Interventional Cardiology
In some cases, heart disease can be treated using minimally invasive interventional cardiology techniques that use a catheter (thin, flexible tube) inserted into the arteries. The catheter is guided to the heart to open blocked arteries and improve blood flow. These techniques are performed on an outpatient basis and offer a non-surgical alternative to treat many heart conditions.
Board-certified interventional cardiologists at Tennova Healthcare - Clarksville use a variety of catheter-assisted techniques to treat heart disease, including:
-
Diagnostic cardiac catheterization - Examines the heart with real-time images (fluoroscopy), and measures blood pressure, blood flow, oxygen levels, and is used to collect biopsies and blood samples.
-
Angioplasty - A tiny balloon on the end of a catheter is inflated to push plaque against the wall of the artery to improve blood flow. A laser can also be used to break up the plaque.
-
Stent placement - A stent, which is a small mesh tube, is placed in an artery to hold it open and improve blood flow.
-
Ablation - A catheter fitted with a tiny electrode eliminates abnormal heart cells that cause arrhythmias.
-
Coronary atherectomy - A catheter fitted with a tiny rotating shaver removes hardened plaque to open a blocked artery.
- Chronic total occlusion - Intervention for heart artery blockages that are completely closed.
Structural Heart Disease Interventions
- TAVR is a minimally invasive procedure to replace the aortic valve for aortic stenosis without open heart surgery.
- Balloon valvuloplasty is used in treating aortic and rheumatic mitral stenosis with minimally invasive techniques.
- ASD and VSD repair to close holes in the heart with minimally invasive techniques.
- Paravalvular leak repair to repair leaking prosthetic heart valves without traditional surgery.
When open-heart surgery offers the best treatment solution, board-certified cardiovascular and thoracic surgeons perform advanced procedures such as coronary artery bypass surgery, coronary artery bypass grafting (CABG), congenital heart disease repair and valve repair and replacement.
