A technique of mechanically widening a narrowed or obstructed blood vessel?

Well it really depends on the nature of the narrowing to dictate the particular course of treatment for arterial narrowing (stenosis) or obstruction (atresia). For example, if the stenosis or atresia is congenital (baby is born with it), then the baby will likely undergo a series of corrective surgeries to reconstruct the malformed vessel-- this is especially true with stenosis or atresia of the cardiovascular organs (i.e., aorta and pulmonary artery).
In contrast, when a once healthy and normal vessel has become narrowed or obstructed, it is often due to the presence and buildup of atherosclerotic plaque, likely related to chronic high cholesterol (specifically, LDL), and an angioplasty is performed (balloon inflation and removal to reopen the vessel-- see link below!) and/or a stent is placed to retain the newly widened artery.
Bottom line, it is important to remember that the smooth muscle/connective tissue composition of arteries is what allows them to be strong enough to withstand high-volume flow, but also gives the vessel a high noncompliance, and treatment of arterial stenosis or atresia can sometimes be difficult as a result.

What is another name for balloon angioplasty?
Balloon angioplasty (stents) Angioplasty is the technique of mechanically widening a narrowed or obstructed blood vessel, typically as a result of atherosclerosis. An empty and collapsed balloon on a guide wire, known as a balloon catheter, is passed into the narrowed locations and then inflated to a fixed size using water pressures some 75 to 500 times normal blood pressure (6 to 20 atmospheres). The balloon crushes the fatty deposits, opening up the blood vessel for improved flow, and the balloon is then collapsed and withdrawn.
What is the surgical widening of a constricted heart valve called?
An angioplasty is the widening of a narrowed blood vessel. A stent is a tube inserted to prevent constriction.

What is the most common heart disease?
Hi,Coronary heart disease is most commonly equated with Coronary artery disease as of now.Coronary Angioplasty is the technique of mechanically widening using a balloon in a narrowed or totally obstructed blood vessel (coronary artery) narrowed by atherosclerosis. This procedure improves blood flow to the heart.
