Cardiac Catheterization Laboratory

Allegiance Health’s three cardiac catheterization (cath) labs provide our community with a range of services, from diagnostic cardiac catheterizations, which identify coronary artery disease, to interventional cardiology, which diagnoses and treats coronary artery disease with non-surgical procedures. Cardiac angioplasty is a procedure that opens an artery blocked by plaque or a blood clot. A blocked artery can lead to a heart attack if the blood supply to the heart is severely reduced or stopped.

Beating National Door-to-Balloon Time Standards

A successful angioplasty program can be measured in door-to-balloon time – the time between your arrival in the Emergency Department and the time you receive an angioplasty procedure. According to the American Heart Association, heart attack patients have a higher survival rate if they receive angioplasty within 90 minutes.

Since July 2006, Allegiance Health has achieved an average door-to-balloon time of 65 minutes, which is consistently better than the nationally recommended standards.

Heart Arrhythmia Services

Allegiance Health diagnoses and treats the various causes of irregular heartbeat (heart arrhythmia) through its electrophysiology lab. Procedures performed here include the pacemaker and cardiac defibrillator implants, as well as catheter ablation, a procedure that destroys tiny sections of heart muscle that are causing a heart rhythm disturbance.

We offer both traditional radiofrequency ablation and a newer method, cryoablation, which uses extremely cold temperatures to disable heart cells. Learn more about cryoablation.


Allegiance Health’s cardiac catheterization team has performed coronary angioplasty on an emergency basis since 2006. We began offering this procedure to patients on an elective outpatient basis in 2008. The cath labs are led by seven interventional cardiologists who have served the community for more than 10 years.

Eating one or two servings of fish rich in Omega-3 fatty acids per week, like salmon or tuna, decreases your risk for heart disease and even heart attack.
