Cardiac Sinus Reducer ?

[Frogman53]

Anyone on here had one of these fitted ? I may be in line for one and I'm wondering if anyone has undergone this procedure.

Hello,

A Coronary sinus reducer is a type of stent that is placed in a large vein where the blood flows from the heart. It isn't a widely used device as as there haven't been many large scale research studies to support it's use. Most studies only have fewer than 100 participants

A coronary sinus reducer is offered to people with refractory angina and microvascular angina.

It is not certain how it works. It may slow the drainage of blood from the heart nor is it known for how long the sinus reducer continues to help reduce the symptoms of angina.

It requires an angiogram to put the device into the coronary sinus. The vein can be damaged during the insertion of the coronary sinus reducer.

This recent study from Imperial College Healthcare has some more information.

I live with a rarer type of refractory angina caused by coronary vasospasms. I was offered a coronary sinus reducer many years ago, but after doing some research I decided it wasn't the right device for me.

I sought out a Cardiologist who offered me a specialised angiogram which confirmed my diagnosis of vasospastic angina. Which I am glad I did as a coronary sinus is not thought to be useful for people living with vasospastic angina as the coronary sinus may make coronary vasospasms worse.
