There is not enough evidence about how well this procedure works. This type of procedure can cause complications. So it can only be done with special arrangements. This means you will have regular appointments afterwards to check how well it is working or if it has caused problems.
Angina is chest pain caused by reduced blood flow to the heart muscle. It is refractory when it cannot be controlled using medication, by inserting a small wire-mesh device (a stent) to unblock or widen an artery that supplies the heart or with open-heart surgery. In this procedure, a device is inserted through a vein in the neck. It is guided into the vessel (the coronary sinus) that drains blood from the heart muscle into 1 of the right heart chambers and expanded using a balloon. The device narrows the coronary sinus, which is thought to improve the flow of oxygenated blood throughout the heart muscle. The aim is to reduce chest pain and improve quality of life.
