Cardiac Catheterization Laboratory

If you think you are having a heart attack, do not wait—call 911 now. Do not attempt to drive yourself to the hospital.

At our full-service Cardiac Catheterization Laboratories of NewYork-Presbyterian/Columbia University Irving Medical Center, ColumbiaDoctors, and NewYork-Presbyterian Medical Group Westchester perform emergency and elective angioplasty to unblock clogged heart arteries, in addition to other minimally invasive interventional heart procedures. Our 24/7 catheterization labs are one of the few centers in Westchester County licensed to perform emergency cardiac angioplasty and treat acute myocardial infarctions (heart attacks).

An Experienced Cardiac Catheterization Team


In addition to interventional cardiologists, the Cath Labs are staffed by highly trained and specialized nurses, physician assistants, and angioplasty and electrophysiology specialists. Our team performs about 150 procedures every month, making us one of the most experienced catheterization labs in Westchester County.

Speedy Door-to-Balloon Time

The time between the arrival of a patient in the emergency room for treatment of a heart attack and insertion of a clot-busting balloon during angioplasty is called the door-to-balloon time. Nationally, it is advised that the door-to-balloon time not exceed 90 minutes, ensuring a patient’s best chance of survival. At NewYork-Presbyterian Lawrence, our door-to-balloon time is 60 minutes — well below the national benchmark. This achievement is a direct reflection of the collaboration between our emergency and Cath Lab teams, leading to excellent quality measures and patient outcomes.

When Every Minute Counts

We adhere to the American Heart Association’s “Mission: Lifeline” guidelines and use of the LIFENET® System, which emergency medical personnel use to wirelessly transmit a patient's data from the ambulance to our hospital. We can evaluate these data before the patient arrives and have everything in place when the ambulance pulls in, speeding the delivery of lifesaving cardiac care. Moreover, the Catheterization Labs are located upstairs from the emergency room, saving precious minutes for a patient who may be having a heart attack.

Cardiac Catheterization Procedures

We perform the following catheterization procedures at NewYork-Presbyterian Lawrence:

Balloon angioplasty

During balloon angioplasty, a thin tube (catheter) is inserted into an artery in your groin or wrist. The doctor passes a tiny balloon through the catheter and guides it to the narrowed area in a heart’s blood vessel, where the balloon is expanded to stretch the artery open and restore blood flow.

Stent placement

Most people having balloon angioplasty have a small metal mesh tube called a stent inserted and expanded in the newly opened artery. The stent is left in place permanently as a scaffold to support the artery and maintain blood flow. We use the latest in stent technology, including drug-coated stents whenever possible to reduce the risk of another blockage developing in the artery.

Pacemaker insertion

This device is implanted in your chest to ensure your heart beats at a normal rate. You may be referred for a pacemaker if you have had a low heart rate or fainting spells.

Implantable cardioverter defibrillators (ICDs)

This device is implanted in the chest for continuous heart rhythm monitoring. If a life-threatening arrhythmia is detected, the device will deliver a shock to restore a normal heartbeat.

Biventricular pacemakers

We offer biventricular pacemakers and defibrillators to resynchronize the beating of the heart in people with congestive heart failure whose heart contractions have fallen out of sync ("cardiac resynchronization therapy" or CRT).

Implantable loop recorder

These devices can be implanted in the chest to help analyze a patient's abnormal heart rhythms over several years, and are able to transmit the information back to the physician or other healthcare professionals. These devices do not require the implantation of a wire but analyze the rhythm by measuring the heart's electrical signals from under the skin.

Right heart catheterization

A special catheter (small hollow tube) is inserted into the right side of your heart and measures the pressure inside your heart and lungs.

Direct current cardioversion (cardioversion/DCCV)

If you have a history of atrial fibrillation or atrial flutter (irregular heartbeat), this procedure is used to convert your heart to a normal rhythm using electrical cardioversion.

Atrial septal defect (ASD) or patent foramen ovale (PFO)

These are openings between the upper chambers of the heart that normally close soon after birth. If the ASD/PFO remains open, a small device is placed into the heart to permanently repair the defect. This is done through a minimally invasive catheter-based technique, which is typically performed within one hour.

Peripheral interventions

Including abdominal aortic aneurysm without open surgery 

Acute stroke endovascular therapy with clot extraction
