What condition is primarily treated by balloon angioplasty in the cardiac catheterization lab?

• A. Atherosclerotic thickening
• B. Stenotic dissection
• C. Valvular regurgitation
• D. Venous insufficiency

Answer: (A)

Balloon angioplasty is primarily used to treat atherosclerotic thickening in the coronary arteries. Atherosclerosis involves the buildup of fatty deposits, known as plaques, which lead to the narrowing of the arterial lumen and restrict blood flow. During angioplasty, a catheter with an inflatable balloon is inserted into the affected artery and positioned at the site of the blockage. Upon inflation, the balloon expands, compressing the plaque against the artery walls, which helps to restore adequate blood flow to the heart by widening the artery. This procedure is specifically indicated for cases where there is significant atherosclerotic narrowing (stenosis) that poses a risk for heart attack or unstable angina. It is effective in alleviating symptoms of reduced blood flow and improving the functional capacity of patients with coronary artery disease. Other conditions listed, such as stenotic dissection or valvular regurgitation, would typically require different interventions, such as surgical repair or replacement, while venous insufficiency is managed through alternative treatments focused on venous circulation rather than arterial narrowing.
