Cardiovascular
During this procedure, a small amount of radioactive substance is injected into the vein. Its progress through the heart is then traced with a special camera to evaluate heart function. Doing this during rest and exercise assists the physician in comparing the differences in heart activity.
A right heart catheterization is performed to determine how well the heart is pumping and to measure the pressures in the heart and lungs.
Right heart catheterization with heart tissue biopsy is a procedure in which tissue samples are taken directly from the heart muscle. This procedure may be done in addition to a right heart cath to see if the heart tissue is normal.
Robotic cardiac surgery is a form of heart surgery performed through tiny incisions in the chest. Thanks to the use of tiny instruments and robotic devices, surgeons are able to perform several types of heart surgery in a way that is much less invasive than other types of heart surgery.
During this procedure, the electrical activity of the heart is monitored over a period of several minutes in order to capture abnormal heartbeats which may occur only intermittently.
This is a diagnostic procedure often used to assess syncope (fainting) by creating changes in posture from lying to standing.
A transesophageal echocardiogram uses sound wave (ultrasound) technology to examine heart function. By inserting a probe with a transducer down the esophagus rather than placing the transducer on the chest, physicians get a clearer image of the heart because the sound waves do not have to pass through skin, muscle, or bone tissue.
Ultrafast CT, or electron-beam computed tomography (EBCT) can take multiple images of the heart within the time of a single heartbeat, and can detect very small amounts of calcium within the heart and the coronary arteries.
During a valvuloplasty, a catheter is threaded through a vein to the heart where a balloon is used to open a stiff valve. Once opened, the balloon and catheter are removed.
Vascular studies use ultrasound (sound wave) technology to assess the flow of blood in arteries and veins in the arms, legs, and neck.
A combination of contrast dye and X-rays are used to visualize the veins in the legs in order to diagnose deep vein thrombosis and other conditions.
