Interventional Cardiology

Interventional cardiology is the cardiology specialty focusing on the diagnosis and treatment of narrowed arteries that supply blood to the heart and throughout the body.

Interventional cardiologists also treat certain other structural heart conditions, using a non-invasive, catheter-based approach. These procedures usually result in less scarring, a shorter hospital stay and faster recovery, and are performed in Cardiac Catheterization Laboratories, or cath labs.

Our expertise

Each year, approximately 3,000 procedures are performed in our cardiac cath labs including diagnostic heart catheterization, balloon angioplasty and stent placement (including cardiac, carotid and peripheral stenting).

We have a team of eight interventional cardiologists, providing inpatient care on our hospital campuses and outpatient care through The Heart Center of NGMC.

Advanced technology and capabilities

The lab at NGMC Gainesville consists of four state-of-the-art procedure rooms, and the lab at NGMC Braselton consists of two. They house the most advanced technology including bi-plane flat panel imaging, which allows for more images with less contrast dye usage, and magnetic catheterization. Northeast Georgia Medical Center (NGMC) is the first hospital in Georgia, and still one of only a handful of programs in the Southeast, with magnetic catheterization technology, a catheter navigation system designed to assist physicians performing interventional procedures with more precision and control, especially in difficult to reach areas of the heart.

Diagnostic and treatment procedures

Diagnostic and treatment procedures performed in the NGMC Cardiac Catheterization Laboratory include:

Alcohol Septal Ablation

This minimally-invasive procedure for treating hypertrophic cardiomyopathy is performed at NGMC Gainesville.

Technique used to remove plaque from a blocked heart artery. These procedures can be completed using several different state-of-the-art methods that the cath lab has readily available.

Cardiac catheterization

Diagnostic procedure completed by gently inserting a catheter into the blood vessels that feed the heart. Several injections of x-ray dye are made into the arteries allowing doctors to see heart blockages. Pressure measurements also are taken inside the heart to further evaluate the heart chambers and valves.

Coronary stenting

A stent is a small metal coil, or mesh tube, that may be placed in the artery to help keep it from reclosing by providing a scaffolding-like support. A stent is commonly used in conjunction with a balloon angioplasty and athrectomies.

Coronary ultrasound

Device which utilizes sound waves to assist in the evaluation of the heart arteries. A small catheter is placed inside the artery, and pictures are taken from within to better define the blockages.

MitraClip procedure

This minimally-invasive treatment option for mitral valve regurgitation is performed at NGMC Gainesville.

Percutaneous transluminal coronary angioplasty

Also known as PTCI or balloon angioplasty, this interventional procedure involves inserting a balloon-tipped catheter into a blocked heart artery. The balloon is then inflated and deflated to compress the blockage of plaque and increase the blood flow.

Peripheral angioplasty

Procedure which examines arteries of the body, i.e. arteries in the leg, for diagnosis and treatment, helping increase the blood flow where needed. Balloons and stents are often used in other arteries outside the heart, including the legs, kidneys and carotid arteries.

Cardiac cath lab procedures require a physician referral and are performed by a cardiologist following an evaluation.

Permanent pacemakers

Procedure that involves the implantation of an electronic device that helps the heart maintain regular beats.

Robotic Angioplasty

When someone needs a stent or balloon to open up blocked arteries, NGMC’s robotic angioplasty capability combines physician expertise with robotic precision to restore blood flow to the heart.

Procedure similar to balloon angioplasty of the heart arteries. The difference is that a larger balloon is used to expand a constricted valve, leading to increased blood flow through the heart.

Service area

The cardiac cath lab at NGMC Gainesville is located on the NGMC Main Campus, on the 4th floor of the Outpatient Services Building. This cardiac cath lab serves not only Hall County, but also 15 other counties in the regional service area, and provides 24-hour, 7-day a week coverage for interventional cardiac care.

The lab at NGMC Braselton is located on the second floor of the hospital and offers people in the Greater Braselton area with the same life-saving treatment for opening blocked arteries to the heart offered at NGMC Gainesville. It also provides 24-hour, 7-day a week coverage for interventional cardiac care.
