It is completely non-invasive and involves no radiation exposure.

Who is the test appropriate for?

An echocardiogram is used if your cardiologist suspects problems with the valves or chambers of your heart, or to evaluate your heart’s pumping efficiency.

Are there any preparations?

There is no preparation for a conventional echocardiogram.

What can you expect during the procedure?

After disrobing from the waist up, you will be given a gown and asked to lie down on an exam table. Electrodes are attached to your chest for an electrocardiogram (ECG) at the same time. The ECG helps with the interpretation of the echocardiogram and evaluating the electrical impulses in the heart. The lights will be dimmed so the technician can see your heart’s image on the screen more clearly. The Doppler echocardiogram uses colors to indicate the varying speed of your blood as it flows through the heart. The technician spreads gel on your chest and then firmly presses the transducer against your skin, aiming the ultrasound beam through your chest. You may be asked to breathe in a certain way or to roll over onto one side. The transducer uses high-frequency sound waves, which are beyond the range of normal hearing. However, you may hear a pulsing “whoosh” sound, which is the machine’s approximation of blood flowing past the structures in your heart. The computer then uses the information from the transducer and creates images which are displayed on the video monitor. The entire test usually takes less than one hour.

When can I expect the results?

Results will be available once your physician has interpreted the pictures, within 24-48 hours.

Transesophageal Echocardiogram http://www.liheart.org/transesophageal-echocardiogram/ http://www.liheart.org/transesophageal-echocardiogram/#comments Wed, 30 Jun 2010 02:12:29 +0000 http://liheart.org/main_site/?p=93 Read More >>]]> What is a TEE or Transesophageal Echocardiogram?

A Transesophageal Echocardiogram (also called TEE for short) is a test used  to obtain ultrasound pictures of the heart with an instrument that is placed in the esophagus.

What does the test show?

Due to the proximity of the esophagus to the heart, extremely detailed pictures of the heart can be obtained using  ultrasound.  The Transesophageal Echocardiogram (TEE) enables the doctor to visualize the structures, valves and vessels of the heart that cannot be seen by a conventional echocardiogram.  The information obtained from this test is very useful in helping your doctor to diagnose and treat you.

What can I expect during my visit?

Upon your arrival to our Mineola office, you will be asked to sign a consent form.  Our nurse and cardiologist will then fully explain the procedure and answer any question you may have.  To start the test, an IV line will be placed in your arm while your heart rate and blood pressure are monitored.

To make the procedure more comfortable, some medication will be administered to numb your mouth.  You will also begin to feel very relaxed as the sedative takes effect.  The TEE probe will then be placed in the mouth and esophagus by the doctor.

Pictures of the heart will be taken for approximately 10 minutes.  The TEE will then be removed.  Thereafter, you will be monitored for approximately 60-90 minutes.  You should avoid eating or drinking until the numbness in your throat has subsided.   When the sedative has worn off, the results will be explained and  recommendations for treatment made.  Your primary care physician will also receive a copy of the findings.  For safety reasons, we advise you to refrain from driving or operating heavy machinery until the next day.

How do I prepare for this test?

It is important that you do not eat or drink anything for 6 hours before the examination.  Small sips of water are permitted with your morning medications.  If you are taking medications for diabetes, please speak with the physician concerning dosages before the test date.

Before scheduling this test, please let your doctor know immediately if you have had problems with your esophagus in the past or difficulty swallowing, especially solid foods.

Immediately prior to the test, you will receive a small dose of medication with a sedative effect.  Therefore we require that someone be available to provide you with transportation home, as it will not be safe for you to drive.  We will be unable to perform the test unless these arrangements have been made beforehand.  That individual may wait for you, or we can place a call to them when the test is completed.

Sleep Wellness Centers of New York http://www.liheart.org/sleep-wellness-centers-of-new-york/ http://www.liheart.org/sleep-wellness-centers-of-new-york/#comments Wed, 30 Jun 2010 01:01:42 +0000 http://liheart.org/main_site/?p=85 Read More >>]]> The Sleep Wellness Centers of New York is accredited by the American Academy of Sleep Medicine (AASM) and provides patients with the most comprehensive medical care. Our facilities each house four hotel-style bedrooms fully equipped with flat screen TVs, DVD players, and full cable access. The bedrooms have been designed to stimulate a comfortable night’s sleep which results in a more effective sleep study. We have sleep centers in two locations, Mineola, New York and Bellmore, New York. Each facility has two board certified pulmonologists on staff and can accommodate adults and adolescents.

What is Sleep Apnea?

