Identify the pertinent clinical questions and the goal of the examination. Recognize significant clinical information and historical facts from the patient and the medical records, which may impact the diagnostic examination.

Select the correct transducer type and frequency for examination(s) being performed. Adjust instrument controls including examination presets, scale size, focal zone(s), overall gain, time gain compensation, and frame rate to optimize image quality. Demonstrate knowledge and understanding of Doppler ultrasound principles, spectral analysis, and color flow imaging relevant to and in the AE specialty. Demonstrate knowledge and understanding of anatomy, physiology, pathology and pathophysiology relevant to and in the AE specialty. Demonstrate the ability to perform sonographic examinations of the appropriate organs and areas of interest according to professional and employing institution protocols relevant to and in the AE specialty. Recognize, identify and document the abnormal sonographic patterns of disease processes, pathology, and pathophysiology of the organs and areas of interest. Modify the scanning protocol based on the sonographic findings and the differential diagnosis relevant to and in the AE specialty. Perform related measurements from sonographic images or data. Utilize appropriate examination recording devices to obtain pertinent documentation of examination findings.

The cardiac index represents cardiac output that has been adjusted to a person's size. Dividing cardiac output by the person's body surface area, or BSA, will provide the cardiac index. Cardiac output correlates better with body surface area than weight. Cardiac output that is expressed per square meter of body surface area is termed cardiac index.

Left Ventricular Ejection Time The time for the ejection of blood from the left ventricle, beginning with aortic valve opening and ending with aortic valve closure.

Mitral valve prolapse is also known as click-murmur syndrome, Barlow's syndrome or floppy valve syndrome. When the heart contracts, part of one or both flaps collapse backward into the left atrium. In some cases, the prolapsed valve lets a small amount of blood leak backward through the valve, which may cause a heart murmur. Oxygen Opening snap Pulmonary Artery Patient Ductus Arteriosus • • • Patent ductus arteriosus (PDA) is a condition in which the ductus arteriosus does not close. The ductus arteriosus is a blood vessel that allows blood to go around the baby's lungs before birth. Soon after the infant is born and the lungs fill with air, the ductus arteriosus is no longer needed. It usually closes in a couple of days after birth. If the vessel doesn't close, it is referred to as a PDA. PDA leads to abnormal blood flow between the aorta and pulmonary artery, two major blood vessels that carry blood from the heart. Pericardial Effusion Pre-Ejection Period The period between ventricular contraction the semilunar valves blood ejection into commences. when the occurs and open and the aorta Pulmonary Hypertension Pulmonic Regurgitation Pulmonic Stenosis Pulmonary Valve (or vein) Premature Ventricular Contraction Peripheral Vascular Disease Pulsed Wave Doppler Flow (Q) Right Atrium Right Atrial Pressure Right Coronary Artery Right Upper Sternal Border Right Ventricle Right Ventricular Hypertrophy Right Ventricular Outflow Tract Right Ventricular Systolic Pressure Sinoatrial Systolic Anterior Motion (SAM) • Systolic anterior motion (SAM) of the mitral valve (MV) can be a lifethreatening condition. The SAM can result in severe left ventricular outflow tract obstruction and/or mitral regurgitation and is associated with an up to 20% risk of sudden death. • Systolic anterior motion (SAM) describes the dynamic movement of the mitral valve (MV) during systole anteriorly towards the left ventricular outflow tract (LVOT). Short Axis View Bicuspid Aortic Valve Subacute Bacterial Endocarditis • Subacute Bacterial Endocarditis (SBE) is a bacterial infection that produces growths on the endocardium (the cells lining the inside of the heart). Subacute bacterial endocarditis usually (but not always) is caused by a type of bacteria; it occurs on damaged valves, and, if untreated, can become fatal within six weeks to a year. Systolic Blood Pressure Stroke Volume Superior Vena Cava Transposition of the Great Vessels Tricuspid Regurgitation Tricuspid Stenosis Tricuspid Valve Umbilical Artery • The umbilical vein is a vein present during fetal development that carries oxygenated blood from the placenta to the growing fetus. Umbilical Vein Ventricular Septal Defect Wolf-Parkinson-White Syndrome • WPW is caused by the presence of an abnormal accessory electrical conduction pathway between the atria and the ventricles. • Electrical signals traveling down this abnormal pathway (known as the bundle of Kent) may stimulate the ventricles to contract prematurely, resulting in a unique type of supraventricular tachycardia referred to as an atrioventricular reciprocating tachycardia. Most cardiac output is reduced because of: Restrictive physiology (Hypertrophy of the ventricles) In the typical 4 chamber view, why can an inter-atrial septum appear so fat? AMYLOID DEPOSITS • Color flow Doppler can demonstrate… – Normal tricuspid regurgitation – Moderate tricuspid regurgitation – Mild tricuspid regurgitation – Hint: Moderate regurgitation on Doppler takes up more than one-half of the chamber Prosthetic mitral valves • Tilting disk • Ball and cage • St. Jude The ball and cage is not put in anymore. (Makes too much noise) They last for 30-40 years, though. Wire on the image? Probably a pace-maker wire Q: One of the best features of the ball and cage prosthetic valve is: A. B. C. D. A.
