Cardiac Catheterization Services

Interventional Cardiologists from NewYork-Presbyterian Hospital/Columbia University Medical Center routinely perform more than 10,000 cardiac catheterization procedures per year. Now patients at NewYork-Presbyterian Lawrence Hospital can benefit from receiving this same level of cardiac care in the community setting at the newly opened NewYork-Presbyterian Hospital Cardiac Catheterization Laboratory located at our hospital here in Bronxville. NewYork-Presbyterian has the #1 rated heart program in New York State and the #3 rated heart program in the country, according to U.S. News & World Report.

Cath lab team

Staffed by physicians of ColumbiaDoctors, the faculty practice of Columbia University, our full-service cath lab performs emergency and elective angioplasty, as well as minimally invasive procedures to visualize the arteries of the heart, check blood flow and pressure, and evaluate the efficiency of heart valves. The lab is one of the few centers in Westchester County licensed to perform emergency cardiac angioplasty. Patients who may require more advanced cardiac care will have access to physicians at NewYork-Presbyterian/Columbia University Medical Center, thereby ensuring seamless continuity of care.

In addition to performing emergency cardiac angioplasty for patients having a heart attack, our cath lab also offers routine testing like cardiac imaging and angiograms as well as diagnostic tests. Both emergency and elective procedures are performed including stenting to improve heart blood flow or treatment for arrhythmias by implanting pacemakers or defibrillators.

Description of Services

The Cardiac Cath Lab offers a broad spectrum of diagnostic imaging techniques and life-saving treatments that include:

  • Coronary angiogram. A series of X-ray images of your heart arteries are recorded and doctors assess the pictures for narrowing and blockages. Doctors inject dye that is visible by an X-ray machine into a catheter that is inserted through an artery in your groin or wrist. The diagnostic procedure can help your doctor decide if angioplasty, stenting, coronary artery bypass surgery, or medical therapy is needed.
  • Coronary balloon angioplasty. During a coronary angiogram, doctors inflate a small balloon-tipped catheter where your coronary artery has narrowed. The procedure opens up the artery for better blood flow.
  • Coronary stenting. Doctors insert and expand a mesh tube with medication into your narrowed artery wall, allowing blood to flow in your previously blocked artery.
  • Right heart catheterization. Doctors insert a catheter with special sensors into the vein of your groin or neck to determine how well the heart is pumping and to measure pressures in the heart and lungs.
  • Heart biopsy. Doctors insert a catheter into your vein to obtain a small sample of tissue from your heart to be examined under the microscope.
  • Cardiac imaging. An imaging technique that includes a specially designed catheter with ultrasound tips for visualization of the artery wall allows doctors to obtain additional information when evaluating the severity of a narrowed coronary artery.

Our Facility

The Cath Lab is conveniently located upstairs from the emergency room, saving precious minutes for a patient who may be having a heart attack.

We accept most major health insurance plans, as well as Medicare and Medicaid.

Our Team

In addition to Interventional Cardiologists from NewYork-Presbyterian/Columbia, the Cath Lab is staffed by highly trained and specialized cath lab nurses, physician assistants, and angioplasty and electrophysiology specialists.

Doctors urge patients with early warning symptoms to come in for a heart check. However, if you think you are having a heart attack, do not wait—call 911. Do not attempt to drive to the hospital yourself and risk losing precious minutes because early diagnosis and treatment saves lives.
