Minimally Invasive
Cardiovascular Services
​For the last five years, the physicians at Memorial have performed thousands of lifesaving diagnostic and interventional procedures each year. For patients, these numbers translate into higher quality of care and better outcomes. The advantage to minimally invasive procedures is the decrease in risk, pain, and recovery time. No general anesthesia is required and some procedures can be performed on an outpatient basis.
​Our minimally invasive services include:
Cardiac catheterization

This procedure involves inserting a catheter into an artery, usually in the groin area, to the heart. This has become a primary tool for visualizing the heart and blood vessels to help diagnose and treat heart disease.

Drug-eluting and bare metal stents

This type of stent is made of expandable, metal mesh and placed by balloon catheter at the site of a narrowing artery. The stent is expanded and left in place to keep the artery open.

Carotid angiography

This is an X-ray technique where dye is injected into the carotid arteries that lead to your head. Blood flow and blood pressure are measured in the arteries to check for blockage.

Cardiac and peripheral balloon angiography

An X-ray technique where dye is injected into the chambers of your heart or the arteries that lead to your heart (the coronary arteries). The test lets doctors measure the blood flow and blood pressure in the heart chambers and see if the coronary arteries are blocked.

Cardiac and peripheral stent placement

A stent is a wire metal mesh tube that is collapsed to a small diameter and put over a balloon catheter. It’s then moved into the area of the vein that has blockage. When the balloon is inflated, the stent expands, locks in place, and forms a scaffold. The stent stays in the artery permanently, holds it open, and improves blood flow.

Silverhawk atherectomy

This procedure removes the fatty deposits or blockage in an artery that is narrowed by the buildup of fatty tissue (atherosclerosis).

Thrombolytic therapy

The use of intravenous or intra-arterial medicines to dissolve blood clots in an artery.


This procedure removes a blood clot (thrombus) from a blood vessel.

Dialysis access (via arteriovenous fistula or graft)

A vascular surgeon inserts a fistula (passageway between two vessels that normally do not connect) created for therapeutic reasons like dialysis.

Inferior vena cava filters (IVC filters) for DVT and pulmonary embolism

This involves the placement of filters through the blood vessels. A catheter is guided into the vein then the filter is pushed through and deployed into the desired location.

Cardiac resynchronization therapy
(CRT)/bi-ventricular pacemakers and defibrillators

This procedure involves placing a bi-ventricular pacemaker in your body to get the left and right ventricles of the heart to pump together.

Pacemaker and defibrillator implantation

A surgically implanted electronic device that helps regulate the heartbeat.


This involves a special catheter that is guided into the heart via an insertion point in the groin. The head of the catheter has electrical sensors, which help the cardiologist to guide the catheter to the correct place. Once in place the cardiologist can deliver electrical pulses, which destroy (ablate) the tissue that is causing the heart problem.

Cardiac electrophysiology studies (EPS)

This is a test that uses cardiac catheterization to study patients who have arrhythmias, or abnormal heartbeats. An electrical current stimulates the heart in an effort to provoke an arrhythmia, which is immediately treated with medicine. EPS is used primarily to identify the origin of arrhythmias and to test the effectiveness of medicines used to treat abnormal heart rhythms.

Event loop recorder implants

These are surgically implanted, small devices placed close to the heart. They have the ability to record the electrical activity of the heart and store heart rhythm disturbances. They can be triggered by the patient to store events.
