Dr. Zacca offers the spectrum of clinical cardiac services, ranging from nuclear angiography to interventional cardiology.
At the core of each clinical subsection is a devotion to optimizing patient outcomes by bringing highly trained staff, state-of-the-art technology, and cutting edge techniques to the patient suffering from cardiovascular disease.
Some of our services include the following:
Exercise Nuclear Stress Test
Nuclear Stress testing is a form of a treadmill test that may provide added useful information about your prognosis. A radioactive tracer is injected into your blood stream while you exercise on the treadmill. The material is safe and medically approved. Similar materials are used to obtain bone scans, brain scans, thyroid scans etc. The radioactive tracer is taken up by your heart and is distributed through the heart muscle according to blood flow.
Areas of the heart that are supplied by narrowed arteries will have reduced blood flow that will show up on scanning as reduced areas of radioactivity. These techniques are more accurate than routine treadmill testing in finding coronary disease and determining its severity. Nuclear scanning has the added advantage of providing information on the pump function of the heart.
Echocardiography is an ultrasound test that gives excellent pictures of the structures of the heart. It evaluates the size, shape and motion of these structures. Important information may be obtained on the function of the pumping chambers of the heart and of the valves. In conjunction with two dimensional imaging, Cardiac Doppler may be used to find leaky cardiac valves and/or the presence of tightened or stenotic valves.
During the Echocardiogram, a transducer (a small instrument looking something like a stethoscope) coated with conductive jelly will be placed on the chest and moved along the chest wall over the areas to be examined. The test is entirely painless and safe and takes about 20 to 30 minutes. Our echo lab has been accredited by the Intersocietal Commission for the Accreditation of Echocardiography Laboratories, indicating that we meet their stringent benchmarks for quality and service.
Venous Doppler Study
24 Hour Holter Monitor
A Holter monitor is a recording device which is attached to your skin by ECG electrodes. It is able to record the heart rhythm over a 24-hour period. You will record any symptoms that occur during that time. The recording is then downloaded and analyzed.
It may detect changes in heart rhythm, or changes in the ECG that might mean lack of blood supply to the heart.
