Echocardiography

Background and Objective The objective of this study was to evaluate the impact of routine early pulse oximetry screening (POS) on the rate of unexpected neonatal unit admissions and the need for echocardiography. The study also reviewed the outcomes of babies admitted to the level 3 NICU as a result of a positive POS testing. What is known prior to the study is that some cardiac defects are missed by antenatal ultrasound and routine clinical examination in the newborn period. Also, early…

AN ATHLETE 'S HEART Everyone knows normal daily exercise is beneficial to the heart. It helps reduce the risk of heart disease, reduces weight, lowers blood pressure, and improves cholesterol. A difference in the appearance of the heart can be seen between normal exercise and those of highly trained athletes. Athletic hearts undergo cardiac remodeling of chambers and physiological changes because the heart is working harder to pump blood to the rest of the body during extreme physical activity…

The mitral valve is a valve that allows blood flow from one chamber of the heart, the left atrium, to another called the left ventricle. In mitral valve prolapse, the valve slips backward due to the abnormal size of or damage to the mitral valve tissues. Mitral valve prolapse is a common cause of a heart murmur caused by a "leaky" heart valve. For most people with mitral valve prolapse, the cause is unknown. It can be caused by conditions in which cartilage is abnormal (connective tissue…

From the subjective data collected through history taking and objective data gathered from the physical assessment of Mr Jones, the primary differential diagnosis was AR. The left ventricle in AR is typically dilated from secondary to severe volume overload, normally the left ventricle handles both the forward flow delivered from the left atria as well as the backflow of blood from the aorta. The abnormal backflow of blood leads to pathologic changes in the heart in order to compensate for…

Response # 2 Hello Tracie Eilerman, Great post on x-ray # 1. This is actually a difficult one especially for someone with limited knowledge. I concur with you that it is essential for the advanced nurse practitioner to be skillful to discern amongst normal and aberration chest image. While the x-ray # 1 depicted aberration, understanding the patient’s symptomatic physiology in vital to aid necessary clue for prompt medical intervention. The chest x-ray #1 depicts a patient undergoing…

A company called Butterfly Network won clearance from the US Food and Drug Administration for the Butterfly iQ, a portable ultrasound system. The scanning system consists of a portable transducer or probe, a device that converts one energy to another, which connects to an iPhone, and an iOS app to display the images and control the settings. Butterfly iQ has an ultra-wideband matrix array that enables three different transducers to be used. It allows clinicians to perform various scans that can…

Monochrome image as 2-D function Imaging models We look at various imaging models available in field of medicine from Radiography to Echocardiography, their advantages and disadvantages, and applications. Radiography After the discovery of X-rays, Radiography came into limelight. Earlier to the discovery of X-rays also Radiography was available, but electromagnetic spectrum utilised for…

MITRAL STENOSIS Mitral stenosis is the narrowing of inlet valve into the left ventricle leading to an obstruction of inflow of blood from left atrium to the left ventricle during diastole. HEMODYNAMICS: Fibrosis of mitral ring, commissural adhesions and contracture of valve leaflets result in mitral stenosis. Due to the obstruction caused by the mitral stenosis left atrial pressure increases, which results in hypertrophy of left atrium. Increased left atrial pressurein turn increases pulmonary…

his arrival to the hospital, his temperature was 38.5 degrees celsius, heart rate was 98 bpm, and his blood pressure fell in the normal range at 100/80 mmHg. The man’s breathing sounded normal and a systolic murmur was found. Transesophageal echocardiography showed the man’s bicuspid valve with small vegetation that was attached to the ventricular leaflet. There was also a grade 2 aortic regurgitation and an 8mm aortic ring abscess. They also took blood samples, and decided to start…

electrocardiogram, or EKG/ECG, will assess heart rate, and rhythm, while the chest x-ray looks at the size of the heart and affirms the presence of fluid. The most recommended test in diagnosing CHF would be an echocardiography that assess the anatomy and function of the heart. An echocardiography also evaluates blood flow, heart valves, cardiac muscles, and measures the ejection fraction . Prognosis regarding those individuals…
