  1. Transesophageal echocardiography

    merge to Transesophageal echocardiogram date October 2010 Transesophageal echocardiography TEEC is a diagnostic procedure that involves feeding a small ultrasound device into a patient s esophagus to evaluate heart function. Since the esophagus is very close to the heart left atrium , there is less noise distortion compared to traditional echocardiography and higher resolution images can be obtained. Indications Transesophageal echocardiography may be used to diagnose heart conditions, assess the overall function of the heart, or evaluate abnormalities of the left atrium. Contraindications Contraindications include previous esophageal surgery, swallowing problems, severe hiatal hernia, previous chest radiation, severe bleeding problems, and severe esophageal ulcers. Procedure The outpatient procedure takes 15 20 minutes and is performed by a cardiologist or an anesthesiologist in an operating room. The patient is under mild to moderate sedation . The patient can start eating and drinking one hour after the procedure or after sedation has subsided. Adverse effects The procedure carries a 1 7,000 1 10,000 risk of esophageal perforation. Other adverse effects include mouth and throat soreness and somnolence from sedation. Category Cardiac imaging Category Medical ultrasound medicine stub Medical imaging ...   more details

  1. Cardiac sonographer

    Cardiac sonographer also known as echocardiographer , or cardiac ultrasound technologist is a medical profession of sonographer s that specialize in the anatomy and function of the heart . It is a technical job that in the USA has traditionally required an Associates degree in Echo and passing a National Registry exam, but more and more often is requiring a Bachelors degree as the field gets more developed and complicated. Much like how a general sonographer would use sonography ultrasound to view a fetus inside a pregnant woman, cardiac sonographers use the same technology to examine and evaluate the heart chamber sizes, arrangement of the parts, muscle function, valve function and blood flow. Cardiac sonographers typically do not make diagnoses, but rather report their results to a cardiologist for further analysis. Educational requirements in U.S. Most schools that offer training for cardiac sonographers have several different programs available to students. Programs that are certificate based can be completed in about twelve 12 months allowing the candidate to make a relatively quick entrance into their chosen career. However, some students may choose to pursue a full four year degree in order to allow them to work at more advanced levels but most commonly, the course of study for those pursuing the cardiac sonographer profession is the two year associate s degree. Typically, an associate s degree satisfies the minimum educational requirement for most employers.

A specialized probe containing an ultrasound transducer at its tip is passed into the patient s esophagus . ref MeshName Transesophageal Echocardiography ref This allows image and Doppler evaluation which can be recorded. It has several advantages and some disadvantages compared to a transthoracic echocardiogram TTE . Advantages The advantage of TEE over TTE is usually clearer images, especially of structures that are difficult to view transthoracicly through the chest wall . The explanation for this is that the heart rests directly upon the esophagus leaving only millimeters that the ultrasound beam has to travel. This reduces the attenuation weakening of the ultrasound signal, generating a stronger return signal, ultimately enhancing image and Doppler quality. Comparatively, transthoracic ultrasound must first traverse skin, fat, ribs and lungs before reflecting off the heart and back to the probe before an image can be created. All these structures, along with the increased distance the beam must travel, weaken the ultrasound signal thus degrading the image and Doppler quality. In adults, several structures can be evaluated and imaged better with the TEE, including the aorta , pulmonary artery, valves of the heart, both atria, atrial septum, left atrial appendage , and coronary arteries . TEE has a very high sensitivity for locating a blood clot inside the left atrium. ref www.heartsite.com ref Disadvantages TEE requires a fasting patient, the patient must follow the ASA NPO guidelines i.e. usually not eat or drink ...   more details

ESV is the lowest volume of blood in the ventricle at any point in the cardiac cycle . The main factors that affect the end systolic volume are afterload and the contractility of the heart. Uses End systolic volume can be used clinically as a measurement of the adequacy of cardiac emptying, related to systolic function. On an electrocardiogram , or ECG , the end systolic volume will be seen at the end of the T wave. Clinically, ESV can be measured using two dimensional echocardiography , MRI magnetic resonance tomography or cardiac CT computed tomography .
