Cardiac Catheterization


When making an accurate diagnosis must rely on more invasive procedures. Weill Cornell's cardiac catheterization laboratories offer coronary angiography. This procedure provides a detailed evaluation of the extent of blockages in the coronary arteries as well as intravascular and intracoronary ultrasound, in which detailed images of the heart and coronary arteries are created using sound waves.


Angioplasty and Stenting

Cardiac catheterization coupled with angioplasty can be used to re-open arteries that have become blocked by atherosclerotic plaques. This method is used to clear plaque from coronary arteries, arteries in the leg, and from the carotid arteries that supply the brain. In many cases, a stent is inserted to support the walls of the artery, thereby ensuring improved blood flow.



Electrophysiology Diagnostic Studies

For patients with arrhythmias, electrophysiologic studies can be used to determine the part of the heart that is causing the abnormal rhythm, and which treatments work best to return that rhythm to normal. The test involves placing temporary electrode catheters into blood vessels, typically in the groin, then guiding them into the heart.


Catheter Ablation for Arrhythmias

Physicians can often cure arrhythmias by interrupting the path of the electrical impulses that produce them, a technique called ablation. Weill Cornell Cardiologists can treat both supraventricular arrhythmias (including atrial fibrillation) and ventricular arrhythmias as part of a catheter procedure.


Clinical Cardiology

The clinical cardiology service at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, one of the largest medical centers in New York City, provides expert general cardiology care. Among our services, we include

  • Two locations to provide outpatient care for our patients, including a new state-of-the-art facility across from NewYork-Presbyterian/Weill Cornell.
  • On-site echocardiography facilities
  • A pacemaker and defibrillator clinic
  • A periperal vascular clinic for the evaluation of blood vessels outside the heart and expert advice on treatment options.


Cardiac Imaging

Physicians at Weill Cornell are using state-of-the-art technology to image the heart and its vessels. With these advanced approaches to heart imaging, we are able to determine how these structures appear, as well as how they function. Our non-invasive imaging services include:

  • Cardiac CT scan, advanced technology that we use to examine coronary arteries for blockages and to predict those at risk for cardiovascular disease.
  • Echocardiography, a noninvasive procedure that produces a graphic image of the heart's movement, valves, and chambers using high-frequency sound waves
  • Magnetic resonance imaging (MRI), which creates high quality images of the heart throughout its pumping cycle.
  • Nuclear imaging techniques such as SPECT (single photon emission computer tomography), positron emission tomography (PET) – performed in collaboration with the Division of Nuclear Medicine, – and MUGA scans, which evaluate not just how organs appear but how well they are functioning.

Valvular Heart Disease

Balloon valvuloplasty is a procedure in which a narrowed heart valve (stenosis) is stretched open without open-heart surgery.


Other Services

Among the other services offered by the Perelman Heart Institute, we include the latest diagnostic and treatment options for:

  • Peripheral Arterial Disease (PAD) and Carotid Artery Disease [More]
  • Adult Congenital Heart Disease [More]
  • Heart Failure [More]
Cardiac rehabilitation services at the Perelman Institute provides 12 weeks of personalized exercise training, nutritional education, and stress management for patients who have had a heart attack, heart surgery, balloon angioplasty, stable angina, or who have a high risk for cardiovascular disase.