A miserable sleep affects us in many ways. It is not only the tired, lethargic feeling that will result from a poor rest period. The entire body can suffer. Obstructive Sleep Apnea (OSA) and Central Sleep Apnea (CSA) are disorders in which a person stops breathing during sleep, often hundreds of time throughout the night. These episodes cause depletion in oxygen levels as well as changes in blood pressure, heart beat, and brain functions.

OSA is a partial or complete closure of the upper airway. During the day muscles keep the upper airway open. As a person with OSA falls asleep, these muscles relax to a point where the airway collapses and becomes obstructed.

CSA occurs when the brain simply forgets to send the message to breathe for a period of time. It can be associated with neurological conditions as well as heart disease.

Symptoms, Causes and Dangers

Symptoms of OSA/CSA may include:

  • Trouble falling asleep
  • Snoring
  • Excessive sweating
  • Gradual weight gain
  • Headaches upon waking
  • Frequent urination interrupting sleep
  • Sour taste
  • Tingling sensations or restlessness in the legs while you sleep
  • Walking during sleep
  • Difficulty with concentration and/or memory

Causes of OSA/CSA may include:

  • Small upper airway
  • Large neck
  • Recessed chin
  • Obesity
  • Weight Gain/Weight Loss
  • Loss of muscle tone in mouth and throat (due to age or neurologic conditions)
  • Nasal and sinus conditions
  • Post-menopausal factors

Dangers of OSA/CSA may include:

  • Strain on the heart during sleep
  • Increase in blood pressure or heart rate
  • Decrease in oxygen levels
  • Stroke
  • Obesity
  • Abnormal heart rhythms
  • Irritability/Mood swings
  • Depression
  • Abnormal dreaming
  • Frequent urination
  • Acid reflux
  • Decreased quality of life
  • Attention Deficit Disorder (ADD)

If you have experienced any of these symptoms, you may need a sleep study evaluation. Our goal is to help you achieve a restful, regenerative sleep as quickly and safely as possible.

Types of Studies

Types of studies conducted at the Sleep Wellness Centers of New York:

Polysomnogram (PSG) – This is a diagnostic study that measures the quality of a person’s sleep by measuring the body’s involuntary functions during sleep, such as breathing and heartbeat. A typical PSG records brain waves, eye movement, chin muscle tone, heart rate, leg movements, breathing, oxygen levels, and audio/video recording for your safety. In addition, a pulse oximeter will be placed on your finger to measure your oxygen level and heart rate.

What to expect from a PSG sleep study – A PSG study is a non-invasive overnight sleep study. It is performed while the patient is asleep. The patient is set up on electrodes which attach to the head, face, chest, and legs. Two belts will be word around the abdomen and thorax and a nasal cannula is inserted in the nose to measure nasal pressure.

CPAP Titration: CPAP stands for continuous positive airway pressure. Nasal CPAP therapy is a non-invasive, non-surgical way to treat Obstructive Sleep Apnea.

What to expect from a CPAP sleep study – A CPAP study is almost the same procedure as the PSG except a mask will take the place of the nasal cannula. The mask will be fitted properly and is to be worn through out the sleep study. The technician will be monitoring you and will titrate (adjust) your pressure as needed. The CPAP allows the patient to achieve restful and deep sleep without interruption during the night.

Multiple Sleep Latency Test (MLST) – The MLST is a daytime sleep study that measures the patient’s level of daytime sleepiness. It also measures how quickly an dhow often you enter the REM stage during sleep.

What to expect from a MLST sleep study – A MLST sleep study consists of a series of nap opportunities during which sensors and electrodes record data and body functions. This is a non-invasive, painless test.

What to Expect and How to Prepare for Your Study

Please note: A patient is required to sleep at least four hours. An insufficient study will require re-testing.

  • Please make transportation arrangements prior to the sleep study.
  • The sleep study requires video recording of your bedroom the entire night. Technicians will be monitoring patients throughout the night.
  • Please be sure to bring: pajamas, a list of medications, your insurance card, and photo ID.
  • Note: We do not provide toiletries so please be sure to bring all necessities.
  • Please do not bring: alcohol, caffeine, wigs, perfume, moisturizer, and hair pieces. Proper hygiene is required.
  • Patients are allowed to use the shower but must notify the technicians that evening.
  • No food or beverages are allowed at the sleep center unless medically required. Please notify the technician of any conditions.
  • Sleep technicians will wake the patient at 5:00 a.m. In the morning you will be asked to fill out a survey and a post-sleep questionnaire.

When You Will Get Your Results

Results take approximately two weeks. An appointment should be made with the sleep physician to discuss results, treatment options, and see if further testing is necessary.

