Which procedure is known for treating coronary artery disease?

Coronary stenting is a minimally invasive procedure used to treat coronary artery disease (CAD), which is characterized by the narrowing or blockage of the coronary arteries due to atherosclerosis. During this procedure, a stent—a small mesh tube made of metal or polymer—is inserted into the affected artery to keep it open, allowing for improved blood flow to the heart muscle. This is crucial for relieving symptoms of CAD, such as chest pain (angina) and reducing the risk of heart attacks.

The placement of a stent often follows a procedure called angioplasty, where a small balloon is inflated at the site of the blockage to expand the artery. The stent is then positioned to maintain the artery's patency after it has been widened. This intervention is important as it helps restore effective blood flow and can improve overall heart function, significantly impacting the quality of life for patients with coronary artery disease.

In contrast, the other procedures listed do not address coronary artery disease. Adenoidectomy and tonsillectomy are surgical procedures related to the removal of the adenoids and tonsils, respectively, typically performed for chronic infection or obstructive symptoms in the throat. Pressure equalizer tubes, also known as tympanostomy tubes, are used to
