cardiac catheterizationOnce your heart and/or vascular problems have been diagnosed, treatment may be needed. This treatment can be limited to prescription medications in some cases, but in others more involved measures are required.

The interventional cardiologists at Cardiology Associates are leaders in the use of catheter-based techniques to open plaque-filled vessels in patients with cardiovascular disease. Our physicians often perform complex procedures on high-risk patients with severe blockages. Our level of specialized expertise does make a difference. Research shows that experienced cardiologists who have performed many angioplasties get better results.



Also known at PTCA (percutaneous coronary angioplasty) or coronary angioplasty this procedure used to treat blockages in the coronary arteries. A catheter is inserted to the point of the blockage where a “balloon” is then dilated (Balloon Angioplasty, also known as PTCA) or a probe generates heat to dissolve a build-up of plaque (Laser Angioplasty).  


Cardiac and Peripheral Vascular Angiography

Procedures performed in the arteries of the heart and extremities to treat blockages using stents, balloons and lasers.



Performed via catheter, a cylindrical, wire mesh device is placed in a blocked vessel to keep it open. At times, devices are needed that emit a drug to help prevent the blockage from recurring (restenosis).



The widening of narrowed or blocked arteries using a catheter (thin tube) with a specialized instrument to remove plaque and open the vessels so that blood can flow in the affected artery.



A pumping device used to assist in initiating life-saving cardiac interventions to critically ill patients who are at high risk. The pump temporarily augments the heart’s pumping function, extending percutaneous interventional therapy (PCI) to patients who may be otherwise denied life saving cardiovascular procedures.


Carotid Stent

Similar to the coronary stent, however, this stenting procedure opens the carotid artery allowing for crucial blood flow to the brain to prevent or treat a stroke.


Peripheral Stent

Procedure to treat Peripheral Artery Disease (PAD) to open blockages and increase blood flow to areas in the legs and other vessels outside of the heart, such as the renal artery leading to the kidneys.



An interventional procedure to treat deep vein thrombosis (DVT) that places temporary balloons on either side of a blockage so that the clot blocking the artery can be eliminated using localized drug therapy and vibration.


Percutaneous Valve Replacement

An alternative to open-heart valve replacement for patients with severe aortic stenosis, the aortic valve is replaced in a minimally invasive procedure deploying a valve replacement via catheter. This procedure is also known at Transcatheter Aortic Valve, TAVR, replacement or Transcatheter Aortic Valve Intervention, TAVI..  Visit for additional information.


Transcatheter Closures

Procedure performed via catheter to permanently close a heart defect such as a hole in the heart or for patients with Atrial Septal Defects (ASD) or Patent Forum Ovale (PFO).


Electrophysiologic Studies

Studies conducted to identify the location of the heart’s electrical pathways. Electrical wires are inserted into a catheter and guided through blood vessels in your groin or arm to your heart. While inside the chambers of the heart, the wires record abnormal impulses or heart beats.


Implantable Cardiac Defibrillator (ICD)

A small electronic device about the size of a deck of cards, once implanted, it constantly monitors your heart rhythm. If it senses a dangerous rapid heart rhythm, it delivers pulses or shocks to the heart and restores a normal rhythm. ICDs continuously monitor the heart rhythm, automatically function as pacemakers for heart rates that are too slow, and deliver life-saving shocks if a dangerous fast heart rhythm is detected.



A small battery-operated device that “paces” the heart rate. Pacemakers monitor and regulate the rhythm of the heart and transmit electrical impulses to stimulate the heart if it is beating too slowly.


Radiofrequency Catheter Ablation

A procedure used to treat some types of rapid heart beating. A catheter with an electrode at its tip is guided to the area of heart muscle where there is an extra pathway and a mild, painless radiofrequency energy is transmitted to the pathway. This causes the heart muscle cells in a very small area to die, which stops the area from conducting the extra impulses that causes the heart to beat too rapidly.
