Left Heart Catheterization (LHC)

Designed to help evaluate the heart’s functioning as well as certain heart defects and valve problems, this procedure typically lasts under a few hours. The test involves threading a slender and flexible tube into the left side of the patient’s heart and injecting a safe dye, allowing our cardiologists to see whether there are any blockages. Patients about to undergo left heart catheterization should not eat or drink for 8 hours prior to the test, and though patients will not be under general anesthesia, they will be given local anesthetics and do not feel any pain or discomfort from the insertion of the catheter.

Right Heart Catheterization (RHC)

Also known as pulmonary artery catheterization or Swan-Ganz catheterization, right heart catheterization is the guiding of a thin catheter up to the right side of the heart and into the pulmonary arteries. The catheter is then left in place to allow cardiologists to see how well the heart is working and measure blood pressure in these areas. The test is most commonly used to evaluate patients with low blood pressure, kidney abnormalities, or water in the lungs. The procedure can be performed on an outpatient basis, and most patients are able to return home a few hours after having RHC. The test does not require general anesthesia.

IVC Filter

An inferior vena cava (or IVC) filter is a device implanted into the inferior vena cava, a large vein that carries blood from the body into the heart’s right atrium. The tiny filter is inserted into the vein as a way to prevent a pulmonary embolism – a blockage of the arteries of the lungs caused by air or fat in the blood vessels. The procedure requires only local anesthetic, and most patients are able to resume normal activities within 24 hours.

IVC Removal

Inferior vena cava (IVC) filters come in two varieties: one that is intended for permanent placement and another that should be removed as soon as the patient’s risk of pulmonary embolism subsides. There are a number of risks — including damage or perforation of the blood vessel — if an IVC filter intended for short-term use is left in place for longer than the intended time period. IVC removal, retrieval, or realignment is a fairly fast procedure and patients can resume regular activities shortly after the device is removed.

Carotid Angiogram/Stent

The carotid arteries, which are located on either side of the neck and supply blood to the brain, are also susceptible to plaque buildup and atherosclerosis. A carotid angiogram can help determine the level of plaque buildup in a patient’s carotid arteries (and their risk for stroke), and carotid stenting can help reduce the risk of a blood clot by inserting a small tube in the artery to hold it open. Patients may be required to follow a medication and diet regimen before the procedure and should consult their physicians about appropriate care.

Peripheral Angiogram

Also called a peripheral arteriogram, a peripheral angiogram is a test that helps cardiologists see blockages in the arteries in the legs by using x-rays. Arterial blockages in the lower half of the body are often related to peripheral artery disease (or PAD), a condition that causes pain or tiredness in the legs. Most patients stay in a recovery room for several hours following the procedure, but can return home later that day. Patients may need to adjust their diet, fluid intake, and medications in the days prior to the test and should discuss alterations with their doctor.

Venous Angiogram

Venous angiography is a type of medical imaging that provides cardiologists a picture of the inside of a patient’s blood vessels and heart, allowing them to visualize the path of blood through the body. A thin, flexible catheter is inserted into the body through an artery in the leg, arm, or neck, and cardiologists release a contrast agent to help the blood vessels show up clearly on an x-ray image. The procedure helps diagnose stenosis, or narrowing of the blood vessels.

ICD Implant

An implantable cardio-defibrillator, or ICD implant (also known as a cardiac implantable device or simply a “defibrillator”), is a small electronic device that helps monitor a patient’s heart rate and correct for a sudden, abnormally fast heartbeat. The device may be recommended for patients who have had at least one episode of cardiac arrest, ventricular tachycardia, or ventricular fibrillation. Patients should discuss pre-procedural care and medication intake with their doctors and should not eat or drink the morning of the procedure.


Patent foramen ovale (PFO) and atrial septal defect (ASD) are two congenital conditions affecting the structure of the heart that cause blood to flow through the septum – the wall between the left and right side of the heart. Over time, the conditions can cause the right chambers of the heart to become overloaded with blood and can lead to heart arrhythmia, migraines, and stroke. Openings in the septum can be closed surgically and can reduce the risk of many serious complications.
