Christina Markevich 10/29/2015 Congestive Heart Failure What is Congestive Heart Failure? Congestive Heart Failure is something that occurs when the heart is no longer able to pump enough blood to the rest of the body, or when is just is not able to pump blood as well as it should. Some people happen to have either of these problems, some people have both. What causes the heart to become weaker? There is a number of causes, but most of all, the arteries may narrow in the heart. That is another

Emergency Room with chest pain that has lasted for about 6 hours and is slightly relieved by nitroglycerin; the patient is also experiencing dyspnea as well as nausea. A fourth heart sound was discovered upon cardiac examination, and an angiogram revealed right coronary artery occlusion. Question: What is it that physiologically occurs during a myocardial infarction which leads to the formation of an S4 sound? Generate: Heart auscultation is useful in characterizing heart sounds and identifying abnormalities

Childbirth is a normal part of everyone’s lives. All humans are delivered through childbirth, and those who are born grow into a toddler, a child, a teen and to an adult. While the most known method is vaginal birth, sometimes this does not work because of dangers. The Cesarean section is a type of surgery where the baby is extracted from the abdomen. This method can come with benefits; but with many consequences as well. The C section (as it is often called) is where the delivery of a baby happens

Aberrant right subclavian artery (ARSA) is the most common aortic arch anomaly. The estimated incidence is 0.5-2%. They are often asymptomatic, but approximately 10% of people may complain of dysphagia lusoria4 or other compressive symptoms. In ARSA of the Innominate artery, the right subclavian artery arises as its own branch from the aortic arch distal to the origin of the left subclavian artery. Its relationship to the esophagus is variable with 80% posterior to esophagus, 15% between the esophagus

“Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. Heart failure does not mean that your heart has stopped or is about to stop working. It means that your heart is not able to pump blood the way it should. It can affect one or both sides of the heart” (Chung 2013). Mrs. Organa because your heart pumps is weak, the blood flow moves at a slower pace inhibiting sufficient nutrients and oxygen needed to meet the body requirements. It is important to make

Mitral valve regurgitation is one of the few heart conditions you may unknowingly have for years and learn to live with the affects of this condition before ever being diagnosed. Mitral valve regurgitation occurs when the mitral valve is letting blood leak backward into the upper chambers of the heart. The mitral valve is located between your heart’s two left chambers . Mitral valve regurgitation, or mitral insufficiency as it is known, is a common heart valve disorder. It is a disorder affecting

The mitral valve, which is also sometimes referred to as the bicuspid valve, is one of the four cardiac valves1 in the heart, located beneath the left atrium and above the left ventricle (Figure 1), preventing backflow of blood between these two chambers of the heart. The word mitral comes from the latin word mitra which translates as a turban or belt2. Figure 1 Diagram showing where the heart chambers, blood vessels and valves are located3 Figure 2 Cross section of the heart, showing

Introduction Before My Heart Stops is the memoir of Paul Cardall who was born with a congenital heart defect and his life, faith, disappoint, sorrow, heart transplant, and the new chance of life. Cardall was born with a double inlet left ventricle (DILV) and had his first surgery in less of 24 hours of birth and parents were given the news that their infant son life expectancy was short. Cardall, at the age of 36 was the longest living person with congenital heart defect/disease in the state

INTRODUCTION Phonocardiogram is a physiological signal that results from the vibrations created by closure of heart valves and it represents the recording of the heart sound signal. A normal cardiac cycle is comprised of two major sounds- first sound (S1) and the second heart sound (S2). The first heart sound has four components in it, due to the closure of AV and semilunar valves. The second heart sound has two components, one due to closure of aortic valve and another due to closure of pulmonary

A young couple wakes in their beds , the first day home since they had their baby. But something is wrong, their child is not in its’ crib, instead he is still in the hospital , the neonatal intensive care unit to be exact. He has to have surgery ,because he was born with a congenital heart defect. What are congenital heart defects? In order to understand congenital heart defects, first we must understand what those words mean. Congenital means something one is born with, therefore congenital heart

This defect is actually in the septum the wall that separates the right and left sides of the heart. A hole in the wall between the two upper chambers is called an atrial septal defect, or (ASD). This is one of the least complex forms of congenital heart defect of the many in infants, and was one of the first types to actually be repaired surgically. Normally, low-oxygen blood entering the right side of the heart stays on the right side, and subsequently oxygen-rich blood stays on the left side of

prevent any heart problems from occurring, but as that is not entirely possible new devices are helping save people 's lives. Three devices and treatments that are being used in hospitals today include, Transcatheter Aortic Valve Replacement, Left Ventricle Assist Device and a MitraClip. These treatments and devices are making a huge impact on how heart problems are being treated in hospitals to save people 's hearts and lives. With

prevent calcification that was prevalent in the previous mechanical valves. Calcification occurs when calcium deposits stick to the valve flaps which hinders the movement of the valve and the ability to allow fluid to move back in the atrium or ventricle that it originally came from. The structure of the bileaflet heart valve is fairly simple. It is composed of a suture ring that attaches to heart tissue after the hold valve is removed. There are two leaflets that attach to the outer circle and move

“An average heart has four chambers; two upper, called the atria and two lower, called the ventricles. The right side of the heart receives blood that is returning from the body. This oxygen-lacking blood arrives in the right atrium, where it is pumped into the right ventricle.” (Blaser). This is the structure of the heart, an organ every person in the world has, and that so happens to be the most important organ in an organism’s body. The heart helps people get oxygen, keep the organs alive, and

Congenital heart disease is a problem with the structure of the heart. It is present at birth. Congenital heart defects are the most common type of birth defect. The defects can involve the walls of the heart, the valves of the heart, and the arteries and the veins near the heart. They can disrupt the normal flow of blood through the heart. The blood flow can slow down, go in the wrong direction or to the wrong place, or be blocked completely. The sign and symptoms of severe defects in newborns

Based on the anatomy of the heart, heart tissue, and the heart valves, certain material specifications need to be taken into consideration to ensure that artificial heart valves function like normal healthy heart valves. When one of the four heart valves can no longer function sufficiently it may need to be replaced with an artificial heart valve. There are two main types of artificial heart valves: mechanical, and biological. Mechanical heart valves can be grouped by their method of implantation;

Supraventricular Tachycardia, Pediatric Supraventricular tachycardia (SVT) is the most common type of abnormal heart rhythm in children. It can make a child’s heart beat very quickly. This can be frightening, but it is rarely dangerous. Episodes of SVT start suddenly and usually go away on their own. Children with SVT usually do not have other heart abnormalities. Most babies with SVT outgrow it by the time they are one year old. Older children may need treatment if the episodes are frequent and

1a, Figure 1b). The rest of the otolaryngologic examination was normal. On auscultation, a loud systolic murmur at left sternal edge heard. No carotid bruit. A referral was made to the cardiologist and echocardiography showed pulmonary arterial and right ventricular dilation. Computed tomography (CT) of the neck and thorax showed enlarged pulmonary trunk and artery(Figure 2b). The patient was diagnosed with atrial septal defect(ASD). The patient underwent surgical heart repair of the defect and post-operatively

the heart.(37) The heart is surrounded by pericardial membrane which consists of visceral and parietal portions.(37) The heart is formed of two ventricles and two atria.(37) Each ventricle is cone shaped, with thick wall, pointed apex and broad base.(37) The two ventricles

that the left ventricle could hold approximately two ounces of blood through his study of cadavers. This information was essential because he could use this to approximate how much blood passes through the heart every half hour. It was readily verifiable that the
