Hospital Procedures


Implantation Pacemakers and Defibrillators
A pacemaker (or artificial pacemaker, so as not to be confused with the heart's natural pacemaker) is a medical device which uses electrical impulses, delivered by electrodes contracting the heart muscles, to regulate the beating of the heart.

Overdrive Pacing for Tachycardia Therapy
Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate.[1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults.[1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).

Thrombolytic Infusion
Thrombolysis is the breakdown (lysis) of blood clots formed in blood vessels, using drugs. Ultrasound can also be used in combination with thrombolytic drugs. One such procedure is known as ultrasound accelerated thrombolysis,[1] and another is ultrasound assisted thrombolysis. For the treatment of a massive pulmonary embolism, a review has found catheter-directed therapy to be a safer and effective alternative to systemic thrombolysis. Read More

Pulmonary Catheter Placement Swan-Ganz
In medicine pulmonary artery catheterization (PAC) is the insertion of a catheter into a pulmonary artery. Its purpose is diagnostic; it is used to detect heart failure or sepsis, monitor therapy, and evaluate the effects of drugs. The pulmonary artery catheter allows direct, simultaneous measurement of pressures in the right atrium, right ventricle, pulmonary artery, and the filling pressure ("wedge" pressure) of the left atrium. Read More

Venous Cut down
Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used to get vascular access in trauma and hypovolemic shock patients when peripheral cannulation is difficult or impossible. The saphenous vein is most commonly used. Read More

Intra-Coronary Ultrasound and Flow Reserve
Intravascular ultrasound (IVUS) is a medical imaging methodology using a specially designed catheter with a miniaturized ultrasound probe attached to the distal end of the catheter. The proximal end of the catheter is attached to computerized ultrasound equipment. Read More

Coronary angiography and intervention
A coronary angiogram is a procedure that uses X-ray imaging to see your heart's blood vessels. The test is generally done to see if there's a restriction in blood flow going to the heart. Read More

Head-up tilt table test
A tilt table test is used to evaluate the cause of unexplained fainting (syncope) Your doctor may recommend a tilt table test if you've had repeated, unexplained episodes of fainting. A tilt table test may also be appropriate to investigate the cause of fainting if you've fainted only once, but another episode would put you at high risk of injury due to your work environment, medical history, age or other factors. Read More

Peripheral angiography and stEnting
Angioplasty is a procedure to open narrowed or blocked blood vessels that supply blood to your legs. Fatty deposits can build up inside the arteries and block blood flow. A stent is a small, metal mesh tube that keeps the artery open. Angioplasty and stent placement are two ways to open blocked peripheral arteries. Read More

Percutaneous Placement of Intra-Aortic Balloon Pump and Management
The Intra-Aortic Balloon Pump (IABP) is a circulatory assist device that is used to support the left ventricle. It is used in patients with a wide range of disorders that cause a low cardiac output.. Read More

Interventions (Cath Lab)
Interventional radiology offers an alternative to open surgical procedures and helps address an array of cardiac and other medical conditions. Interventional radiology uses x-rays, ultrasound, CT scans or other imaging techniques to guide tiny tubes, wires or other very small instruments through small openings in the skin. Read More

Cardioversion (emergency and elective)
Cardioversion is a medical procedure done to restore a normal heart rhythm for people who have certain types of abnormal heartbeats (arrhythmias). Cardioversion is most often done by sending electric shocks to your heart through electrodes placed on your chest. Occasionally, your doctor may perform cardioversion using only medications to restore your heart's rhythm. Read more

Endomyocardial Biopsy
Endomyocardial biopsy (EMB) is a diagnostic procedure mainly to survey the sufficiency of immunosuppressive therapy after cardiac transplantation. Other indications for EMB remain controversial. After insertion of an introducer sheet in Seldinger's technique, four to six biopsies are taken from the right ventricle by fluoroscopic guidance. EMB is a very safe operation with a low complication rate which can be rapidly performed with little inconvenience for the patient if performed by a skilled surgeon. Read More

Vena Cava Filter Insertion
During Inferior Vena Cava (IVC) filter placement, a filtering device is placed within the IVC, a large vein in the abdomen that returns blood from the lower body to the heart. Blood clots in the veins of the legs and pelvis can occasionally travel to the lungs where they may cause a pulmonary embolism or blockage. IVC filters help reduce the risk of pulmonary embolism by trapping large clots and preventing them from reaching the heart and lungs. They have a high rate of success in patients who don’t respond to or cannot be given conventional medical therapy. Read More

Tracheal intubation, usually simply referred to as intubation, is the placement of a flexible plastic tube into the trachea (windpipe) to maintain an open airway or to serve as a conduit through which to administer certain drugs. It is frequently performed in critically injured, ill, or anesthetized patients to facilitate ventilation of the lungs, including mechanical ventilation, and to prevent the possibility of asphyxiation or airway obstruction. Read More

Pulmonary angiogram
An angiogram is an X-ray image of the blood vessels. It’s also called an arteriogram. It’s done to look at blood vessels that have problems. A pulmonary angiogram is an angiogram of the blood vessels of the lungs. The procedure is done with a special contrast dye injected into the body’s blood vessels. This is done in the groin or arm. The dye shows up on X-rays. Fluoroscopy is often used during this test. This is like an X-ray “movie.” This lets your healthcare provider clearly see the vessels that send blood to and from the lungs. Read More


Thoracentesis is a procedure to remove fluid from the space between the lungs and the chest wall called the pleural space. It is done with a needle camera.gif (and sometimes a plastic catheter) inserted through the chest wall. Ultrasound pictures are often used to guide the placement of the needle. This pleural fluid may be sent to a lab to determine what may be causing the fluid to build up in the pleural space. Read More

The patient undergoing pericardiocentesis is positioned supine with the head of the bed raised to a 30- to 60-degree angle. This places the heart in proximity to the chest wall for easier insertion of the needle into the pericardial sac. Anatomically, the procedure is carried out under the xiphoid process, up and leftwards. Read More