Is a Sleep Study Covered by Insurance?

Most insurance companies cover this diagnostic test. Co-pays and deductibles may apply. Our staff will contact your insurance company to verify coverage. We accept most insurance plans.

Please note: If you are not covered for a diagnostic sleep study you may call our office to arrange a payment plan.

What is CT Angiography? http://www.liheart.org/what-is-ct-angiography/ http://www.liheart.org/what-is-ct-angiography/#comments Wed, 30 Jun 2010 00:40:02 +0000 http://liheart.org/main_site/?p=77 Read More >>]]> CT (computed tomography) angiography (CTA) is a procedure that uses x-rays to visualize blood flow in arteries and veins throughout the body, from those serving the heart and brain to those bringing blood to the lungs, kidneys, and arms and legs. CT combines the use of x-rays with computerized analysis of the images. A rotating device passes beams of x-rays through the body from several different angles to create cross-sectional images, which are then integrated by computer into a three-dimensional picture.

Compared to catheter angiography, which involves placing a sizable catheter and injecting contrast material into a large artery or vein, CTA is a much less invasive and more patient-friendly procedure. This type of exam has been used to screen large numbers of individuals for heart disease without the need for hospital admission.

What are some common uses of the procedure?

  • Identifying aneurysms in the aorta or in other major blood vessels. (Aneurysms are areas of blood vessel walls that are weakened and bulge out. They are life-threatening because they can rupture.)
  • Identifying dissection in the aorta or its major branches. (Dissection means that the layers of the artery wall peel away from each other, which can be painful and life-threatening.)
  • Detecting arteries in the pelvis or leg which have narrowed.
  • Detecting thrombosis (clots) in veins, for example large veins in the pelvis and legs. These clots may travel to the lungs and cause pulmonary embolism.
  • Examination of the pulmonary arteries in the lungs to rule out pulmonary embolism.
  • Visualizing blood flow in the renal arteries (those supplying the kidneys) in patients with high blood pressure and those with kidney disorders. Also done in prospective kidney donors.
  • Evaluating the effectiveness of a stent, a device used to facilitate blood flow in a diseased artery.

How should I prepare for the procedure?

This test is performed exclusively at our Mineola location. You will be asked to avoid food and drink, smoking, and caffeine for at least 5 hours prior. You will also be asked whether you have asthma or any allergies to foods or drugs, and what medications you are currently taking. If you are pregnant, you should inform the technologist before the procedure. You will be asked to wear a gown and remove any jewelry that might interfere with picture taking.

How does the procedure work?

Before the test begins, a small dose of contrast material is injected into a vein in the arm. During the exam, the rotating device spins around the patient, creating a beam of x-rays, and the detector takes snapshots of the beam after it passes through the patient. The computer processes the images and allows them to be displayed in different ways, for example, in slices, or as three-dimensional “casts” of the blood vessels.

How is the procedure performed?

After changing into a gown you will lie down on a narrow table and have an IV set up. The part of your body to be examined will be placed inside the opening of the CT unit. A test image is taken to determine the best position, and a small dose of contrast material may be given to see how long it takes to reach the area under study.

What will I experience during the procedure?

CTA takes about 10 to 25 minutes from the time the actual examination begins. Overall, you can expect to be in the exam room for 20 to 60 minutes. You may feel warm all over when contrast material is injected, but you will not feel pain. You will be asked to remain as still as possible. Pillows and foam pads are used help make it more comfortable. At the same time, the technologist may use Velcro straps to keep an area of your body from moving. The examination table will move into and out of the scanner opening, and only a small part of your body will be inside at any one time. You may be asked to hold your breath for 10 to 20 seconds. Once the images have been taken, you will be free to leave. You can eat immediately, and drinking plenty of fluids in the hours following the exam is recommended to help flush contrast material out of the system.

Who interprets the results and how do I get them?

Our director of CT scanning will analyze the images and send a report to your primary care physician. Typically the results of CTA are available within 24-48 hours.


CTA can be used to examine blood vessels in many important areas of the body, including the heart, brain, kidneys, pelvis, and the lungs. The procedure is able to detect narrowing of blood vessels so that corrective therapy can be facilitated immediately. This method also displays the anatomical detail of blood vessels more precisely than magnetic resonance imaging (MRI) or ultrasound. Today, CTA can replace conventional catheter angiography in many patients. It is advantageous because it is safer and much less time-consuming than catheter angiography and is a cost-effective procedure. There is also less discomfort for the patient because the contrast material is injected into an arm vein rather than into a large artery in the groin.
