What is the best heart stent in Singapore for blocked coronary arteries?

Doctor's Answers 2

There is no one ‘best heart stent” in Singapore or elsewhere.

There are many different stents available right from bare metal stents (used seldom nowadays) to Drug-coated stents (third and fourth generation) to absorbable stents (more recent entrants)

However different patients and blood vessels do better with different kinds of stents.

In diabetes there are certain kind of stents (depending on the drug, the polymer coating etc) which have been shown to confer a distinct advantage.

Similarly in elderly patients or those about to undergo surgery certain stents which promote faster healing (ie the polymer and drug coating disappear faster) have an advantage as the blood thinners can be reduced rapidly in a month or so.

In certain kind of blood vessels (this depends on how the vessel wall looks on intravascular imaging – IVUS or OCT) absorbable stents – made of an absorbable metal may be better but this cannot be used if the vessel has significant calcification as its quite a soft metal.

If the blood vessel is shown to have a more fibrous thickened vessel a copper-chromium alloy platinum-chromium alloy stent with thicker struts and more radial strength maybe a better choice.

Therefore multiple factors have to be taken into account before implanting a suitable stent.

A heart stent is a metal tube that's inserted into your narrowed heart artery during an angioplasty. It acts as an internal support framework to keep the artery open by pressing plaque back against the artery wall.

There are many different types of heart stents available in Singapore:

Bare Metal Stent (seldomly used nowadays) a metallic mesh tube.

Drug-eluting Stent a metallic stent that's been coated with medication to prevent re-narrowing of the heart vessel.

Bioresorbable Vascular Scaffold (BVS) – a non-metallic mesh tube that slowly dissolves once the blocked artery can function naturally again and stay open on its own.

There's no one "best heart stent”. However, there may be a better suited heart stent for you, according to your condition. This is why I alway make sure to explain the characteristic of the heart stent that you will be receiving.

What are the latest advancements in heart stent insertion and angioplasty technology?

There have been many improvements in stent technology but one of the noteworthy changes have been the ability to image better inside the arteries. This is a technique called OCT or Optical Coherence tomography which helps us to visualize upto 20 microns ie almost see the vessel live. This makes it easier to see the fat accumulation inside the blood vessel and the likelihood of the plaque rupturing and if stenting is necessary. It also helps to ensure that stent placement is optimal.
