We have locations throughout Manhattan, Brooklyn, and Long Island.
At NYU Langone, our interventional cardiologists provide minimally invasive, catheter-based techniques to prevent, diagnose, and treat cardiovascular disease, including coronary artery disease, peripheral artery disease, and heart valve disease. We also provide emergency treatment for people experiencing life-threatening events, such as heart attack.
Innovation in Heart Disease Care
Our doctors lead research into next-generation stent technology and improving our understanding and management of heart disease.
Learn About Our Cardiology ResearchDuring cardiac catheterization, our specialists guide a long, hollow tube called a catheter through a vessel in the groin or the arm to reach the vessels of the heart. The catheter allows interventional cardiologists to use special tools to look for blocked arteries and, when necessary, perform procedures to restore healthy blood flow.
Our interventional cardiology team performs all procedures and techniques to diagnose and open blocked arteries. We are also known for providing effective therapy for people with complex and complete blockages, including chronic total occlusion, and those who have been told they are not candidates for treatment at other catheterization laboratories.
A coronary angiogram is a diagnostic test used to look for blocked arteries or structural problems in the heart, such as valve disease. This is often done in response to symptoms such as chest pain or abnormal stress test results.
During an angiogram, your doctor uses a catheter to introduce a dye into the bloodstream. An X-ray machine detects the dye and creates a series of images that allow your doctor to look for blockages or other abnormalities.
Our doctors also have expertise in physiological testing, a procedure that uses specialized wires to measure the pressure across a blockage to determine if it needs to be treated. Based on these test results, your doctor may recommend specific treatment, such as stenting to open blockages and restore normal blood flow.
Coronary artery stenting is a technique used to treat blocked arteries. During the stenting procedure, a balloon catheter is inflated at the location of the blockage, opening the artery and allowing blood to flow normally. This is followed by placement of a stent, which is a medicated, scaffold-like mesh tube that reduces the risk of the blockage recurring. Coronary stenting is also done in emergency situations such as a heart attack.
Our interventional cardiologists provide treatment for the most complex, high-risk blockages such as chronic total occlusion, or when arteries have been completely blocked for three months or longer.
We use the most advanced tools and technology to treat challenging blockages. This includes atherectomy, which uses a small tool to cut through blockages; excimer laser coronary angioplasty, which uses laser mechanisms to break up plaque; and intravascular lithotripsy, which uses shock waves to treat the most-resistant blockages.
Our doctors also use catheterization techniques to look for blockages in the peripheral arteries. These blood vessels provide blood flow outside the heart, such as in the legs, intestines, kidney, and neck.
When blood flow in the peripheral arteries that bring blood to the internal organs and extremities is restricted, that loss of circulation causes pain, sores, and, in some cases, life-threatening conditions. Our interventional cardiologists use advanced techniques, including atherectomy, medicated balloons and stents, and lithotripsy, to open clogged arteries and remove these blockages.
These techniques are used to treat chronic high blood pressure caused by kidney blockages; erectile dysfunction caused by limited arterial blood flow; carotid artery disease that increases the risk of stroke; and lower extremity arterial disease, which limits circulation in the legs and increases the risk of gangrene, when tissue dies due to lack of oxygen and blood flow.
To provide the fastest care to people experiencing life-threatening coronary blockages that are causing a heart attack, our catheterization laboratory locations are staffed by a trained interventional cardiology team. We coordinate with paramedics so that we are prepared to bring the patient in for emergency catheterization as soon as they arrive. This approach allows us to deliver treatment as quickly and safely as possible to people who need immediate coronary intervention.
We provide cardiac catheterization at the following laboratory locations:
We care for patients who are experiencing heart attacks or other cardiac events at the emergency departments at Tisch Hospital, NYU Langone Hospital—Brooklyn, NYU Langone Hospital—Long Island, and NYU Langone Health—Cobble Hill Emergency Department at the Joseph S. and Diane H. Steinberg Ambulatory Care Center.
Routine and scheduled catheterizations are coordinated by your referring physician, who helps you make an appointment.
