Cardiac Interventions in Hackensack, NJ
A cardiac event can be a frightening experience, but with the right interventional cardiologist on your side, there is a clear path forward. Cardiac interventions are minimally invasive procedures used to diagnose and treat blockages, narrowing, and other conditions affecting the heart and its blood vessels. Rather than open-heart surgery, these procedures are typically performed through a small catheter, allowing for faster recovery times and less discomfort.

Coronary Stenting & Heart Catheterization at ACI
Cardiac Intervention Services at ACI
Dr. Nia specializes in two of the most common and effective cardiac intervention procedures: coronary stenting and heart catheterization. Together, these procedures allow our team to both diagnose and treat cardiovascular conditions with precision and care.
Coronary Stenting
Coronary stenting is a minimally invasive procedure used to open narrowed or blocked coronary arteries: the vessels that supply blood to the heart muscle. During the procedure, a small mesh tube called a stent is inserted into the affected artery to hold it open and restore healthy blood flow. Coronary stenting is often performed in conjunction with a heart catheterization and is one of the most effective treatments available for heart blockage. At ACI, Dr. Nia brings extensive experience in coronary stenting, with a track record of delivering outstanding outcomes for his patients.
Heart Catheterization
A heart catheterization — also known as a cardiac catheterization — is a diagnostic and therapeutic procedure in which a thin, flexible tube is guided through a blood vessel to the heart. It allows Dr. Nia to:
- Visualize the coronary arteries and identify blockages or narrowing
- Measure blood pressure and oxygen levels within the heart
- Assess the overall function of the heart and its valves
- Perform interventions such as coronary stenting when needed
Heart catheterizations are performed at an affiliated hospital facility, and Dr. Nia will walk you through exactly what to expect before, during, and after your procedure.
What to Expect From a Cardiac Catheterization Procedure
What Is a Cardiac Catheterization?
A cardiac catheterization procedure begins with the insertion of a thin, flexible tube — called a catheter — into a blood vessel, typically in the wrist or groin. The catheter is then carefully guided to the heart under X-ray imaging guidance. Once in place, Dr. Nia can inject contrast dye to visualize the coronary arteries, measure pressures, and evaluate heart function in real time.
Here is what most patients can expect:
- Before the procedure: You will be asked to fast for several hours and may need to temporarily stop certain medications. Dr. Nia's team will provide detailed preparation instructions.
- During the procedure: You will be awake but sedated. Most patients feel little to no discomfort. The procedure typically takes between 30 minutes and one hour, though this may vary depending on whether an intervention such as stenting is performed.
- After the procedure: You will be monitored for a period of time before being discharged. Most patients return to normal activity within a few days.
Dr. Nia is known for taking the time to answer his patients' questions and explain every step of the process, so you can feel confident and informed going into your procedure.
Frequently Asked Questions
What Are the Risks of a Cardiac Catheterization?
Cardiac catheterization is considered a safe and well-established procedure, but as with any medical intervention, there are some risks to be aware of. These may include:
- Bruising or minor bleeding at the catheter insertion site
- Allergic reaction to the contrast dye
- Rare complications such as blood clots, infection, or irregular heart rhythm
Dr. Nia will review your full medical history and discuss any individual risk factors with you prior to your procedure. His goal is always to ensure you are fully informed and comfortable before moving forward with any treatment.
How Long Does a Cardiac Catheterization Take?
A cardiac catheterization procedure typically takes between 30 minutes and one hour. If a coronary stent is placed during the same procedure, it may take a bit longer. Dr. Nia and his team will give you a clear expectation of timing based on your specific situation so you can plan accordingly.
What Is the Difference Between Interventional Cardiology and General Cardiology?
General cardiologists diagnose and manage heart conditions using medications, lifestyle changes, and monitoring. Interventional cardiologists like Dr. Nia have advanced training in catheter-based procedures that allow them to physically treat blockages and structural heart problems, often without the need for open-heart surgery. ACI offers both general and interventional consultations, so patients receive comprehensive cardiovascular care all in one place.
