Nuclear Stress Testing
A nuclear stress test is an imaging method that uses radioactive material to show how well blood flows into the heart muscle while at rest and during activity.
Learn MoreOff-Pump Coronary Artery Bypass Surgery (OPCAB)
Coronary artery bypass surgery is traditionally performed with cardiopulmonary bypass. The heart-lung machine allows the heart to be stopped, so that the surgeon can operate on a surface which is blood-free and still. The heart-lung machine maintains life despite the lack of a heartbeat, removing carbon dioxide from the blood and replacing it with oxygen before…
Learn MoreOtoacoustic Emissions Test
This test evaluates the functioning of the outer hair cells in the inner ear. Otoacoustic emissions are acoustic signals generated by the normal inner ear, either in the absence of acoustic stimulation or in response to acoustic stimulation. These emissions can be measured by placing a microphone in the opening of the ear canal and…
Learn MorePacemakers
A pacemaker is a small, battery-operated device that senses when the heart is beating irregularly or too slowly. It then sends a signal to the heart that makes it beat at the correct pace. The procedure to implant a pacemaker does not require open heart surgery, and most patients go home within 24 hours. Before the surgery, medication may…

A pediatric echocardiogram is a test performed on children that uses sound waves to create pictures of the heart. It is used to help diagnose defects of the heart that are present at birth. This test is done to examine the function, heart valves, major blood vessels, and chambers of a child’s heart from outside…
Learn MorePercutaneous Endovascular Abdominal Aortic Aneurysm Repair (PEVAR)
An aortic aneurysm is when a part of this artery becomes enlarged or balloons outward. It occurs due to weakness in the wall of the artery. PEVAR is a fully percutaneous procedure to repair abdominal aortic aneurysms and is done when the aneurysm is very large, growing quickly, or is leaking or bleeding. PEVAR has a…
Learn MorePulmonary Function Studies
Lung function tests, also called pulmonary function studies, include a variety of tests that check how well the lungs work. Tests include: Spirometry – measures the amount of air the lungs can hold and how forcefully one can empty air from the lungs Lung Volume Testing – measures the volume of air in the lungs,…
Learn MorePulmonary Resections
Pulmonary resection is a minimally-invasive thoracic surgery procedure to remove part or the entire lung. Types of resection include: Wedge Resection – surgery to remove a triangle-shaped slice of tissue Segmentectomy – surgery to remove a section of a lobe of lung Lobectomy – surgery to remove one lobe of the lung Bilobectomy – surgery…
Learn MorePulse Volume Recordings
A pulse volume recording (PVR) study is a noninvasive vascular test in which blood pressure cuffs and a hand-held ultrasound device are used to obtain information about arterial blood flow in the arms and legs. This test is done to diagnose peripheral artery disease. There are several types of PVRs, including: Ankle Brachial Index (ABI)…
