Heart murmurs are created by an abnormal turbulent flow of blood. The sound is provided by your heart is from the flow of blood through your atria chambers to your ventricles. This can be caused by fever, anemia, high blood pressure, or overproduction of the thyroid hormone. Another possibility could be the function of the valve. Mitral valve prolapse or mitral valve stenosis are reasons for the functioning of a bad valve.
In 1816, René Laennec had received a pregnant female with a heart malfunction as a patient. In doing so, he thought to take a sheet of paper and roll it tightly, placing it against over her heart and lower chest region, He heard her heart pulsating. The piece of paper became to be known as stethoscope. He described this …show more content…

However, in heart murmurs it is most common in newborns or infants. Although, adults can obtain a heart murmur as well. Heart murmurs may come even be found within your genes. Many women receive heart murmurs during pregnancy. In fact, women are more likely to receive a heart murmur than men. Heart murmurs have a few unnoticeable signs and symptoms. A symptom may be swelling or sudden weight gain, heavy sweating, or enlarged neck veins. However, they still have some concerning signs, which may be shortness of breath, skin appearing to have a bluish color, chest pain, dizziness, fainting, or enlarged liver.If experiencing any signs or symptoms it may be necessary to see a doctor. Many cases are not fatal; however, diseases left untreated or unnoticed may become an …show more content…

The medical examiner must first establish the location of the heart murmur, The stethoscope must be placed only at the apex or chest wall, may even sometimes on the left sternal border. Timing is the next step, using the heart beats they must first determine if it is a systole or diastole murmur. Then must ask themselves if their is a delay or at the same time. The third step in the diagnosing process is the intensity of the murmur. Heart murmurs are graded on a scale to I to VI (very faint with stethoscope to without using a stethoscope at all). The pitch of the murmur can only be heard with a stethoscope; however, it will most likely be low and faint. Heart murmurs sound like whistling, rumbling, blowing, harsh or sometimes musical. They let off radiation into a patient 's’ axilla, left shoulder, and

Pathophysiology When Pulmonary Stenosis is present, resistant to blood flow cause right ventricular hypertrophy – right atrial pressure will increase – reopening of the foramen ovale, shunting of unoxygenated blood into the left atrium, systemic circulation. Clinical manifestation: Cyanosis, characteristic murmur , cardiomegaly . Treatment: Baloon angioplasty (neonate).

Annexe 1 : Heart murmur 1. An unusual sound coming from the heart that can be detected by a stethoscope. These noises are caused by an abnormal turbulence produced when blood flows across one of the heart (valves, cardiac chambers) and or vessels close to the heart Heart murmurs are classified by the intensity of the sound heard: Stage I (murmur is of low intensity and can hardly be heard) to Stage VI (murmur is extremely loud).

Sadly there are many pediatric heart conditions in the world that are treated every day, and many more arise as well these cases include ASD, VSD, PDA and TOF. The first major condition being Atrial Septal Defect (ASD). 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.

Firstly, the formation of the valve must be correct, and it must be flexible enough to undergo the movements required of the it to ensure efficient function. Secondly, the valve must be able to open up to a certain diameter to allow the correct volume of blood to pass through into the left ventricle. Finally, the valve must be able to close firmly, in order to prevent any blood leaking back into the left atrium7. The competence of the mitral valve is essential to the efficient functioning of the cardiovascular system, and when one of the above criteria for an efficiently functioning valve is not met there are several conditions that can develop, which can and do cause many problems for those who suffer from them. The most common problems include mitral valve regurgitation, mitral valve stenosis and mitral valve

1) In mitral stenosis a diastolic murmur is present due to stenosis, or narrowing of the valve. The murmur is heard when the mitral valve fails to open appropriately in diastole. The leaflets of the valve are usually thicker, stiffer, and become misshapen from the effects of rheumatic fever or a congenital defect (Porth, 2011). The crackles in her lungs are likely due to left sided heart failure leading to pulmonary hypertension.

High blood pressure as well as earlier heart surgeries have also been linked to atrial fibrillation. In some cases, lung diseases have been thought to be involved in the development of atrial fibrillation for example lung cancer, sarcoidosis, pneumonia and pulmonary embolism, as well as breathing problems associated with sleeping

Family history and symptoms must be there to confirm diagnosis, and other tests may be performed to determine if the disease is present or not. One of the first tests that would be performed or recommended would be an echocardiogram. This will check to make sure the heart valves and size of the aorta are normal. Computerized tomography or magnetic resonance imaging may be used as well. If someone were to have the disease they will receive regular echocardiograms to monitor the heart.

Transposition of the Great Arteries, Pediatric A good way to understand this condition is to first think about how blood flows in the body. Arteries are blood vessels that carry blood away from the heart to other places in the body. The two largest of these arteries are called the great arteries. One of them, the pulmonary artery, takes blood from the heart to the lungs.

Mitral valve insufficiency causes There are two types of this insufficiency: congenital and acquired. Congenital mitral insufficiency may be caused by adverse factors, which were accumulated during pregnancy. Such adverse factors include smoking, alcohol consumption, infections and polluted environment. Acquired insufficiency of the valve can be a result of trauma or tumor.

This discovery greatly contributed to the understanding of the human anatomy and cardiology. Avicenna stated that every beat of the pulse contained two movements and two pauses, therefore describing it as expansion, pause, contraction, pause. This innovation led to his discovery of the modern approach of measuring pulse by the wrist, a useful technique still practiced today. Checking your pulse is a free and simple way to check the condition of your health, and the strength of your heart. The heart is the main organ of the body and maintaining its condition is significant to your health.
