Cardiology Procedures & Treatments
Cardiac Imaging
Cardiac imaging involves using advanced technology to create detailed images of the heart. These imaging tests help our specialists diagnose heart conditions, assess function, and guide treatment plans. Examples include:
- Echocardiogram
- Cardiac computed tomography (CT)
- Nuclear stress test
- Nuclear treadmill test
- Atrial/Venous ultrasound
- Cardiac MRI
Electrophysiology
Electrophysiology focuses on diagnosing and treating heart rhythm disorders (arrhythmias) by studying the heart’s electrical activity. Electrophysiology procedures help pinpoint irregular electrical signals in the heart and restore normal rhythm through interventions. Common examples include:
- Electrocardiogram (EKG/ECG)
- EP Study (Physicians perform this procedure at Fort Sanders Regional Medical Center)
- Catheter Ablation (Physicians perform this procedure at Fort Sanders Regional Medical Center)
- Tilt Table Testing
- Event Monitoring/Recording
Interventional Cardiology
Interventional cardiology involves minimally invasive procedures using catheters to diagnose and treat heart and blood vessel conditions without open-heart surgery. These techniques are often used to restore blood flow, repair structural issues or treat valve disorders.
- Interventional Cardiac Stenting (Physicians perform this procedure at Fort Sanders Regional Medical Center)
- Patent Foramen Ovale Closure (PFO) (Physicians perform this procedure at Fort Sanders Regional Medical Center)
- Percutaneous Coronary Intervention (PCI) (Physicians perform this procedure at Fort Sanders Regional Medical Center)
Structural Cardiology
Structural cardiology focuses on diagnosing and treating defects or abnormalities in the heart’s structure, including valves, chambers, and blood vessels. Treatment often involves minimally invasive procedures, such as valve repair or closure of congenital heart defects, to improve heart function and patient outcomes. Structural cardiology procedures are performed at Parkwest Medical Center and include:
- MitraClip Procedures (Physicians perform this procedure at Parkwest Medical Center starting Aug. 2025)
- Transcatheter Aortic Valve Replacement (TAVR) (Physicians perform this procedure at Parkwest Medical Center starting Aug. 2025)
