Services
Cardiac Catheterization
Our cardiac catheterization services diagnose and treat coronary artery disease through minimally invasive procedures. Using advanced imaging technology, we identify blockages and perform interventions like angioplasty and stenting. Patients benefit from reduced recovery times compared to traditional surgery while receiving care from interventional cardiologists with specialized training in complex coronary procedures.
Echocardiography
We offer comprehensive echocardiography services including stress echocardiography and Doppler studies to assess heart function. Our IAC-certified laboratories ensure accurate diagnosis of valvular disease, heart failure, and structural abnormalities. Patients receive timely interpretations from cardiologists with subspecialty training in echocardiography, enabling precise treatment planning.
Nuclear Cardiology
Our nuclear cardiology services include myocardial perfusion imaging to evaluate blood flow to the heart muscle. Using state-of-the-art gamma cameras in IAC-certified facilities, we diagnose coronary artery disease and assess treatment effectiveness. Patients receive radiation safety protocols developed by board-certified specialists in nuclear cardiology for optimal diagnostic accuracy.
Structural Heart Interventions
We specialize in structural heart interventions including TAVR, MitraClip, and closure devices for congenital defects. These minimally invasive procedures treat valvular disease without open-heart surgery. Patients benefit from collaboration with St. Francis Hospital's structural heart program, recognized for innovation in transcatheter valve replacement technologies.
Heart Failure Clinics
Our congestive heart failure clinics provide comprehensive management for patients with advanced heart disease. Services include medication optimization, device monitoring, and lifestyle counseling. Patients receive coordinated care from cardiologists with expertise in heart failure management, reducing hospitalizations through personalized treatment plans and regular follow-up monitoring.

I had a friend that worked here, and they let her go for no good reason. The office manger did even tell her she was being let go. She made someone else do her dirty work. They can't keep good help. She was always there on time and never called out. She cared for her patients. I guess that is not good enough these days. It doesn't pay to go out of your way to help people. She never goes into the office to check on the employees or see how anyone is doing. She hides behind her desk.
