Coronary Artery Stenting Baytown

A Coronary Stent is a small expandable tube shaped device used to open narrowed coronary arteries that have interrupted blood and oxygen supply to the muscle of the heart.

Coronary arteries are like small pipes and coronary artery disease (CAD) happens when these arteries get narrower due to fatty material or plaque build up inside. Over the years, as the plaque build up continues, significant blockage of the artery (70 percent or more) can develop. This may cause tchest pain, known as ‘Angina’.

A minimally invasive stenting procedure may be performed to open up narrowed arteries. It does not require general anesthesia.

To begin this procedure, an angiogram is performed to visualize narrowed arteries. A needle is placed in an artery and a guide wire is inserted followed by a catheter which is advanced to a coronay artery. Contrast dye is then injected through the catheter. X-ray movies are taken to reveal the position and severity of narrowed area.

Following the angiogram, another guide wire is passed to the site of narrowing. A deflated balloon catheter is inserted over the guide wire. The balloon is inflated to open the narrowed artery and restore blood flow. This is called a balloon angioplasty.

To keep the artery open after the balloon angioplasty a coronary stent is put in place. A balloon catheter with a collapsed stent is inserted and is inflated to open the stent. The wire and catheter are removed and the stent remains in place to keep the artery open.
