather than adults. I would cherish every moment because you would never know if that’s the last time to work with the patient not just because of death but maybe cause they might recover from there sickness.
...as become increasingly necessary to obtain a second and even a third opinion because surgery is expensive, and physically invasive and traumatic for the heart patient.
During this internship I had a variety of tasks that made me understand and develop my skills in cardiac rehab, stress testing, working at the hospital in the CVCU, and also talking to the patients in the hospital about coming to outpatient cardiac rehab. During my time in the outpatient cardiac rehab I have learned and perfected how to take a manual blood pressure, check heart rates, oxygen levels, and be able to teach and instruct our patients on healthy habits to ensure they are staying healthy and active outside the rehab facility. I learned to do a full disclosure on a patient, meaning to check their EKG, find out their max heart rates during exercise, and send a note to the doctor if anything abnormal should occur. I’ve learned to chart and tech
I love hospitals. My interest sparked when my mom would take me to visit people who were sick and I would watch the hustle and bustle of the hospital floors. The go-go-go atmosphere drew me in from the beginning and I enjoyed asking everyone about what they did. Consequently, when the time came to choose a career I looked for something that provided the option to work in a hospital providing one-on-one care to people. This is how I discovered speech and language pathology.
This is the story of Christiaan Barnard an excellent African cardiac surgeon who performed the first human-to human heart transplant. He was born in Beaufort west, Cape Province, Union of South Africa on November eight, 1922. He grew up in Beaufort West and his family wasn’t rich. Adam Barnard, his father, was a church pastor and his mother, Maria, played church organ. Christiaan Barnard lost one of his four brothers, Adam, because he had a heart problem disease. Adam died at the age of five. In 1940, he matriculated from the Beufort West High School. Five years later, he obtained his Bachelor of Medicine of Surgery at the University of Cape Town.
When I was at my rotation in medical school, after seeing patients in the medicine unit and learning about diabetes, hypertension, and various other diseases, I immersed myself in the field. I tried to figure out ways of contributing to the specialty even though I was just a medical student, and made up my mind to become an internist. After finishing my internal medicine rotations, I was sent to complete obstetrics and gynecology rotations. During the rotation, I was watching the senior doctors delivering babies and treat different diseases that women encountered. I looked at the new mothers and witnessed their happiness which drove my motivation in obstetrics and gynecology. After three months of obstetrics and gynecology rotations, I began a pediatrics rotation. Seeing the children there growing and overcoming whatever ailed them, with all their tears, pain, and joy, made me so overwhelmed I wanted to become a pediatrician.
After trimming, a cannula is inserted into the superior vena cava. Through this cannula, the preservation media can be pumped in. What if this scenario were different? What if doctors were able to preserve the donor heart and keep it viable outside the body for up to 24 hours instead of only four hours?
