Our cardiologists perform minimally invasive procedures to improve heart function. Using endovascular procedures, blocked arteries are opened to restore blood flow and improve circulation. Our interventional cardiologists are on-call at St. Elizabeth and Mercy Hospitals providing time sensitive treatments for unstable angina and heart attack. If you have a heart rhythm disorder, we work closely with specialists who treat atrial fibrillation (AFib) and other arrhythmias.
