    Interventional procedures consultation document

    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 (stent) to widen or unblock an artery that supplies the heart or with conventional open-heart surgery. In this procedure, a stent is inserted through a vein in the neck. It is guided into the vessel that drains blood from the heart muscle into 1 of the right heart chambers (the coronary sinus) and expanded using a balloon. The device narrows the coronary sinus, which is thought to increase the blood to flow into the heart muscle. The aim is to reduce chest pain and improve quality of life.

    NICE is looking at coronary sinus stent insertion for refractory angina.

    NICE's interventional procedures advisory committee met to consider the evidence and the opinions of professional experts, who are consultants with knowledge of the procedure.

    This document contains the draft guidance for consultation. Your views are welcome, particularly:

    • comments on the draft recommendations

    • information about factual inaccuracies

    • additional relevant evidence, with references if possible.

    NICE is committed to promoting equality of opportunity, eliminating unlawful discrimination and fostering good relations between people with particular protected characteristics and others.

    This is not NICE's final guidance on this procedure. The draft guidance may change after this consultation.

    After consultation ends, the committee will:

    • meet again to consider the consultation comments, review the evidence and make appropriate changes to the draft guidance

    • prepare a second draft, which will go through a resolution process before the final guidance is agreed.

    Please note that we reserve the right to summarise and edit comments received during consultation or not to publish them at all if, in the reasonable opinion of NICE, there are a lot of comments or if publishing the comments would be unlawful or otherwise inappropriate.

    Closing date for comments: 22 July 2021

    Target date for publication of guidance: November 2021
